Dosage and administration
Adults 18 years of age and older : 5 mL every 4 to 6 hours as needed, not to exceed 6 doses (30 mL) in 24 hours. ( 2.2 ) Measure Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution with an accurate milliliter measuring device. ( 2.1 , 5.7 ) Do not increase the dose or dosing frequency. ( 2.1 ) Prescribe for the shortest duration consistent with treatment goals. ( 2.3 ) Reevaluate patients with unresponsive cough in 5 days or sooner for possible underlying pathology. ( 2.3 ) Reevaluate patient prior to refilling. ( 2.3 ) Do not rapidly reduce or abruptly discontinue in a physically-dependent patient. (2.3) 2.1 Important Dosage and Administration Instructions Ensure accuracy when prescribing, dispensing, and administering Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution to avoid dosing errors due to confusion between mg and mL, and with other codeine and promethazine solutions of different concentrations, which could result in accidental overdose and death. Ensure the proper dose is communicated and dispensed. When writing prescriptions, include both the total dose in mg and the total dose in volume. Instruct patients and caregivers on how to accurately measure and take or administer the correct dose of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution. Administer Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution by the oral route only. Strongly advise patients and caregivers to always use a graduated oral syringe or measuring cup, with metric units of measurements (i.e., mL), to correctly measure the prescribed amount of medication. Inform patients and caregivers that oral dosing devices may be obtained from their pharmacy and to never use household teaspoons or tablespoons to measure Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution. Do not overfill. Rinse the measuring device with water after each use. Advise patients not to increase the dose or dosing frequency of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution because serious adverse events such as respiratory depression may occur with overdosage [see Warnings and Precautions (5.1) , Overdosage (10) ] . The dosage of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution should not be increased if cough fails to respond; an unresponsive cough should be reevaluated for possible underlying pathology [see Dosage and Administration (2.3) , Warnings and Precautions (5.6) ] . 2.2 Recommended Dosage Adults 18 years of age and older : 5 mL every 4 to 6 hours as needed, not to exceed 6 doses (30 mL) in 24 hours. 2.3 Monitoring, Maintenance, and Discontinuation of Therapy Prescribe Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution for the shortest duration that is consistent with individual patient treatment goals [see Warnings and Precautions (5.1) ]. Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy [see Warnings and Precautions (5.2) ]. Reevaluate patients with unresponsive cough in 5 days or sooner for possible underlying pathology, such as foreign body or lower respiratory tract disease [see Warnings and Precautions (5.6) ] . If a patient requires a refill, reevaluate the cause of the cough and assess the need for continued treatment with Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution, the relative incidence of adverse reactions, and the development of addiction, abuse, or misuse [see Warnings and Precautions (5.1) ] . Do not rapidly reduce or abruptly discontinue Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution in a physically-dependent patient [see Drug Abuse and Dependence (9.3) ] . When a patient who has been taking Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution regularly and may be physically dependent no longer requires therapy with Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution, taper the dose gradually, by 25% to 50% every 2 to 4 days, while monitoring carefully for signs and symptoms of withdrawal. If the patient develops these signs or symptoms, raise the dose to the previous level and taper more slowly, either by increasing the interval between decreases, decreasing the amount of change in dose, or both.

Warnings and precautions
Life-threatening respiratory depression in patients with chronic pulmonary disease or in elderly, cachectic, or debilitated patients : Monitor closely, particularly during initiation of therapy. ( 5.6 ) Activities requiring mental alertness : Avoid engaging in hazardous tasks requiring mental alertness such as driving or operating machinery. ( 5.8 ) Risks of use in patients with head injury, impaired consciousness, increased intracranial pressure, or brain tumors : Avoid use. May increase intracranial pressure and obscure the clinical course of head injuries. ( 5.12 ) Cardiovascular and central nervous system effects : Use with caution in patients with cardiovascular disorders. ( 5.13 ) Neuroleptic Malignant Syndrome : Monitor during therapy. ( 5.14 ) Paradoxical Reactions : Monitor during therapy. ( 5.15 ) Seizures in patients with seizure disorders : Monitor during therapy. ( 5.16 ) Bone marrow depression : Use with caution in patients with bone marrow depression. ( 5.18 ) Severe hypotension : Monitor during initiation of therapy. Avoid use in patients with circulatory shock. ( 5.19 ) Adrenal insufficiency : If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. ( 5.21 ) 5.1 Addiction, Abuse, and Misuse Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution contains codeine, a Schedule V controlled substance. As an opioid, Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution exposes users to the risks of addiction, abuse, and misuse [see Drug Abuse and Dependence (9) ], which can lead to overdose and death [see Overdosage (10) ]. Reserve Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution for use in adult patients for whom the benefits of cough suppression are expected to outweigh the risks, and in whom an adequate assessment of the etiology of the cough has been made. Assess each patient’s risk prior to prescribing Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution, prescribe Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution for the shortest duration that is consistent with individual patient treatment goals , monitor all patients regularly for the development of addiction or abuse, and refill only after reevaluation of the need for continued treatment. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution. Addiction can occur at recommended dosages and if the drug is misused or abused. The risk of opioid-related overdose or overdose-related death is increased with higher opioid doses, and this risk persists over the course of therapy. In post-marketing studies, addiction, abuse, misuse, and fatal and non-fatal opioid overdose were observed in patients with long-term opioid use [see Adverse Reactions (6) ] . Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). Opioids are sought by drug abusers and people with addiction disorders and are subject to criminal diversion. Consider these risks when prescribing or dispensing Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on the proper disposal of unused drug [see Patient Counseling Information (17) ] . Contact local state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product. 5.2 Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, including codeine, one of the active ingredients in Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution. Codeine produces dose-related respiratory depression by directly acting on the brain stem respiratory center that controls respiratory rhythm and may produce irregular and periodic breathing. Codeine is subject to variability in metabolism based upon CYP2D6 genotype, which can lead to an increased exposure to the active metabolite morphine [see Warnings and Precautions (5.3) ] . Promethazine exerts a depressant effect on the respiratory center that is independent of and additive to that of other respiratory depressants, including codeine [see Warnings and Precautions (5.4) ] . Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression includes discontinuation of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution, close observation, supportive measures, and use of opioid overdose reversal agents (e.g., naloxone or nalmefene), depending on the patient’s clinical status [see Overdosage (10) ] . Carbon dioxide (CO 2 ) retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. While serious, life-threatening, or fatal respiratory depression can occur at any time during the use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution, the risk is greatest during the initiation of therapy, when Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution is used concomitantly with other drugs that may cause respiratory depression [see Warnings and Precautions (5.10) ] , in patients with chronic pulmonary disease or decreased respiratory reserve, and in patients with altered pharmacokinetics or altered clearance (e.g. elderly, cachectic, or debilitated patients) [see Warnings and Precautions (5.6) ] .
Side effects
The following serious adverse reactions are described, or described in greater detail, in other sections: Addiction, abuse, and misuse [see Warnings and Precautions (5.1) , Drug Abuse and Dependence (9.3) ] Life-threatening respiratory depression [see Warnings and Precautions (5.2 , 5.3 , 5.4 , 5.5 , 5.6 ), Overdosage (10) ] Ultra-rapid metabolism of codeine and other risk factors for life-threatening respiratory depression in children [see Warnings and Precautions (5.3) ] Accidental overdose and death due to medication errors [see Warnings and Precautions (5.7) ] Decreased mental alertness with impaired mental and/or physical abilities [see Warnings and Precautions (5.8) ] Interactions with benzodiazepines and other CNS depressants [see Warnings and Precautions (5.10) ] Paralytic ileus, gastrointestinal adverse reactions [see Warnings and Precautions (5.11) ] Increased intracranial pressure [see Warnings and Precautions (5.12) ] Obscured clinical course in patients with head injuries [see Warnings and Precautions (5.12) ] Cardiovascular effects [see Warnings and Precautions (5.13) ] Neuroleptic Malignant Syndrome [see Warnings and Precautions (5.14) ] Paradoxical reactions, including dystonias [see Warnings and Precautions (5.15) ] Seizures [see Warnings and Precautions (5.16) ] Interactions with MAOI [see Warnings and Precautions (5.17) ] Bone marrow suppression [see Warnings and Precautions (5.18) ] Severe hypotension [see Warnings and Precautions (5.19) ] Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.20) ] Adrenal insufficiency [see Warnings and Precautions (5.21) ] The following adverse reactions have been identified during clinical studies, in the literature, or during post-approval use of codeine, promethazine, and/or phenylephrine. Because these reactions may be reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Drug interactions
No specific drug interaction studies have been conducted with Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution. Serotonergic Drugs : Concomitant use may result in serotonin syndrome. Discontinue if serotonin syndrome is suspected. ( 7.5 ) Muscle relaxants : Avoid concomitant use. ( 7.7 ) Diuretics : Codeine may reduce the efficacy of diuretics. Monitor for reduced effect. ( 7.8 ) Anticholinergic drugs : Concurrent use may cause paralytic ileus. ( 5.11 , 7.9 ) Antihypertensive drugs : Concomitant use may interfere with antihypertensive effects. ( 7.10 ) Ergot alkaloids, atropine sulfate, steroids, angiotensin, aldosterone, norepinephrine transporter inhibitors, and tricyclic antidepressants : Concomitant use may enhance the pressor response and increase the risk of hypertension. ( 7.11 ) Sympathomimetic Agents : Concomitant use may result in tachycardia, arrhythmias, serious hypertensive response and possible stroke. ( 7.12 ) 7.1 Inhibitors of CYP3A4 The concomitant use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution with CYP3A4 inhibitors, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g. ketoconazole), or protease inhibitors (e.g., ritonavir), may result in an increase in codeine plasma concentrations with subsequently greater metabolism by cytochrome CYP2D6, resulting in greater morphine levels, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression, particularly when an inhibitor is added after a stable dose of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution is achieved [see Warnings and Precautions (5.9) ] . After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, it may result in lower codeine levels, greater norcodeine levels, and less metabolism via CYP2D6 with resultant lower morphine levels [see Clinical Pharmacology (12.3) ] , resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to codeine. Avoid the use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution while taking a CYP3A4 inhibitor. If concomitant use is necessary, monitor patients for respiratory depression and sedation at frequent intervals. 7.2 CYP3A4 Inducers The concomitant use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution and CYP3A4 inducers, such as rifampin, carbamazepine, or phenytoin, can result in lower codeine levels, greater norcodeine levels, and less metabolism via 2D6 with resultant lower morphine levels [see Clinical Pharmacology ( 12.3) ] , resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence [see Warnings and Precautions (5.9) ] . After stopping a CYP3A4 inducer, as the effects of the inducer decline, codeine plasma concentrations may increase with subsequently greater metabolism by cytochrome CYP2D6, resulting in greater morphine levels [see Clinical Pharmacology (12.3) ] , which could increase or prolong both the therapeutic effects and adverse reactions, and may cause serious respiratory depression. Avoid the use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution in patients who are taking CYP3A4 inducers. If concomitant use of a CYP3A4 inducer is necessary, follow the patient for reduced efficacy. 7.3 Inhibitors of CYP2D6 Codeine is metabolized by CYP2D6 to form morphine. The concomitant use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution and CYP2D6 inhibitors, such as paroxetine, fluoxetine, bupropion, or quinidine, can increase the plasma concentration of codeine, but can decrease the plasma concentration of active metabolite morphine, which could result in reduced efficacy [see Clinical Pharmacology (12.3) ] . After stopping a CYP2D6 inhibitor, as the effects of the inhibitor decline, the codeine plasma concentration will decrease but the active metabolite morphine plasma concentration will increase, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression [see Clinical Pharmacology (12.3) ] . Avoid the use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution in patients who are taking inhibitors of CYP2D6. 7.4 Benzodiazepines, and Other CNS Depressants Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, gabapentinoids (gabapentin or pregabalin), and other opioids, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death. Avoid the use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution in patients who are taking benzodiazepines, gabapentinoids (gabapentin or pregabalin), or other CNS depressants [see Warnings and Precautions (5.10) ] . 7.5 Serotonergic Drugs The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome. If concomitant use is warranted, carefully observe the patient, particularly during treatment initiation. Discontinue Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution if serotonin syndrome is suspected. 7.6 Monoamine Oxidase Inhibitors (MAOIs) Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution is contraindicated in patients who are taking MAOIs (i.e., certain drugs used for depression, psychiatric or emotional conditions, or Parkinson’s disease) or have taken MAOIs within 14 days [see Contraindications (4) ] . MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity (e.g., respiratory depression, coma) [see Warnings and Precautions (5.17) ].
Use in specific populations
Pregnancy : Avoid use in pregnant women. May cause fetal harm. ( 8.1 ) Lactation : Breastfeeding not recommended. ( 8.2 ) Renal Impairment : Use with caution in patients with severe renal impairment. ( 8.6 ) Hepatic Impairment : Use with caution in patients with severe hepatic impairment. ( 8.7 ) 8.1 Pregnancy Risk Summary Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution is not recommended for use in pregnant women, including during or immediately prior to labor. Prolonged use of opioids during pregnancy may cause neonatal opioid withdrawal syndrome [see Warnings and Precautions (5.20) , Clinical Considerations ] . There are no available data with Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution use in pregnant women to inform a drug-associated risk for adverse developmental outcomes. Published studies with codeine have reported inconsistent findings and have important methodological limitations ( see Data ). There are reports of respiratory depression when codeine is used during labor and delivery (see Clinical Considerations ) . Reproductive toxicity studies have not been conducted with Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution; however, studies are available with individual active ingredients ( see Data ). In animal reproduction studies, codeine administered by the oral route to pregnant rats during the period of organogenesis increased resorptions and decreased fetal weights at a dose approximately 25 times the maximum recommended human dose (MRHD) in the presence of maternal toxicity ( see Data ). For pregnant mice and rats that received promethazine at doses 0.2 and 3-6 times the MRHD, during various periods of gestation, there were findings of increased fetal resorptions and skeletal fragility, decreased pup weight, and developmental delays of pups ( see Data ). In studies with normotensive pregnant rabbits, which received phenylephrine during the period of organogenesis or later, there were findings of increased fetal lethality, adverse placental effects, and possible teratogenic effects at subcutaneous doses approximately 0.8 times the MRHD on a mg/m 2 basis. Premature labor was also observed when treatment was initiated during the second trimester or later ( see Data ). Based on the animal data, advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Prolonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth. Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and failure to gain weight. The onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn. Observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly [see Warnings and Precautions (5.20) ] . Maternal use of phenylephrine can cause fetal tachycardia. Labor or Delivery Opioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in neonates. An opioid overdose reversal agent, such as naloxone or nalmefene, must be available for reversal of opioid-induced respiratory depression in the neonate. Opioids, including Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution, can prolong labor through actions which temporarily reduce the strength, duration, and frequency of uterine contractions. However, this effect is not consistent and may be offset by an increased rate of cervical dilation, which tends to shorten labor. Monitor neonates exposed to opioids during labor for signs of excess sedation and respiratory depression. Data Human Data Published data from case-control and observational studies on codeine use during pregnancy are inconsistent in their findings. Some studies of codeine exposure showed an increased risk of overall congenital malformations while others did not. An increased risk of specific malformations with codeine exposure such as respiratory malformations, spina bifida and congenital heart defects were reported in some studies. The majority of studies examining the use of phenylephrine and promethazine in pregnancy did not find an association with an increased risk of congenital anomalies. In the few studies reporting an association, no consistent pattern of malformations was noted. Most of the studies, both positive and negative, were limited by small sample size, recall bias and lack of information regarding dose and timing of exposure. Animal Data Reproductive toxicity studies have not been conducted with Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution; however, studies are available with individual active ingredients. Codeine In an embryofetal development study in pregnant rats dosed throughout the period of organogenesis, codeine increased resorptions and decreased fetal weights at a dose approximately 25 times the MRHD (on a mg/m 2 basis with a maternal oral dose of 120 mg/kg/day); however, these effects occurred in the presence of maternal toxicity.

Codeine In an embryofetal development study in pregnant rats dosed throughout the period of organogenesis, codeine increased resorptions and decreased fetal weights at a dose approximately 25 times the MRHD (on a mg/m 2 basis with a maternal oral dose of 120 mg/kg/day); however, these effects occurred in the presence of maternal toxicity. In embryofetal development studies with pregnant rabbits and mice dosed throughout the period of organogenesis, codeine produced no adverse developmental effects at doses approximately 15 and 65 times, respectively, the MRHD (on a mg/m 2 basis with maternal oral doses of 30 mg/kg/day in rabbits and 600 mg/kg/day in mice).
Pediatric use
8.4 Pediatric Use Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution is not indicated for use in patients younger than 18 years of age because the benefits of symptomatic treatment of cough associated with allergies or the common cold do not outweigh the risks for use of codeine in these patients [see Indications (1) , Warnings and Precautions (5.5) ] . Life-threatening respiratory depression and death have occurred in children who received codeine [see Warnings and Precautions (5.2) ] . In most of the reported cases, these events followed tonsillectomy and/or adenoidectomy, and many of the children had evidence of being ultra-rapid metabolizers of codeine (i.e., multiple copies of the gene for cytochrome P450 isoenzyme 2D6 or high morphine concentrations). Children with sleep apnea may be particularly sensitive to the respiratory depressant effects of codeine. Life-threatening respiratory depression and death have also occurred in children who received promethazine [see Warnings and Precautions (5.4) ] . Because of the risk of life-threatening respiratory depression and death: Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution is contraindicated for all children younger than 12 years of age [see Contraindications (4) ] . Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution is contraindicated for post-operative management in pediatric patients younger than 18 years of age following tonsillectomy and/or adenoidectomy [see Contraindications (4) ] . Avoid the use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution in adolescents 12 to 18 years of age who have other risk factors that may increase their sensitivity to the respiratory depressant effects of codeine unless the benefits outweigh the risks. Risk factors include conditions associated with hypoventilation, such as postoperative status, obstructive sleep apnea, obesity, severe pulmonary disease, neuromuscular disease, and concomitant use of other medications that cause respiratory depression [see Warnings and Precautions (5.3 , 5.6 )].
Geriatric use
8.5 Geriatric Use Clinical studies have not been conducted with Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution in geriatric populations. Use caution when considering the use of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution in patients 65 years of age or older. Elderly patients may have increased sensitivity to codeine; greater frequency of decreased hepatic, renal, or cardiac function; or concomitant disease or other drug therapy [see Warnings and Precautions (5.6) ] . Respiratory depression is the chief risk for elderly patients treated with opioids, including Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution. Respiratory depression has occurred after large initial doses of opioids were administered to patients who were not opioid-tolerant or when opioids were co-administered with other agents that depress respiration [see Warnings and Precautions (5.6 , 5.10 )] . Codeine is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, monitor these patients closely for respiratory depression, sedation, and hypotension.
Overdosage
Clinical Presentation Codeine Acute overdose with codeine is characterized by respiratory depression (a decrease in respiratory rate and/or tidal volume, Cheyne-Stokes respiration, cyanosis), extreme somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, partial or complete airway obstruction, atypical snoring, hypotension, hypoglycemia, circulatory collapse, cardiac arrest, and death. Toxic leukoencephalopathy has been reported after opioid overdose and can present hours, days, or weeks after apparent recovery from the initial intoxication. Codeine may cause miosis, even in total darkness. Pinpoint pupils are a sign of opioid overdose but are not pathognomonic (e.g., pontine lesions of hemorrhagic or ischemic origin may produce similar findings). Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations [see Clinical Pharmacology (12.2) ] . Promethazine Signs and symptoms of overdosage with promethazine range from mild depression of the central nervous system and cardiovascular system to profound hypotension, respiratory depression, unconsciousness and sudden death. Other reported reactions include hyperreflexia, hypertonia, ataxia, athetosis and extensor-plantar reflexes (Babinski reflex). Stimulation may be evident, especially in children and geriatric patients. Convulsions may rarely occur. A paradoxical reaction has been reported in children receiving single doses of 75 mg to 125 mg orally, characterized by hyperexcitability and nightmares. Atropine-like signs and symptoms (dry mouth, fixed dilated pupils, flushing, tachycardia, hallucinations, gastrointestinal symptoms, convulsions, urinary retention, cardiac arrhythmias and coma) may be observed. Impaired secretion from sweat glands following toxic doses of drugs with anticholinergic side effects may predispose to hyperthermia. Phenylephrine Signs and symptoms of overdosage with phenylephrine include headache, vomiting, hypertension, reflex bradycardia, cardiac arrhythmias including ventricular premature beats and ventricular tachycardia, convulsions, and cerebral hemorrhage. Overdosage may also be associated with a sensation of fullness in the head and tingling of the extremities. Headache may be a symptom of hypertension. Bradycardia may be seen early in phenylephrine overdosage through stimulation of baroreceptors. Treatment of Overdose Treatment of overdosage is driven by the overall clinical presentation, and consists of discontinuation of Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution together with institution of appropriate therapy. Give primary attention to the reestablishment of adequate respiratory exchange through provision of a patent and protected airway and the institution of assisted or controlled ventilation. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support techniques. Gastric emptying may be useful in removing unabsorbed drug. For clinically significant respiratory or circulatory depression secondary to codeine overdose, administer an opioid overdose reversal agent such as naloxone or nalmefene. An opioid overdose reversal agent should not be administered in the absence of clinically significant respiratory depression. Because the duration of opioid reversal is expected to be less than the duration of action of codeine in Promethazine and Phenylephrine HCl and Codeine Phosphate Oral Solution, carefully monitor the patient until spontaneous respiration is reliably re-established. If the response to an opioid overdose reversal agent is suboptimal or only brief in nature, administer additional reversal agent as directed by the product’s prescribing information. The respiratory depressant effects of promethazine are not reversed by opioid overdose reversal agents, such as naloxone or nalmefene. Because of the potential for promethazine to reverse epinephrine’s vasopressor effect, epinephrine should NOT be used to treat hypotension associated with promethazine overdose. Hemodialysis is not routinely used to enhance the elimination of codeine or promethazine from the body. Adrenergic receptor blocking agents (beta-blockers), such as propranolol, may be used for the treatment of cardiac toxicity due to phenylephrine.

Mechanism of action
12.1 Mechanism of Action Codeine Codeine is an opioid agonist relatively selective for the mu-opioid receptor, but with a much weaker affinity than morphine. The analgesic and antitussive properties of codeine have been speculated to come from its conversion to morphine. The precise mechanism of action of codeine and other opiates is not known; however, codeine is believed to act centrally on the cough center. In excessive doses, codeine will depress respiration. Promethazine Promethazine is a phenothiazine derivative, which differs structurally from the antipsychotic phenothiazines by the presence of a branched side chain and no ring substitution. Promethazine possesses antihistamine (H 1 receptor antagonist), antiemetic, sedative, and anticholinergic effects. It prevents released histamine from dilating capillaries and causing edema of the respiratory mucosa. Phenylephrine Phenylephrine is a sympathomimetic amine that exerts a decongestant action on the nasal mucosa via alpha adrenergic receptor activity. It has the potential for excitatory side effects.
