What Hydrocodone bitartrate and Chlorpheniramine maleate is and how it works

Uses, formulations, monitoring, and supply rules can differ by patient, product, and country. Follow the exact local product information and professional advice.

Mechanism of action: how Hydrocodone bitartrate and Chlorpheniramine maleate works

Hydrocodone is a semi-synthetic opioid agonist that suppresses the cough reflex by direct action on the cough center in the medulla of the brain. Chlorpheniramine is a first-generation antihistamine that competitively inhibits histamine H1 receptors, reducing allergic symptoms such as sneezing and rhinorrhea. This class of product (hydrocodone polistirex/chlorpheniramine polistirex extended-release suspension) carries an FDA boxed warning and, since January 2018, is restricted to adults 18 years and older.

Serious warnings

FDA BOXED WARNING (the strongest warning the FDA requires) — serious

Symptoms: FDA BOXED WARNING (the strongest warning the FDA requires): (1) Addiction, abuse, and misuse, which can lead to overdose and death. (2) Life-threatening respiratory depression. (3) Accidental ingestion, especially by children, can result in fatal overdose. (4) Concomitant use with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. (5) Prolonged use during pregnancy can result in neonatal opioid withdrawal syndrome in the newborn, which may be life-threatening if not recognized and treated.

Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2)

Additional warnings from the clinician database, consistent with the boxed warning above — serious

Symptoms: Additional warnings from the clinician database, consistent with the boxed warning above: use with caution in elderly or debilitated patients. In January 2018 the FDA restricted hydrocodone- and codeine-containing cough/cold medicines to adults 18 years and older, removing pediatric indications entirely, because risks in children of all ages were found to generally outweigh benefits.

Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2)

Contraindications recorded in the clinician database — serious

Symptoms: Contraindications recorded in the clinician database: Contraindications include significant respiratory depression, acute or severe bronchial asthma, known hypersensitivity to either component, and use with MAO inhibitors. Use with caution in patients with chronic pulmonary disease, head injury, increased intracranial pressure, hepatic or renal impairment, elderly, or those with a history of substance abuse.

Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2)

Interactions

Medicine or testEffectAction
Recorded interactionsHydrocodone/Chlorpheniramine can interact with other medications that cause drowsiness, such as benzodiazepines, other opioids, sleep aids, muscle relaxants, and alcohol. It may also interact with MAO inhibitors, certain antidepressants, and anticholinergic drugs. Always inform your healthcare provider of all medications and supplements you are taking. (2)

Pregnancy, breastfeeding, kidney/liver function, age

Pregnancy

Not recommended during pregnancy except when a clinician has specifically determined the benefits outweigh the risks. Prolonged opioid use during pregnancy can cause neonatal opioid withdrawal syndrome in the newborn, which can be life-threatening if not recognized and treated. Discuss any pregnancy or plans to become pregnant with your healthcare provider before continuing this medicine. (2)

Breastfeeding

Not recommended during breastfeeding per the clinician database; opioids pass into breast milk and can cause serious harm, including excess sedation and respiratory depression, in a breastfed infant. Discuss safer alternatives with your healthcare provider. (2)

Children

Frequency: Not applicable — not indicated for pediatric use.. Weight Based: Not recommended for pediatric use.. Max Daily Dose: Not applicable.. Max Single Dose: Not applicable.. Age Restrictions: Since January 2018, the FDA has restricted hydrocodone-containing cough/cold products to adults 18 years and older; they are not indicated for any pediatric age group in the US, regardless of older labeling that may still describe pediatric dosing.

Dose summary: 5 mL (containing 10 mg hydrocodone and 8 mg chlorpheniramine, as the extended-release polistirex formulation) every 12 hours; maximum 10 mL in 24 hours.

Adults 18 years and older only.

Renal context: Renal/hepatic-impairment-specific dose adjustment is not established in the clinician-authored database content or the FDA source reviewed for this medicine; use with caution per the clinician database, individualized by the prescriber. (2)
