Warning: Addiction, abuse, and misuse; life-threatening respiratory depression; accidental ingestion; medication errors; cytochrome P450 3A4 interaction; concomitant use with benzodiazepines or other CNS depressants; interaction with alcohol; neonatal opioid withdrawal syndromeAddiction, Abuse, and MisuseHydrocodone bitartrate/pseudoephedrine hydrochloride exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Reserve hydrocodone bitartrate/pseudoephedrine hydrochloride 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 hydrocodone bitartrate/pseudoephedrine hydrochloride, prescribe hydrocodone bitartrate/pseudoephedrine hydrochloride 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.Life-Threatening Respiratory DepressionSerious, life-threatening, or fatal respiratory depression may occur with use of hydrocodone bitartrate/pseudoephedrine hydrochloride. Monitor for respiratory depression, especially during initiation of hydrocodone bitartrate/pseudoephedrine hydrochloride or when used in patients at higher risk.Accidental IngestionAccidental ingestion of even one dose of hydrocodone bitartrate/pseudoephedrine hydrochloride, especially by children, can result in a fatal overdose of hydrocodone.Risk of Medication ErrorsEnsure accuracy when prescribing, dispensing, and administering hydrocodone bitartrate/pseudoephedrine hydrochloride. Dosing errors can result in accidental overdose and death. Always use an accurate milliliter measuring device when measuring and administering hydrocodone bitartrate/pseudoephedrine hydrochloride.Cytochrome P450 3A4 InteractionThe concomitant use of hydrocodone bitartrate/pseudoephedrine hydrochloride with all cytochrome P450 3A4 inhibitors may result in an increase in hydrocodone plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in hydrocodone plasma concentration. Avoid the use of hydrocodone bitartrate/pseudoephedrine hydrochloride in patients taking a CYP3A4 inhibitor or inducer.Risk from Concomitant Use with Benzodiazepines or Other CNS DepressantsConcomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Avoid the use of hydrocodone bitartrate/pseudoephedrine hydrochloride in patients taking benzodiazepines, other CNS depressants, or alcohol.Interaction with AlcoholInstruct patients not to consume alcoholic beverages or use prescription or non-prescription products that contain alcohol while taking hydrocodone bitartrate/pseudoephedrine hydrochloride. The co-ingestion of alcohol with hydrocodone bitartrate/pseudoephedrine hydrochloride may result in increased plasma levels and a potentially fatal overdose of hydrocodone.Neonatal Opioid Withdrawal SyndromeHydrocodone bitartrate/pseudoephedrine hydrochloride is not recommended for use in pregnant women. Prolonged use of hydrocodone bitartrate/pseudoephedrine hydrochloride during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If hydrocodone bitartrate/pseudoephedrine hydrochloride is used for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available .

Uses For Rezira
Hydrocodone and pseudoephedrine combination is used in adults to relieve cough and nasal congestion (stuffy nose) caused by the common cold.
Hydrocodone is a narcotic antitussive (cough suppressant). It acts directly on the cough center in the brain to relieve cough. Pseudoephedrine is a decongestant, which decreases nasal congestion by narrowing the blood vessels and reducing blood flow to the nasal passage.
When hydrocodone is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing cough and nasal congestion should not let the fear of dependence keep them from using narcotics to relieve their cough. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.
This medicine is available only with your doctor's prescription.
