-Use of this product may lead to opioid addiction, abuse, and misuse, which can lead to overdose and death.
-Reserve use of this drug for adults for whom cough suppression benefits outweigh risks, and who have had adequate assessment of the cough etiology.
-Assess each patients risks prior to prescribing; prescribe for the shortest duration consistent with individual treatment goals, and monitor all patients regularly for development of addiction or abuse; refill only after evaluating the need for continued treatment.
-Serious, life-threatening, or fatal respiratory depression may occur with use.
-Monitor for respiratory depression, especially at the beginning of therapy or in high risk patients.
-Accidental ingestion of even one dose of this drug, especially by children, can cause a fatal overdose of hydrocodone.
-Ensure accuracy when prescribing, dispensing, and administering this drug.
-Dosing errors can cause accidental overdose and death.
-Always use an accurate milliliter measuring device when measuring and administering liquid medications.
-Concomitant use with all CYP450 3A4 inhibitors may increase plasma hydrocortisone concentrations, potentially increasing or prolonging adverse drug effects, and may potentially lead to fatal respiratory depression.
-Discontinuing a concomitant CYP450 3A4 inducer may cause increased plasma hydrocodone concentration.
-Avoid use in patients taking CYP450 3A4 inhibitors or inducers.
-Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Avoid use of opioid cough medications in patients taking benzodiazepines, other CNS depressants, or alcohol.
-Instruct patients not to consume alcohol or use prescription or non-prescription products containing alcohol while on this medication.
-Co-ingestion with alcohol may cause increased plasma levels and a potentially fatal overdose of hydrocodone.
-Use is not recommended in pregnant women.
-Prolonged use during pregnancy may cause neonatal opioid withdrawal syndrome, which can be life-threatening if not recognized and treated, and requires management according to neonatology expert protocols.
-If used for a prolonged period during pregnancy, advise the patient of the neonatal opioid withdrawal syndrome risk and ensure appropriate treatment will be available.
