Important warnings This medicine can cause some serious health issues

Oral route (solution)

Hydrocodone bitartrate and acetaminophen oral solution has the potential for addiction, abuse, and misuse, which can lead to overdose and death.

Assess each patient's risk before prescribing, and monitor for development of these behaviors and conditions.

To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a Risk Evaluation and Mitigation Strategy (REMS) for these products.

Serious, life-threatening, or fatal respiratory depression may occur.

Monitor closely, especially upon initiation or following a dose increase.

Accidental ingestion of hydrocodone bitartrate and acetaminophen oral solution, especially by children, can result in a fatal overdose of hydrocodone bitartrate and acetaminophen.

Prolonged use of hydrocodone bitartrate and acetaminophen oral solution during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated.

Monitor patients receiving hydrocodone bitartrate and acetaminophen oral solution and any CYP3A4 inhibitor or inducer for signs of respiratory depression or sedation.

Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death, most often with the use of acetaminophen at doses that exceed 4000 mg/day, and involving more than 1 acetaminophen-containing product.

Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death.

Reserve concomitant prescribing for patients with inadequate alternative treatment options.

Limit dosages and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation.
