Warning: Risks From Concomitant Use With Opioids; Abuse, Misuse, and Addiction; and Dependence and Withdrawal ReactionsConcomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.The use of benzodiazepines, include chlordiazepoxide hydrochloride, a component of Librax®, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes. Before prescribing chlordiazepoxide hydrochloride/clidinium bromide and throughout treatment, assess each patient's risk for abuse, misuse, and addiction.The continued use of benzodiazepines, including chlordiazepoxide hydrochloride/clidinium bromide, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Abrupt discontinuation or rapid dosage reduction of chlordiazepoxide hydrochloride/clidinium bromide after continued use may precipitate acute withdrawal reactions, which can be life-threatening. To reduce the risks of withdrawal reactions, use a gradual taper to discontinue chlordiazepoxide hydrochloride/clidinium bromide or reduce the dosage.
