⬛ Boxed warning (the FDA's strongest warning)

The boxed warning, the strongest warning on the label, has three parts. (1) Taking benzodiazepines with opioids may cause severe sleepiness, slowed or stopped breathing, coma, and death. Doctors should reserve this combination for people who have no adequate alternative, use the lowest dose for the shortest time, and watch closely for breathing problems and sedation. (2) Benzodiazepines expose users to risks of abuse, misuse, and addiction, which can lead to overdose or death. This risk is higher when they are combined with alcohol, other medicines, or street drugs. You can develop an addiction even when taking the medicine as prescribed. (3) Continued use may lead to physical dependence. The risk rises with longer treatment and higher daily doses. Stopping suddenly or cutting the dose quickly can cause withdrawal reactions that can be life-threatening, including seizures. A gradual taper is used to reduce this risk.

The label mentions a pregnancy registry, the National Pregnancy Registry for Psychiatric Medications (1-866-961-2388).
