Risks From Concomitant use with Opioids; Abuse, Misuse, and Addiction; and Dependence and Withdrawal Reactions Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for 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.

The use of benzodiazepines, including diazepam injection, 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 increased frequency of serious adverse outcomes. Before prescribing diazepam injection and throughout treatment, assess each patient's risk for abuse, misuse, and addiction. The continued use of benzodiazepines may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Although diazepam injection is indicated only for intermittent use, if used more frequently than recommended, abrupt discontinuation or rapid dosage reduction of diazepam injection may precipitate acute withdrawal reactions, which can be life-threatening. For patients using diazepam injection more frequently than recommended, to reduce the risk of withdrawal reactions, use a gradual taper to discontinue diazepam injection .

Uses for diazepam

Diazepam injection is used to relieve symptoms of anxiety and alcohol withdrawal. It is also used to relieve anxiety before surgery or certain procedures. When diazepam is used before surgery, the patient will not remember some of the details about the procedure.

Diazepam injection is also used to treat seizures, including status epilepticus. It may also be used to help relax muscle or relieve muscle spasms.

Diazepam injection is a benzodiazepine. Benzodiazepines belong to the group of medicines called central nervous system (CNS) depressants, which are medicines that slow down the nervous system.

This medicine is given only by or under the direct supervision of your doctor.
