What is diazepam?
Diazepam is a benzodiazepine (ben-zoe-dye-AZE-eh-peen)). It is thought that benzodiazepines work by enhancing the activity of certain neurotransmitters in the brain.
Diazepam is sometimes used with other medications to treat seizures.
Diazepam can slow or stop your breathing, especially if you have recently used an opioid medication, alcohol, or other drugs that can slow your breathing.
MISUSE OF diazepam CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.
You should not use this medicine if you are allergic to diazepam or similar medicines (Klonopin>, Xanax, and others), or if you have myasthenia gravis, severe liver disease, narrow-angle glaucoma, a severe breathing problem, or sleep apnea.
MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Fatal side effects can occur if you use this medicine with opioid medicine, alcohol, or other drugs that cause drowsiness or slow your breathing.
