What is diazepam?
Diazepam is a benzodiazepine (ben-zoe-dye-AZE-eh-peens). It is thought that diazepam works by enhancing the activity of certain neurotransmitters in the brain.
Diazepam is used to treat anxiety disorders, alcohol withdrawal symptoms, or muscle spasms.
Diazepam is sometimes used with other medications to treat seizures.
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.
Do not give this medication to a child younger than 6 months old.
Before taking this medicine
You should not use this medicine if you are allergic to diazepam or similar drugs (Klonopin, Xanax, and others), or if you have:
myasthenia gravis (a muscle weakness disorder);
severe liver disease;
a severe breathing problem;
sleep apnea (breathing stops during sleep); or
alcoholism, or addiction to drugs similar to diazepam.
To make sure this medicine is safe for you, tell your doctor if you have ever had:
kidney or liver disease;

When treating seizures, do not start or stop taking diazepam during pregnancy without your doctor's advice. Diazepam may cause harm to an unborn baby, but having a seizure during pregnancy could harm both the mother and the baby. Tell your doctor right away if you become pregnant while taking this medicine for seizures.
When treating anxiety, alcohol withdrawal, or muscle spasms: If you take this medicine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.
Diazepam can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.
