What is diazepam?
Diazepam is a benzodiazepine (ben-zoe-dye-AZE-eh-peens). Diazepam affects chemicals in the brain that may be unbalanced in people with anxiety.
Diazepam may also be used for purposes not listed in this medication guide.
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 diazepam is safe for you, tell your doctor if you have ever had:
kidney or liver disease;
epilepsy or other seizure disorder;
a drug or alcohol addiction; or
mental illness, depression, or suicidal thoughts or behavior.
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 diazepam for seizures.
When treating anxiety, alcohol withdrawal, or muscle spasms: If you take diazepam 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.
Diazepam is not approved for use by anyone younger than 6 months old. Do not give this medicine to a child without a doctor's advice.
How should I take diazepam?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Diazepam may be habit-forming. Misuse of habit-forming medicine can cause addiction, overdose, or death. Selling or giving away this medicine is against the law.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
Diazepam should be used for only a short time. Do not take this medicine for longer than 4 months without your doctor's advice.
Do not stop using diazepam suddenly, or you could have increased seizures or unpleasant withdrawal symptoms. Ask your doctor how to safely stop using diazepam.
Call your doctor at once if you feel that this medicine is not working as well as usual, or if you think you need to use more than usual.
While using diazepam, you may need frequent blood tests at your doctor's office.
Store at room temperature away from moisture, heat, and light. Keep track of your medicine. Diazepam is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Do not keep leftover diltiazem. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of diazepam can be fatal.
Overdose symptoms may include extreme drowsiness, loss of balance or coordination, limp or weak muscles, or fainting.
What should I avoid while taking diazepam?
Do not drink alcohol. Dangerous side effects could occur.
This medication may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Diazepam side effects

What other drugs will affect diazepam?
Taking diazepam with other drugs that make you sleepy or slow your breathing can cause dangerous side effects or death. Ask your doctor before taking a sleeping pill, opioid pain medicine, prescription cough medicine, a muscle relaxer, or medicine for anxiety, depression, or seizures.
Other drugs may interact with diazepam, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
