Diazepam may increase the risk of serious or life-threatening breathing problems, sedation, or coma if used along with certain medications. Tell your doctor if you are taking or plan to take certain opiate medications for cough such as codeine (in Triacin-C, in Tuzistra XR) or hydrocodone (in Anexsia, in Norco, in Zyfrel) or for pain such as codeine (in Fiorinal), fentanyl (Actiq, Duragesic, Subsys, others), hydromorphone (Dilaudid, Exalgo), meperidine (Demerol), methadone (Dolophine, Methadose), morphine (Astramorph, Duramorph PF, Kadian), oxycodone (in Oxycet, in Percocet, in Roxicet, others), and tramadol (Conzip, Ultram, in Ultracet). Your doctor may need to change the dosages of your medications and will monitor you carefully. If you take diazepam with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care immediately: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own.
Drinking alcohol or using street drugs during your treatment with diazepam also increases the risk that you will experience these serious, life-threatening side effects. Do not drink alcohol or use street drugs during your treatment.
Why is this medication prescribed?
Diazepam is used to relieve anxiety, muscle spasms, and seizures and to control agitation caused by alcohol withdrawal.
How should this medicine be used?
Diazepam comes as a tablet, extended-release (long-acting) capsule, and concentrate (liquid) to take by mouth. Do not open, chew, or crush the extended-release capsules; swallow them whole. It is usually taken 1 to 4 times a day and may be taken with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take diazepam exactly as directed.
Diazepam concentrate (liquid) comes with a specially marked dropper for measuring the dose. Ask your pharmacist to show you how to use the dropper. Dilute the concentrate in water, juice, or carbonated beverages just before taking it. It also may be mixed with applesauce or pudding just before taking the dose.
Diazepam can be habit-forming. Do not take a larger dose, take it more often, or for a longer time than your doctor tells you to. Tolerance may develop with long-term or excessive use, making the drug less effective. This medication must be taken regularly to be effective. Do not skip doses even if you feel that you do not need them. Do not take diazepam for more than 4 months or stop taking this medication without talking to your doctor. Stopping the drug suddenly can worsen your condition and cause withdrawal symptoms (anxiousness, sleeplessness, and irritability). Your doctor probably will decrease your dose gradually.
Other uses for this medicine
Diazepam is also used to treat irritable bowel syndrome and panic attacks. Talk to your doctor about the possible risks of using this drug for your condition.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
What special precautions should I follow?
Before taking diazepam,
- tell your doctor and pharmacist if you are allergic to diazepam, alprazolam (Xanax), chlordiazepoxide (Librium, in Librax), clonazepam (Klonopin), clorazepate (Gen-Xene, Tranxene), estazolam, flurazepam, lorazepam (Ativan), oxazepam, temazepam (Restoril), triazolam (Halcion), any other medications, or any of the ingredients in diazepam products. Ask your pharmacist for a list of the ingredients.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, and nutritional supplements, you are taking. Be sure to mention any of the following: antihistamines; cimetidine (Tagamet); digoxin (Lanoxin); disulfiram (Antabuse); fluoxetine (Prozac); isoniazid (Laniazid, in Rifamate, in Rifater); ketoconazole (Nizoral); levodopa (in Ritary, in Sinemet, in Stalevo); medications for depression, seizures, Parkinson's disease, asthma, colds, or allergies; metoprolol (Lopressor, Toprol XL); muscle relaxants; oral contraceptives; probenecid (Probalan, in Col-Probenecid); propranolol (Hemangeol, Inderal, Innopran); ranitidine (Zantac); rifampin (Rifadin, Rimactane, in Rifamate, in Rifater); sedatives; sleeping pills; theophylline (Elixophyllin, Theo 24, Theochron); tranquilizers; or valproic acid (Depakene). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- if you use antacids, take diazepam first, then wait 1 hour before taking the antacid.
- tell your doctor if you have or have ever had glaucoma; seizures; or lung, heart, or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking diazepam, call your doctor immediately.
- talk to your doctor about the risks and benefits of taking diazepam if you are 65 years of age or older. Older adults should not usually take diazepam because it is not as safe as other medications that can be used to treat the same conditions.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking diazepam.
- you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
- tell your doctor if you use tobacco products. Cigarette smoking may decrease the effectiveness of this medication.
What should I do if I forget a dose?
If you take several doses per day and miss a dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
What side effects can this medication cause?

If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).
What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
In case of emergency/overdose
In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.
What other information should I know?
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to diazepam.
Diazepam can cause false results in urine tests for sugar using Clinistix and Diastix. Diabetic patients should use TesTape to test their urine for sugar.
If you are taking diazepam to control seizures and have an increase in their frequency or severity, call your doctor. Your dose may need to be adjusted. If you use diazepam for seizures, carry identification (Medic Alert) stating that you have epilepsy and that you are taking diazepam.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
