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.
