What is the most important information I should know about efavirenz (Sustiva)?

Efavirenz may cause serious psychiatric symptoms including confusion, severe depression, suicidal thoughts, aggression, extreme fear, hallucinations, or unusual behavior. Contact your doctor at once if you have any of these side effects, even if you have had them before.

Do not take efavirenz with cisapride (Propulsid), pimozide (Orap), midazolam (Versed), triazolam (Halcion), or ergot medicines such as dihydroergotamine (D.H.E. 45), ergonovine (Ergotrate), ergotamine (Ergomar, Cafergot, Wigraine), or methylergonovine (Methergine). These drugs can cause life-threatening side effects if you use them while you are taking efavirenz.

There are many other medicines that can interact with efavirenz, or make it less effective. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.

Taking this medication will not prevent you from passing HIV to other people. Talk with your doctor about safe methods of preventing HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person.
