What is indinavir?
Indinavir is an antiviral medication in a group of HIV medicines called protease
(PRO-tee-ayz) inhibitors. Indinavir prevents human immunodeficiency virus (HIV) cells from
multiplying in your body.
Indinavir is used to treat HIV, which causes acquired immunodeficiency syndrome
(AIDS). Indinavir is not a cure for HIV or AIDS.
Indinavir may also be used for purposes other than those listed in this medication guide.
What is the most important information I should know about indinavir?
Do not take indinavir with amiodarone (Cordarone, Pacerone), cisapride (Propulsid),
pimozide (Orap), midazolam (Versed), triazolam (Halcion), or an ergot medicine such as
Ergomar, Cafergot, Wigraine, D.H.E. 45, Migranal, Methergine.
These drugs can cause life-threatening side effects if you use them while you are
taking indinavir.
There are many other medicines that can interact with indinavir. Tell your doctor about all the prescription and over-the-counter medications you use. This
includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start
using a new medication without telling your doctor. Keep a list with you of all the medicines you
use and show this list to any doctor or other healthcare provider who treats you.
HIV/AIDS is usually treated with a combination of different drugs. To best treat your
condition, use all of your medications as directed by your doctor. Do not change your doses or
medication schedule without advice from your doctor. Every person with HIV or AIDS should
remain under the care of a doctor.
Taking indinavir will not prevent you from passing HIV to other people through
unprotected sex or sharing of needles. Talk with your doctor about safe methods of preventing
HIV transmission during sex, such as using a condom and spermicide. Sharing drug or medicine
needles is never safe, even for a healthy person.
