What is atazanavir?
Atazanavir is an antiviral medication in a group of HIV medicines called protease (PRO-tee-ayz) inhibitors. Atazanavir prevents human immunodeficiency virus (HIV) cells from multiplying in your body.

Atazanavir is used to treat HIV, which causes acquired immunodeficiency syndrome (AIDS). Atazanavir is not a cure for HIV or AIDS.

Atazanavir may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about atazanavir?
You should not take this medication if you are allergic to atazanavir.

Do not take atazanavir together with cisapride (Propulsid), ergotamine (Ergomar, Cafergot), dihydroergotamine (D.H.E. 45, Migranal Nasal Spray), ergonovine (Ergotrate), methylergonovine (Methergine), indinavir (Crixivan), irinotecan (Camptosar), lovastatin (Mevacor, Altocor), simvastatin (Zocor), pimozide (Orap), midazolam (Versed), triazolam (Halcion), rifampin (Rifadin, Rimactane, Rifater), or St. John's wort.

There are many other medicines that can interact with atazanavir. 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.

Before using atazanavir, tell your doctor if you have liver disease (including hepatitis B or C), kidney disease (or if you are on dialysis), diabetes, a bleeding disorder such as hemophilia, a heart condition called "AV block," or if you have ever used a protease inhibitor in the past.

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.

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. Be sure to read the medication guide or patient instructions provided with each of your medications. 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.

Store atazanavir at room temperature away from moisture and heat.

What happens if I miss a dose?

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose.
