WHY is this medicine prescribed?
Darunavir is used with ritonavir (Norvir) and other medications to treat human immunodeficiency virus (HIV) infection in adults and children 3 years of age and older. Darunavir is in a class of medications called protease inhibitors. It works by decreasing the amount of HIV in the blood. Although darunavir does not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other life-style changes may decrease the risk of transmitting the HIV virus to other people.
HOW should this medicine be used?
Darunavir comes as a tablet and oral suspension (liquid) to take by mouth. It is usually taken with food and with ritonavir once or twice a day. Take darunavir at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take darunavir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Do not take darunavir without ritonavir.
Swallow the tablets whole with a drink such as water or milk. Do not chew the tablets.
Shake the suspension well right before each use to mix the medication evenly. Use the oral dosing syringe that came with the medication to withdraw the right amount of suspension from the bottle. You can swallow the suspension straight from the syringe. Wash the syringe with water and allow it to dry thoroughly after use.
Darunavir controls HIV but does not cure it. Continue to take darunavir even if you feel well. Do not stop taking darunavir without talking to your doctor. If you stop taking darunavir or skip doses, your condition may become more difficult to treat. When your supply of darunavir starts to run low, get more from your doctor or pharmacist.
