Drug Info for prezcobix

The combination of darunavir and cobicistat is used, along with other medications, to treat human immunodeficiency virus (HIV) infection in adults and children who weigh at least 88 lb (40 kg). Darunavir is in a class of medications called protease inhibitors. It works by decreasing the amount of HIV in the blood. Cobicistat is in a class of medications called pharmacokinetic boosters. It works by increasing the amount of darunavir in the body so that it can have a greater effect. 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.

The Prezcobix cash price can be quite expensive at about $1,757 for a supply of 30, 150 mg/800 mg tablets.
