Abacavir is used along with other medications to treat human immunodeficiency virus (HIV) infection. Abacavir is in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). It works by decreasing the amount of HIV in the blood. Although abacavir 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 (spreading) the HIV virus to other people.
Abacavir comes as a tablet and a solution (liquid) to take by mouth. It is usually taken one or two times a day with or without food. Take abacavir 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 abacavir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Abacavir helps to control HIV infection, but does not cure it. Continue to take abacavir even if you feel well. Do not stop taking abacavir without talking to your doctor. If you stop taking abacavir or skip doses, your condition may become more difficult to treat or you could have an allergic reaction when restarting the medication (See Important Warning section). Do not run out of medication. When your supply of abacavir starts to run low, get more from your doctor or pharmacist.
Abacavir is also used in combination with other antiviral medications to prevent HIV infection in people who have been exposed to it. Talk to your doctor about the possible risks of using this medication for your condition.
