Why is this medication prescribed?
Raltegravir is used along with other medications to treat human immunodeficiency virus (HIV) infection. Raltegravir is in a class of medications called HIV integrase inhibitors. It works by decreasing the amount of HIV in the blood. Although raltegravir 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.
How should this medicine be used?
Raltegravir comes as a tablet to take by mouth. It is usually taken with or without food twice a day. Take raltegravir at the same times 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 raltegravir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Continue to take raltegravir even if you feel well. Do not stop taking raltegravir or your other anti-HIV medications without talking to your doctor. If you stop taking raltegravir or skip doses, your condition may become worse and the virus may become resistant to treatment.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
