Why is this medication prescribed?
Dolutegravir is used with other medications to treat human immunodeficiency virus (HIV) infection in adults and children who are at least 12 years of age and weigh at least 88 lb (40 kg). Dolutegravir is in a class of medications called HIV integrase inhibitors. It works by decreasing the amount of HIV in your blood and increasing the number of immune cells that help fight infections in your body. Although dolutegravir does not cure HIV, using it along with other medications 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 lifestyle changes may decrease the risk of transmitting (spreading) the HIV virus to other people.
How should this medicine be used?
Dolutegravir comes as a tablet to take by mouth once or twice a day with or without food. Take dolutegravir 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 dolutegravir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Continue to take dolutegravir even if you feel well. Do not stop taking dolutegravir without talking to your doctor. When your supply of dolutegravir runs low, get more from your doctor or pharmacist. If you stop taking dolutegravir or miss doses, your condition may become worse and more difficult to treat with medication.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
