Talk to your doctor about the risks of taking abacavir, dolutegravir, and lamivudine.
WHY is this medicine prescribed?
The combination of abacavir, dolutegravir, and lamivudine is used to treat HIV infection. Abacavir and lamivudine are in a class of medications called nucleoside analogue reverse transcriptase inhibitors (NRTIs) and dolutegravir is in a class of medications called integrase strand transfer inhibitors (INSTIs). They work by decreasing the amount of HIV in your blood and increasing the number of immune cells that help fight infections in your body.
Although abacavir, dolutegravir, and lamivudine will not cure HIV, these medications may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses. Taking these medications and making other lifestyle changes may decrease the risk of giving the HIV virus to other people.
HOW should this medicine be used?
The combination of abacavir, dolutegravir, and lamivudine comes as a tablet to take by mouth or tablets to be dissolved into a suspension (liquid) to be taken by mouth.

If giving the tablets for suspension, the tablets should be placed in the provided cup with 15-20 mL of drinking water (3 tablets can be placed in 15 mL but more than 3 tablets should be placed in 20 mL) and then swirl contents until tablets are completely dissolved and no lumps remain. After tablets are completely dissolved, the contents of the cup should be completely swallowed within 30 minutes. For children too young to drink from a cup, the contents of the cup may be drawn into a syringe and the medication given this way.
Continue to take abacavir, dolutegravir, and lamivudine even if you feel well. Do not stop taking abacavir, dolutegravir, and lamivudine without talking to your doctor.
