What is Abacavir, Dolutegravir, and Lamivudine used for?
Last updated September 6, 2026.
**Abacavir, dolutegravir, and lamivudine are combined to treat HIV infection and help protect your immune system.** This prescription combination, sold as Triumeq, lowers the amount of HIV in your blood but does not cure HIV. Your clinician checks your treatment history, kidney and liver health, hepatitis B status, and a genetic test for abacavir allergy risk before prescribing it. You take your prescribed dose once daily, with or without food. Taking it consistently and keeping your blood test appointments helps you maintain control of HIV.
What to do
- **Complete screening:** Confirm your clinician has reviewed your genetic allergy test and hepatitis B results before you start.
- **Build a routine:** Take your prescribed dose at the same time each day and refill before you run out.
- **Check interactions:** Ask your pharmacist how to time antacids, iron, and calcium around your dose.
- **Know allergy symptoms:** Stop taking the medicine and contact your clinician immediately if you suspect an allergic reaction, such as fever with rash.
- **Avoid restarting after allergy:** Never take abacavir again if you have had an allergic reaction to it.
- **Discuss hepatitis B:** If you also have hepatitis B, ask your clinician about additional treatment because this combination alone is insufficient.
