Abacavir is a medicine used to manage HIV infection. By stopping the virus from making copies of itself, the drug helps keep the immune system stable.
Abacavir belongs to a class of medicines called nucleoside reverse transcriptase inhibitors (NRTIs). It blocks a key step the HIV virus uses to copy itself, helping keep the virus under control and supporting the immune system. Abacavir is the active compound in Triumeq and similar combination products.
Abacavir is used in people living with HIV to lower the amount of virus in the blood. It is commonly used to address:
People of various ages diagnosed with HIV may be prescribed a regimen that includes abacavir, often as part of a fixed-combination such as Triumeq.
Abacavir travels into the bloodstream and enters infected cells, where it mimics one of the building blocks the virus needs to copy its genetic material. By inserting itself into the replication process, it stops the virus from completing this step, slowing the spread of HIV throughout the body.
If you are pregnant, planning a pregnancy, or breastfeeding, discuss abacavir-containing medicines with a health professional, as special considerations may apply. People with a known hypersensitivity to abacavir or other NRTIs should avoid it.
Potential interactions
Always check the specific medication label for a complete list of interactions.
People with a history of allergic reactions to similar medicines may be more likely to develop skin or hypersensitivity issues. Those with weakened liver function might experience stronger side-effect signals, and older adults sometimes report fatigue more often.
Store Triumeq or other abacavir-containing products at room temperature, away from direct sunlight and moisture. These medicines are usually taken on a long-term basis, but the exact length of treatment depends on your individual health plan. Different brands may have varying strengths, so always follow the instructions that come with your specific product.
For Abacavir-specific instructions, refer to the medication information supplied with the product.
