How It Works

Abacavir is converted inside cells into an active metabolite that inhibits HIV reverse transcriptase. This interferes with the conversion of HIV RNA into DNA and helps prevent the virus from multiplying. Abacavir is used with other antiretroviral medicines as part of a complete HIV treatment regimen.

Uses

Abacavir 300mg is used in combination with other antiretroviral medicines for the treatment of HIV-1 infection. It does not cure HIV, but effective combination therapy can suppress the virus, improve immune function, and reduce the risk of HIV-related complications.

Before starting abacavir, healthcare professionals generally assess HLA-B*5701 status because abacavir can cause a potentially serious hypersensitivity reaction in susceptible individuals.
