CABOTEGRAVIR helps manage the symptoms of 
HIV infection. It may also be used for 
PrEP (
pre-exposure prophylaxis), which helps lower the risk of getting 
HIV through sex. It works by limiting the spread of HIV in the body. This medication is not a cure for HIV or AIDS and it may still be possible to spread HIV to others while taking it. It does not prevent other sexually transmitted infections (STIs).
