Raltegravir (RAL), sold under the brand name Isentress, is an antiretroviral medication used, together with other medication, to treat HIV/AIDS. It may also be used, as part of post exposure prophylaxis, to prevent HIV infection following potential exposure. It is taken by mouth.

Common side effects include trouble sleeping, feeling tired, nausea, high blood sugar, and headaches. Severe side effects may include allergic reactions including Stevens–Johnson syndrome, muscle breakdown, and liver problems. It is unclear if use during pregnancy or breastfeeding is safe. Raltegravir is an HIV integrase strand transfer inhibitor which blocks the functioning of HIV integrase which is needed for viral replication.

Raltegravir was approved for medical use in the United States in 2007. It is on the World Health Organization's List of Essential Medicines. In the United Kingdom it costs the NHS about 472 pounds per month. Lamivudine/raltegravir, a combination with lamivudine, is also available.
