Overactive immune system
- Risk factors: Current untreated infection
Taking HIV medications, such as Isentress (raltegravir), can cause an intense immune response called immune reconstitution syndrome. Your immune system becomes stronger and more active once you start taking Isentress (raltegravir) to treat HIV. Your immune system then begins to fight off any infections in the body that it was too weak to defend against before. This intense immune response can lead to a lot of inflammation.
In rare situations, your immune system can become so strong that it starts to attack healthy cells in your body, which can lead to certain autoimmune conditions. These autoimmune problems can develop after many months of taking Isentress (raltegravir).
Call your prescriber if you have a fever, difficulty breathing, cough, or any unusual, sudden changes to your health after you start Isentress (raltegravir). These might be signs and symptoms of immune reconstitution syndrome and its complications.
Risk for muscle damage
- Risk factors: Taking other medications that can cause muscle pain or muscle damage, like statins | History of rhabdomyolysis

In fact, some people had muscle pain or even developed rhabdomyolysis (or "rhabdo"), severe muscle breakdown that can be serious and can lead to kidney damage. Get medical help right away if you start having symptoms of rhabdomyolysis, such as severe muscle pain, weakness all over your body, or brownish-red urine.
