Common Use

Isentress (raltegravir) is indicated for the treatment of HIV‑1 infection in combination with other antiretroviral agents. As an integrase inhibitor, raltegravir blocks the HIV integrase enzyme, preventing viral replication and helping to control infection while preserving immune function.

Dosage and Administration

Isentress is taken orally, typically twice daily, with or without food. Tablets should be swallowed whole; chewable tablets may be chewed as appropriate. Dosage may be adjusted based on concomitant antiretrovirals, renal function, or patient response. Follow the prescribing clinician's instructions precisely.

Precautions

Inform your healthcare provider if you have liver or kidney disease, a history of muscular disorders, or known allergies. Monitor for signs of muscle pain, weakness, or dark urine, and do not discontinue therapy without medical guidance to avoid resistance development.

Contraindications

Avoid use of Isentress in patients with hypersensitivity to raltegravir or any excipients. Caution is required in individuals with severe hepatic impairment or when co‑administered with drugs that influence liver enzymes.
