Indications & Clinical Uses

Raltegravir 400mg tablets are prescribed as part of combination antiretroviral therapy for HIV-1 infection. They are used to treat adults and children who weigh at least 25 kg. This medication helps lower the amount of HIV in the body, improving immune function. It is not a cure for HIV or AIDS but supports long-term viral suppression.

Side Effects

Raltegravir works by interfering with the integrase enzyme, which HIV needs to multiply. By reducing viral replication, it helps maintain healthier immune system function. Patients may notice improved energy levels and reduced frequency of infections over time. Effects vary by individual and depend on consistent use.

Precautions & Warnings

Keep Isentress 400mg tablets in their original container with the desiccant to protect from moisture. Store at room temperature and avoid exposure to heat or direct sunlight. Do not remove tablets from the blister pack until ready to take. Keep out of reach of children and pets. If the pack is damaged, consult a healthcare provider before use.

Avoid Interactions

Raltegravir may interact with other medications, including certain antacids, supplements, and drugs that affect liver enzymes. Always inform your healthcare provider about all prescription, over-the-counter, and herbal products you are using. Alcohol and grapefruit products may also affect how Raltegravir works. A healthcare professional can assess potential risks.
