Common use

Isentress (raltegravir) is an antiretroviral medication prescribed for the treatment of HIV-1 infection in adults, adolescents, and children, always used in combination with other antiretroviral drugs as part of a highly active antiretroviral therapy (HAART) regimen. As the first FDA-approved integrase strand transfer inhibitor (INSTI), Isentress works by selectively blocking HIV integrase, a viral enzyme essential for inserting the HIV genetic material into the DNA of human host cells. By preventing this critical step of viral replication, raltegravir effectively reduces the HIV viral load in the bloodstream and helps restore and maintain healthy CD4+ T-cell counts, which are vital for proper immune function. Isentress is valued for its favorable resistance profile, tolerability, and minimal drug interactions compared to some other antiretroviral classes.

Dosage and direction

Isentress is taken orally, typically one 400 mg film-coated tablet twice daily, or as the 600 mg HD formulation taken as two 600 mg tablets once daily, with or without food. Chewable tablets and oral granule formulations are also available for pediatric patients. Swallow film-coated tablets whole with water; do not crush, break, or chew them. Chewable tablets may be chewed or swallowed whole. The dosage may vary depending on other antiretroviral medications in your regimen, the patient’s age, weight, kidney function, and treatment history. Follow your healthcare provider’s instructions carefully and take Isentress at the same times every day to maintain consistent drug levels in your blood and reduce the risk of developing viral resistance.

Precautions

Before starting Isentress, inform your doctor if you have liver disease (including hepatitis B or C co-infection), kidney impairment, a history of rhabdomyolysis or muscle disorders, phenylketonuria (chewable tablets contain phenylalanine), or any drug allergies. Monitor for signs of muscle pain, tenderness, weakness, or dark-colored urine, which may indicate rhabdomyolysis or myopathy. Regular laboratory monitoring of HIV viral load, CD4 count, liver function tests, and creatine kinase levels is important during treatment. Do not stop taking Isentress without consulting your healthcare provider, as abrupt discontinuation can lead to a rebound in viral load and potential development of drug-resistant HIV strains. Isentress does not cure HIV infection and does not prevent transmission to others.

Contraindications

Do not use Isentress if you are allergic to raltegravir or any component of the tablet formulation. Use with caution in patients with severe hepatic impairment or those taking medications that may have significant interactions. Patients with pre-existing liver conditions, including chronic hepatitis, should be closely monitored throughout therapy.

Possible side effect

Common side effects of Isentress raltegravir include headache, nausea, diarrhea, fatigue, insomnia, dizziness, and abdominal pain. These side effects are generally mild and manageable. More serious but less common side effects may include severe hypersensitivity reactions (rash, fever, blisters, facial swelling), hepatotoxicity (elevated liver enzymes, jaundice), rhabdomyolysis (severe muscle breakdown potentially leading to kidney failure), immune reconstitution inflammatory syndrome (IRIS), depression, or suicidal ideation. Report any severe, persistent, or unusual symptoms to your healthcare provider immediately.

Drug interaction

Isentress may interact with rifampin (a potent UGT1A1 inducer that can significantly reduce raltegravir levels), certain antacids containing aluminum or magnesium (which can decrease absorption), anticonvulsants such as phenytoin and phenobarbital, and other medications affecting hepatic glucuronidation pathways. When co-administered with rifampin, a dose adjustment of Isentress is required. Inform your healthcare provider about all prescription drugs, over-the-counter products, herbal supplements (especially St. John’s wort), and vitamins you are taking.

Missed dose

If you miss a dose of Isentress, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and resume your regular dosing schedule. Do not double the dose. Consistent adherence to your full antiretroviral regimen is critical for maintaining viral suppression and preventing drug resistance.

Overdose

In the event of an overdose, symptoms may include exaggerated side effects such as severe nausea, vomiting, headache, or dizziness. There is no specific antidote for raltegravir overdose. Seek immediate medical attention if an overdose is suspected. Treatment is supportive, and hemodialysis is not expected to efficiently remove raltegravir due to its high protein binding.

Storage

Store Isentress at room temperature between 20 and 25 degrees Celsius, away from moisture, heat, and direct light. Keep the tablets in the original bottle with the desiccant and out of the reach of children. Do not transfer tablets to other containers. Discard any unused medication after the expiration date.
