General Info

Combivir is an HIV medication. It is in a category of HIV medicines called nucleoside reverse transcriptase inhibitors. Combivir was approved by the U.S. Food and Drug Administration for use by people living with HIV in 1997.

Combivir is a combination of two drugs: Retrovir (zidovudine) and Epivir (lamivudine). Both of these drugs can still be purchased individually for use in combination with other HIV drugs.

Combivir must be used in combination with other HIV drugs.


Dosage

Adult Dose: One tablet twice a day. Each tablet contains 300mg zidovudine + 150mg lamivudine.

Pediatric Dose: Patients weighing more than 66lbs (30kg): One tablet twice a day. Each tablet contains 300mg zidovudine + 150mg lamivudine.

Dosing Info: Take with or without food, however taking with food may minimize stomach upset.


Side Effects

Bone marrow problems, such as decreased production of red blood cells and/or white blood cells, can occur in people talking zidovudine.

A rare but potentially serious side effect of zidovudine is myopathy (damage to the muscles, including the heart). People who use zidovudine for a long period of time, meaning several years, are at the greatest risk for myopathy. General symptoms of myopathy include weakness of limbs, usually proximal (located close to the center of the body).

If you have hepatitis B and plan to stop taking Combivir, your doctor might want to frequently check your liver enzymes after stopping treatment. This is because the lamivudine in Combivir is also active against the hepatitis B virus (HBV). If lamivudine is stopped abruptly, it can cause liver disease to "flare" and damage the liver.
