Table of contents:

Combivir is a prescription medication used to treat HIV (Human Immunodeficiency Virus) infection in adults and children. It is a fixed-dose combination tablet containing two active ingredients: lamivudine and zidovudine. Both ingredients belong to a class of medications called nucleoside reverse transcriptase inhibitors.

Combivir works by preventing the virus from multiplying and spreading in the body. It is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, continue to take all HIV medications exactly as prescribed by your doctor. It can be used in combination with other antiretroviral drugs as part of a comprehensive HIV treatment regimen.

Uses and Dosage

Combivir comes in the form of a tablet to be taken by mouth with or without food as directed by a healthcare professional, usually twice daily. Take the tablet with a full glass of water (8 ounces/240 milliliters) unless instructed otherwise by a doctor. Only take this medication if prescribed by a doctor who has determined the right doses of both medications in this product for the patient. It should not be used by children weighing less than 30 kilograms (66 pounds).

Continue taking Combivir and other HIV medications exactly as prescribed, without skipping doses or changing the dose unless directed by a doctor. Skipping doses or changing the dose without approval from a doctor may increase the amount of virus in the body, make the infection more difficult to manage, result in drug resistance or worsening side effects.

  • The dosage of Combivir in HIV-1-infected adults and adolescents weighing greater than or equal to 30 kg is 1 tablet (containing 150 mg of lamivudine and 300 mg of zidovudine) taken orally twice daily.
  • The typical dosage of scored Combivir tablets for pediatric patients who weigh greater than or equal to 30 kg and for whom a solid oral dosage form is appropriate is 1 tablet administered orally twice daily.
