Prolonged use of zidovudine has been associated with muscle weakness (myopathy). Tell your doctor immediately if you have unusual weakness or tiredness or persistent sore throat or fever. Lactic acid build-up in the blood (lactic acidosis) and severe liver problems (hepatomegaly with steatosis) have been reported with the use of abacavir, zidovudine, and lamivudine, alone and in combination with other HIV medications. Tell your doctor immediately if you have symptoms of lactic acid build-up and liver problems, which include unusual tiredness, rapid breathing, dark urine, or yellowing eyes and skin.

Abacavir sulfate/lamivudine/zidovudine, alone or in combination with other drugs, is used to treat human immunodeficiency virus (HIV) infection. It works by slowing the growth of the virus. This medication is not intended for use in children. This medication is not a cure for HIV infection. You may continue to have illnesses associated with HIV infection. This medication does not reduce the risk of passing the virus to others through sexual contact or blood contamination. This medication contains abacavir and lamivudine. The use of abacavir, lamivudine, and tenofovir in combination may not be effective in treating HIV infection. If you are currently taking all three of these drugs, your doctor or pharmacist should carefully review your treatment plan. Consult your doctor or pharmacist for more details.
