Drug information provided by: Merative, Micromedex®
It is very important that your doctor check your or your child's progress at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.
Zidovudine may cause blood problems. These problems may result in a greater chance of certain infections and slow healing. Therefore, you should be careful when using regular toothbrushes, dental floss, and toothpicks not to damage your or your child's gums. Check with your or your child's medical doctor or dentist if you have any questions about proper oral hygiene (mouth care) during treatment with this medicine.
Check with your doctor if you or your child has muscle pain, tenderness, wasting, or unusual tiredness or weakness while you are using this medicine.
Zidovudine may cause blood and bone marrow problems. Symptoms of bone marrow problems include fever, chills, sore throat pale skin, or unusual tiredness or weakness. These problems may require blood transfusions or temporarily stopping treatment with zidovudine. Check with your or your child's doctor if any new health problems or symptoms occur while you or your child are taking zidovudine.
Two rare but serious reactions to this medicine are lactic acidosis (too much acid in the blood) and liver toxicity, which includes an enlarged liver. These are more common if you are female, very overweight (obese), or have been taking anti-HIV medicines for a long time. Call your doctor right away if you or your child have more than one of these symptoms: abdominal discomfort or cramping, dark urine, decreased appetite, diarrhea, general feeling of discomfort, light-colored stools, muscle cramping or pain, nausea, unusual tiredness or weakness, trouble breathing, vomiting, or yellow eyes or skin.
Your immune system may get stronger when you start taking HIV medicines. Tell your doctor right away if you or your child notices any changes in your health. Sometimes the immune system will start to fight infections that were hidden in your body, such as pneumonia or tuberculosis. Autoimmune disorders (eg, Graves' disease, polymyositis, or Guillain-Barré syndrome) may also occur.
This medicine may decrease or lose body fat, especially in your face, arms, legs, or buttocks, when this medicine is used for a long time. Talk to your doctor if you have concerns.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
