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 gums. Check with your medical doctor or dentist if you have any questions about proper oral hygiene (mouth care) during treatment.
Zidovudine may cause some serious side effects, including bone marrow problems. Symptoms of bone marrow problems include fever, chills, or sore throat; pale skin; and unusual tiredness or weakness. These problems may require blood transfusions or temporarily stopping treatment with zidovudine. Check with your doctor if any new health problems or symptoms occur while you or your child are taking zidovudine.
HIV may be acquired from or spread to other people through infected body fluids, including blood, vaginal fluid, or semen. If you are infected, it is best to avoid any sexual activity involving an exchange of body fluids with other people. If you do have sex, always wear (or have your partner wear) a condom (“rubber”). Only use condoms made of latex, and use them every time you have vaginal, anal, or oral sex. The use of a spermicide (such as nonoxynol-9) may also help prevent the spread of HIV if it is not irritating to the vagina, rectum, or mouth. Spermicides have been shown to kill HIV in lab tests. Do not use oil-based jelly, cold cream, baby oil, or shortening as a lubricant—these products can cause the condom to break. Lubricants without oil, such as K-Y Jelly, are recommended. Women may wish to carry their own condoms. Birth control pills and diaphragms will help protect against pregnancy, but they will not prevent someone from giving or getting the AIDS virus. If you inject drugs, get help to stop. Do not share needles with anyone. In some cities, more than half of the drug users are infected, and sharing even one needle can spread the virus. If you have any questions about this, check with your doctor.
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.
When you or your child start taking HIV medicines, your immune system may get stronger. If you have infections that are hidden in your body (e.g., pneumonia or tuberculosis), you may notice new symptoms when your body tries to fight them. If this occurs, tell your doctor right away.
This medicine may cause you or your child to have excess body fat. Tell your doctor right away if you notice changes in your body shape, including an increased amount of body fat in the neck or upper back, face, around the chest, or stomach area. You might also lose fat from your legs, arms, or face.
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.
