What is Retrovir?

See also: Atripla

Retrovir is an antiviral medicine that prevents human immunodeficiency virus (HIV) from multiplying in your body.

Retrovir is used to treat HIV, the virus that can cause acquired immunodeficiency syndrome (AIDS). This medicine is also given during pregnancy to prevent an HIV-infected woman from passing the virus to her baby. This medicine is not a cure for HIV or AIDS.

Retrovir may also be used for purposes not listed in this medication guide.

Important Information

Retrovir may cause a serious condition called lactic acidosis. Get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, irregular heart rate, dizziness, or feeling very weak or tired.

Retrovir can lower blood cells that help your body fight infections and help circulate oxygen in your body. This medicine can also cause severe or life-threatening effects on your liver.

Call your doctor if you have symptoms such as: fever, flu symptoms, unusual tiredness, mouth sores, pale skin, cold hands and feet, upper stomach pain, dark urine, or jaundice (yellowing of the skin or eyes).

Before taking this medicine

Do not take Retrovir if you have ever had an allergic reaction to Retrovir or any medicine that contains this medicine, including Combivir or Trizivir.

Do not take Retrovir with any other medicine that contains Retrovir or stavudine, including: Combivir, Trizivir, or Zerit.

Some people taking Retrovir develop a serious condition called lactic acidosis. This may be more likely in women, in people who are overweight or have liver disease, and in people who have taken HIV/AIDS medication for a long time. Talk with your doctor about your risk.

Retrovir can also cause severe or life-threatening effects on your liver. Tell your doctor if you have liver disease, especially hepatitis C.

To make sure Retrovir is safe for you, tell your doctor if you have ever had:

  • kidney disease;

  • muscle problems;

  • bone marrow suppression;

  • bleeding or a blood cell disorder; or

  • if you drink large amounts of alcohol.

Retrovir is not expected to harm an unborn baby. However, HIV can be passed to your baby if you are not properly treated during pregnancy. Take all of your HIV medicines as directed to control your infection.

If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of zidovudine on the baby.

Women with HIV or AIDS should not breast feed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.

How should I take Retrovir?

Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use Retrovir in larger or smaller amounts or for longer than recommended.

Retrovir can be taken with or without food.

If a child is using this medicine, tell your doctor if the child has any changes in weight. Retrovir doses are based on weight in children, and any changes may affect your child's dose.

Retrovir can lower blood cells that help your body fight infections and help circulate oxygen in your body. You may get an infection or feel more tired than usual. Your blood will need to be tested often.

HIV/AIDS is usually treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice. Every person with HIV or AIDS should remain under the care of a doctor.

Store at room temperature away from moisture and heat.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking Retrovir?

Avoid drinking alcohol. It may increase your risk of liver damage or lactic acidosis.

Taking Retrovir will not prevent you from passing HIV to other people. Do not have unprotected sex or share razors or toothbrushes. Talk with your doctor about safe ways to prevent HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person.

Retrovir side effects

Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).

Early symptoms of lactic acidosis may get worse over time and this condition can be fatal. Get emergency medical help if you have even mild symptoms: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, irregular heart rate, dizziness, or feeling very weak or tired.
