Stavudine can cause serious, life-threatening side effects. These include lactic acidosis (buildup of lactic acid in the blood), liver problems, and pancreatitis (inflammation of the pancreas).
The risk of lactic acidosis may be higher if you have liver problems, are female, are pregnant, are overweight, or have been treated for a long time with other HIV medicines. Some pregnant women who were taking both stavudine and didanosine (another HIV medicine) died after developing lactic acidosis. For more information about lactic acidosis and its risk factors, read the AIDS_info_ fact sheet on HIV and lactic acidosis.
Contact your health care provider right away if you have any of the following symptoms that could be signs of lactic acidosis:
- Feeling weak or tired
- Unusual muscle pain
- Trouble breathing
- Stomach pain with nausea and vomiting
- Feeling cold, especially in your arms and legs
- Feeling dizzy or lightheaded
- Fast or irregular heartbeat
Contact your health care provider right away if you have any of the following symptoms that could be signs of liver problems:
- Yellowing of your skin or the whites of your eyes (jaundice).
- Dark-colored urine
- Pain on the right side of your stomach
- Swelling of your stomach
- Easy bruising or bleeding
- Loss of appetite
Contact your health care provider right away if you have any of the following symptoms that could be signs of pancreatitis:
- Stomach pain
- Swelling of your stomach
While taking stavudine, it is important to keep all of your appointments with your health care provider.
What Is Stavudine?
Stavudine is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults, children, and infants. Stavudine is always used in combination with other HIV medicines.
Stavudine belongs to a class (group) of HIV drugs called nucleoside reverse transcriptase inhibitors (NRTIs). NRTIs block an HIV enzyme called reverse transcriptase. (An enzyme is a protein that starts or increases the speed of a chemical reaction.) By blocking reverse transcriptase, NRTIs prevent HIV from multiplying and can reduce the amount of HIV in the body.
HIV medicines can't cure HIV/AIDS, but taking a combination of HIV medicines (called an HIV regimen) every day helps people with HIV live longer, healthier lives. HIV medicines also reduce the risk of HIV transmission. If you are taking HIV medicines, including stavudine, don't cut down on, skip, or stop taking them unless your health care provider tells you to.
What Should I Tell My Health Care Provider Before Taking Stavudine?
Before taking stavudine, tell your health care provider:
- If you are allergic to stavudine or any other medicines.
- If you have or have ever had liver problems (such as hepatitis).
- If you have or had problems with your pancreas (such as pancreatitis).
- If you have or have ever had kidney problems.
- If you have or had persistent numbness, tingling, or pain in the hands or feet (neuropathy).
- If you have gallstones.
- If you have diabetes.
- If you have any other medical conditions.
- If you drink alcoholic beverages.
- If you are using hormone-based birth control (such as pills, implants, or vaginal rings). For more information about using birth control and HIV medicines at the same time, view the AIDSinfo HIV and Birth Control infographic.
- If you are pregnant or plan to become pregnant. Whether stavudine can harm an unborn baby is unknown. The combination of stavudine and didanosine (another HIV medicine) should be used with caution during pregnancy and is recommended only if the potential benefit clearly outweighs the potential risk. Tell your healthcare provider right away if you become pregnant while taking stavudine. You and your healthcare provider will decide if you should continue taking stavudine while you are pregnant.
- If you are breastfeeding or plan to breastfeed. Do not breastfeed if you have HIV or are taking stavudine.
- About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Especially tell your doctor if you take any of the following medicines: zidovudine (brand name: Trizivir), didanosine (brand name: Videx), doxorubicin, ribavirin, interferon, or hydroxyurea. Stavudine may affect the way other medicines or products work, and other medicines or products may affect how stavudine works. Taking stavudine together with certain medicines or products may cause serious, life-threatening side effects.
How Should I Take Stavudine?
Stavudine (brand name: Zerit) comes in capsule form in the following strengths:
- 15-mg capsules
- 20-mg capsules
- 30-mg capsules
- 40-mg capsules
Stavudine also comes as a 1-mg/mL oral solution for those who have trouble swallowing capsules. A pharmacist prepares the stavudine oral solution by mixing stavudine powder with purified water.
Take stavudine according to your health care provider's instructions.
Take stavudine with or without food.
Avoid drinking alcohol while taking stavudine. Alcohol may increase your risk of pancreatitis (pain and swelling of your pancreas) or liver damage.
When giving stavudine oral solution to a child, shake the bottle well before measuring each dose.
Always take stavudine in combination with other HIV medicines.
If you take too much stavudine, contact your health care provider or local poison control center (1-800-222-1222) right away, or go to the nearest hospital emergency room.
For more information on how to take stavudine, see the FDA drug label from DailyMed. (DailyMed is a federal website that includes the most recent drug labels submitted to FDA.)
What Should I Do If I Forget a Dose?
If you miss a dose of stavudine, take the missed dose as soon as you remember it. But if it is almost time for your next dose, skip the missed dose and just take your next dose at the regular time. Do not take two doses at the same time to make up for a missed dose.
What Side Effects Can Stavudine Cause?
Stavudine may cause side effects. Many side effects from HIV medicines, such as nausea or occasional dizziness, are manageable. See the AIDS_info_ fact sheet on HIV Medicines and Side Effects for more information.
Some side effects of stavudine can be serious. Serious side effects of stavudine include a buildup of lactic acid in the blood (lactic acidosis), liver problems, and inflammation of the pancreas (pancreatitis). (See the WARNING box above.)
Other possible side effects of stavudine include:
- Neurologic symptoms (signs that stavudine may be affecting the nerves). Tell your health care provider right away if you have any numbness or tingling in your hands or feet or weakness in your arms, legs, hands, or feet. It may be difficult to recognize neurologic symptoms in children who take stavudine. Ask your child's healthcare provider for the signs and symptoms of this side effect in children.
- Changes in body fat (including gain or loss of fat).
- Changes in your immune system (called immune reconstitution inflammatory syndrome or IRIS). IRIS is a condition that sometimes occurs when the immune system begins to recover after treatment with an HIV medicine. As the immune system gets stronger, it may have an increased response to a previously hidden infection.
Tell your health care provider if you have any side effect that bothers you or that does not go away.
These are not all the possible side effects of stavudine. To learn more about possible side effects of stavudine, read the drug label or package insert or talk to your health care provider or pharmacist.
You can also report side effects to FDA at 1-800-FDA-1088 (1-800-332-1088) or online at https://www.accessdata.fda.gov/scripts/medwatch/.
