Adefovir

Do not stop taking adefovir without talking to your doctor. When you stop taking adefovir your hepatitis may get worse. This is most likely to happen during the first 3 months after you stop taking adefovir. Be careful not to miss doses or run out of adefovir. Tell your doctor if you have or have ever had liver disease other than hepatitis B or cirrhosis (scarring of the liver). If you experience any of the following symptoms after you stop taking adefovir, call your doctor immediately: extreme tiredness, weakness, nausea, vomiting, loss of appetite, yellowing of the skin or eyes, dark-colored urine, light-colored bowel movements, and muscle or joint pain.

Adefovir may cause kidney damage. Tell your doctor if you have or have ever had kidney disease, high blood pressure, or diabetes. Tell your doctor and pharmacist if you are taking or have ever taken any of the following medications: aminoglycoside antibiotics such as amikacin, gentamicin, kanamycin, neomycin, streptomycin, and tobramycin (Tobi,); aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin) and naproxen (Aleve, Naprosyn); cyclosporine (Gengraf, Neoral, Sandimmune); tacrolimus (Prograf); or vancomycin. If you experience any of the following symptoms, call your doctor immediately: confusion; decreased urination; or swelling of the hands, feet, ankles, or lower legs.

If you have HIV or AIDS that is not being treated with medications and you take adefovir, your HIV infection may become difficult to treat. Tell your doctor if you have HIV or AIDS or if you have unprotected sex with more than one partner or use injectable street drugs. Your doctor may test you for HIV infection before you begin treatment with adefovir and at any time during your treatment when there is a chance that you were exposed to HIV.

Adefovir, when used alone or in combination with other antiviral medications, can cause serious or life-threatening damage to the liver and a condition called lactic acidosis (a build-up of acid in the blood). The risk that you will develop lactic acidosis may be higher if you are a woman, if you are overweight, or if you have been treated with medications for hepatitis B virus (HBV) infection for a long time. Tell your doctor if you have or have ever had liver disease. If you experience any of the following symptoms, call your doctor immediately: confusion; unusual bleeding or bruising; yellowing of the skin or eyes; dark-colored urine; light-colored bowel movements; difficulty breathing; stomach pain or swelling; nausea; vomiting; unusual muscle pain; loss of appetite for at least a few days; lack of energy; flu-like symptoms; itching; feeling cold, especially in the arms or legs; dizziness or lightheadedness; fast or irregular heartbeat; or extreme weakness or tiredness.

Keep all appointments with your doctor and the laboratory before, during, and for a few months after your treatment with adefovir. Your doctor will order certain lab tests to check your body’s response to adefovir during this time.

🔔 Why is this medication prescribed?

Adefovir is used to treat chronic (long-term) hepatitis B infection (swelling of the liver caused by a virus) in adults and children 12 years of age and older. Adefovir is in a class of medications called nucleotide analogs. It works by decreasing the amount of hepatitis B virus (HBV) in the body. Adefovir will not cure hepatitis B and may not prevent complications of chronic hepatitis B such as cirrhosis of the liver or liver cancer. Adefovir may not prevent the spread of hepatitis B to other people.

🔔 How should this medicine be used?

Adefovir comes as a tablet to take by mouth. It is usually taken once a day with or without food. Take adefovir at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take adefovir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
