What should I know about adefovir dipivoxil before taking it?

Before taking adefovir, you should know that some people get a very serious recurrence of the hepatitis infections once they stop taking adefovir. Because of this it's important to follow your doctor's dosage instructions very carefully, and to get regular blood tests once you stop taking adefovir to make sure your infection isn't getting worse. If you have HIV that's not being treated, adefovir also may increase the chance that you won't be able to treat the HIV infection with normal HIV medications. To reduce this risk, you should be tested for HIV before taking adefovir so you can start treatment if necessary. Adefovir may also increase your risk for a condition called lactic acidosis, which is a buildup of lactic acid in the blood that can become life-threatening. See your doctor right away if you develop symptoms like difficulty breathing, irregular heartbeat, unusual weakness or muscle pain, dizziness and stomach pain with nausea and vomiting. Adefovir may increase the risk for serious kidney or liver problems, as well. The kidney problems usually occur in people who had pre-existing kidney issues, so talk to your doctor before taking adefovir if you have existing kidney problems. If you develop symptoms of liver problems, such as change in color of urine or stools, stomach pain or nausea, loss of appetite or yellowing of the skin and eyes, talk to your doctor.
