What special precautions should I follow?  

Before taking adefovir,

• tell your doctor and pharmacist if you are allergic to adefovir or any other medications.
• tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention the medications listed in the IMPORTANT WARNING section and probenecid. Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Do not take any other medications while you are taking adefovir unless your doctor has told you that you should.
• do not take adefovir if you are pregnant or plan to become pregnant. If you become pregnant while taking adefovir, call your doctor. Do not breast-feed while taking adefovir.
• if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking adefovir.

What special dietary instructions should I follow?  

Unless your doctor tells you otherwise, continue your normal diet.

What should I do if I forget a dose?  

If you remember the missed dose on the day that you were supposed to take it, take the missed dose as soon as you remember it. However, if you do not remember the missed dose until the next day, skip the missed dose and continue your regular dosing schedule. Do not take more than one dose of adefovir on the same day. Do not take a double dose to make up for a missed one.
