How do I take Nelfinavir?

Nelfinavir (Viracept) is a drug used to treat the human immunodeficiency virus (HIV), the virus responsible for acquired immunodeficiency syndrome (AIDS). It belongs to a class of drugs called protease inhibitors. Although it will not cure HIV, if taken consistently, as directed by your doctor, it can slow the spread of the virus in the body and reduce complications.

Nelfinavir comes in tablet form that is taken by mouth with food. It also comes in a powder, which is helpful if you are having trouble swallowing pills. Take it with a glass of water, milk, soymilk or a liquid nutritional supplement. It is usually taken two to three times a day. If you use the powder, refill the glass with more water to get the entire dose that may still be in the glass. Don't take it with acidic foods or orange juice, apple juice or applesauce. 

The dose of nelfinavir depends on how much you weigh and your age and varies from person to person.

Typical adult dose:
  • 1250 mg. (either five 250 mg. tablets or two 625 mg. tablets), taken twice a day
  • 750 mg., (three 250 mg. tablets), three times a day
Since you will also be taking other drugs for HIV, talk to your pharmacist about the timing of each one. For example, if you are also taking didanosine (Videx), you will need to take it one hour before or more than two hours after your nelfinavir. It is important for you alert your pharmacist of all of the prescription, over-the-counter remedies and dietary supplements you are taking to see if there are any worrisome combinations.
