Summary
Nelfinavir is used to treat HIV infection, which is a virus that attacks the immune system. It helps reduce the amount of virus in the body and improves immune function.
Nelfinavir works by blocking the protease enzyme, which is needed by HIV to replicate. This action helps lower the viral load, which is the amount of virus in the body, and boosts immune function.
The usual starting dose for adults is 1250 mg taken twice daily with food. Taking it with food improves absorption, which means how well the body takes in the medication.
Common side effects of Nelfinavir include diarrhea, which is frequent loose stools, nausea, which is feeling sick to your stomach, and abdominal pain, which is discomfort in the belly area.
Nelfinavir should not be used by those allergic to it or its ingredients. It can interact with certain drugs like rifampin, which can reduce its effectiveness. Caution is needed for patients with liver problems.
