Nelfinavir — Uses, Dosage, Side Effects & Safety

Drug class: Antiretroviral (Protease Inhibitor)

Overview

Nelfinavir is an antiretroviral medication used to treat human immunodeficiency virus (HIV) infection in adults and children. It is typically prescribed as part of combination therapy with other antiretroviral agents to help control HIV and improve immune function. Nelfinavir works by blocking the action of HIV protease, an enzyme the virus needs to multiply. By inhibiting this enzyme, nelfinavir reduces the amount of HIV in the body, helping to slow the progression of the disease and lower the risk of developing acquired immunodeficiency syndrome (AIDS). Key points for patients: Nelfinavir does not cure HIV or AIDS, but it helps manage the infection when taken consistently as prescribed. It is important to take nelfinavir exactly as directed, without missing doses, to prevent the virus from becoming resistant to treatment.
