What is Darunavir (Prezista) Used For? Side Effects and Dosage

What is Darunavir (Prezista)?

Darunavir is an antiretroviral drug that is sold under the brand name Prezista. It is used in combination with other HIV therapy medications and is classified as a protease inhibitor drug. Prezista is manufactured by Janssen Therapeutics, a division of Janssen Products.

What is This Medication Used For?

Prezista is used with other antiretroviral medications to treat HIV. Though there is currently no cure for HIV, antiretroviral therapy (ART) helps reduce the spread of HIV within the blood. As a protease inhibitor, Darunavir interferes with the enzyme protease. Protease is used by HIV-infected cells to make copies of the virus and spread it throughout the body. When the enzyme is inhibited, it slows or stops the spread of new viruses. 

How to Take Prezista

Prezista medication comes in oval tablets that are taken orally. To ensure that the drug is absorbed, Darunavir must be taken with food. If you forget a dosage and realize your mistake within 12 hours, take Darunavir immediately. If you forget a dose and notice after 12 hours or more have passed, wait for the next dosage and take it at the usual time. Do not take two doses at the same time.
