Table of contents:

Prezista is a medication used in the treatment of HIV-1 infection in combination with other antiretroviral agents. It contains the active ingredient darunavir, which is a type of protease inhibitor. Protease inhibitors are a class of drugs used to treat HIV (Human Immunodeficiency Virus) by blocking an enzyme involved in the replication of the virus.

Prezista is typically administered in combination with ritonavir, which helps to increase the concentration of darunavir in the blood. Darunavir helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life.

Uses and Dosage

Prezista (Darunavir) is available as a tablet to be taken orally with food, as directed by your doctor. It needs to be taken in combination with other medications, typically once or twice a day. Prezista (darunavir) should be taken as a whole tablet without crushing or chawing.

The dosage of Prezista is determined based on factors such as age, medical history, and response to treatment. If you are a child, your body weight will also be considered. To use Prezista (Darunavir) tablets, the typical starting dose for adults is 800 mg once daily with ritonavir 100 mg, both of which must be taken with food. This is taken in combination with other medications, once or twice a day.

Take Prezista exactly as prescribed by your doctor; this will ensure that you are receiving the best possible treatment for your condition. For the best results, take Prezista at the same time(s) every day.

Do not alter the dosage, skip doses, or stop taking the medication (or any other HIV medications) even for a brief period without your doctor's approval. Doing so may lead to an increase in the amount of virus in your body, make the infection more difficult to treat, or worsen side effects associated with the medication.
