Summary
Darunavir is used to treat HIV infection, which is a virus that attacks the immune system. It helps control the virus and improves immune function when used with other HIV medications.
Darunavir works by blocking a protein called protease, which the HIV virus needs to multiply. This helps reduce the amount of virus in the body and boosts the immune system.
The usual starting dose for adults is 800 mg once daily with food. It's important to follow your doctor's instructions, as doses may vary based on individual health needs.
Common side effects include nausea, diarrhea, and headache. These effects can vary in frequency and severity among individuals.
Darunavir can cause liver problems, so regular liver tests are recommended. It should not be used by people with severe liver issues. Always inform your doctor about other medications to avoid interactions.

If you miss a dose, take it as soon as you remember unless it's almost time for your next dose. In that case, skip the missed dose and continue your regular schedule. Never take two doses at once. Always follow your doctor's specific advice about diet and fluid intake while taking this medication.
How long does it take for Darunavir to start working?
Darunavir begins working in your body shortly after you take it, but it may take several weeks to see significant changes in your viral load. The full therapeutic effect can take a few months. How quickly the medication works can depend on your overall health and adherence to the treatment plan.

Is Darunavir addictive?

Is it safe to drink alcohol while taking Darunavir?
