Darunavir is an HIV protease inhibitor used with other antiretroviral drugs to keep viral load low. Doctors usually prescribe it with a booster drug (ritonavir or cobicistat) so darunavir stays in your body longer. Take it with food — that helps your body absorb the medicine better.
Typical dosing for most adults is 800 mg once daily with a booster. If someone has prior resistance to protease inhibitors, prescribers may use 600 mg twice daily with a booster. Don’t change the dose or stop taking darunavir without talking to your clinic — missing doses can lead to resistance and fewer treatment options later.
Some people get diarrhea, nausea, stomach discomfort, headache, or rash. Darunavir can also affect liver enzymes, blood sugar, and cholesterol. If you have hepatitis B or C or a history of liver disease, your provider will check liver tests regularly. Watch for signs of serious rash, jaundice, dark urine, or unexplained tiredness and report these right away.
Darunavir interacts with many drugs because it affects the CYP3A enzyme system. That means some medicines can raise darunavir levels and others can make it much less effective. Avoid using simvastatin or lovastatin with darunavir — your doctor will pick safer options for cholesterol. Strong enzyme inducers like rifampin or St. John’s wort can lower darunavir and risk treatment failure. Tell your provider and your pharmacist that you take darunavir so they can check interactions before adding medicines.
Pregnancy, breastfeeding, and other conditions need a talk with your specialist. Some boosted regimens are used in pregnancy, but your care team will adjust doses and monitor both you and the baby. If you plan to get pregnant or are breastfeeding, bring this up early so you get the right plan.
How to make darunavir work best: take it at the same time every day with food, never skip doses, and use a booster as prescribed. Keep routine blood tests and clinic visits so your viral load and labs stay under control. Use a pill box, alarm, or phone reminder if you have trouble remembering doses.
If you experience severe side effects or suspect a drug interaction, contact your clinic or pharmacist right away. Never double up doses if you miss one — ask your provider what to do. For questions about cost, delivery, or getting refills from an online pharmacy, check trusted pharmacy resources and verify licensing and reviews before ordering.
