Prezcobix?

Prezcobix is a prescription HIV medicine that combines two drugs in one tablet:

- Darunavir: a protease inhibitor that fights HIV-1
- Cobicistat: a pharmacokinetic booster that helps increase darunavir levels

Key points:
- Use: For treatment of HIV-1 infection in adults and certain pediatric patients, in combination with other antiretroviral meds.
- Dose (usual): One tablet once daily with food (darunavir 800 mg / cobicistat 150 mg). Your clinician may adjust the regimen based on your history.
- How to take: Take exactly as prescribed. Take with food to help absorption. Do not crush or chew the tablet.
- Safety and interactions: Cobicistat inhibits CYP3A4, leading to many drug interactions. Tell your healthcare provider about all medicines and supplements you take (prescription, OTC, vitamins, herbal products like St. John’s wort). Some drugs must not be used with Prezcobix (e.g., rifampin; certain anticonvulsants; some statins). Your clinician can review interactions.
- Common side effects: Diarrhea, nausea, vomiting, headache, and rash. Others can include fatigue, abdominal pain, or liver-related effects. Serious liver problems and kidney function changes can occur; contact a clinician if you notice symptoms like yellowing of the skin/eyes, dark urine, persistent nausea/vomiting, severe upper stomach pain, or unusual bleeding/bruising.
- Pregnancy and breastfeeding: Discuss with your clinician; you’ll weigh benefits and risks.
- Additional notes: This is part of a combination antiretroviral regimen. It does not cure HIV, but helps control the virus when used with other meds.

If you have a specific question (like dosing for a certain situation, drug interactions with another medication you’re taking, or side effects you’re experiencing), tell me more and I can tailor the info. If this is for a current patient, please consult the prescribing clinician or the package insert for exact instructions.
