Taking PIFELTRO

PIFELTRO is a once daily pill. You and your doctor can decide if PIFELTRO could be right for you.

Your health and HIV-1

Whether you take over-the-counter or doctor-prescribed medicines for other conditions, it is important that you talk to your doctor about all of your medicines.

PIFELTRO can be taken with a wide range of common, non-HIV-1 medicines, such as:

  • Proton pump inhibitors for heartburn (pantoprazole)
  • Oral contraceptives for birth control (ethinyl estradiol and levonorgestrel)
  • Methadone for pain management
  • Statins for high cholesterol (atorvastatin)
  • Metformin for diabetes (metformin hydrochloride)

Important

Do not take PIFELTRO if you are taking one of the following medicines: carbamazepine, oxcarbazepine, phenobarbital, phenytoin, enzalutamide, rifampin, rifapentine, mitotane, St. John’s wort. Ask your doctor or pharmacist if you are not sure if your medicine is one that is listed above. If you have taken any of the medicines in the past 4 weeks, talk to your doctor or pharmacist before starting PIFELTRO.

How to take PIFELTRO

  • Take PIFELTRO every day exactly as your doctor tells you to take it. Take PIFELTRO 1 time each day, at about the same time every day.
  • Tell your doctor if you have taken rifabutin in the past 4 weeks.
