What is Pifeltro (doravirine) used for?
Pifeltro is a prescription medicine used to treat HIV-1 infection in adults. It’s taken as part of an antiretroviral combination regimen rather than by itself.
How does Pifeltro work?
Pifeltro’s active ingredient is doravirine, which blocks the HIV reverse transcriptase enzyme. Specifically, it’s a non-nucleoside reverse transcriptase inhibitor (NNRTI). By interfering with HIV replication, it helps lower the amount of virus in the body.
How is Pifeltro taken?
Pifeltro is taken by mouth, typically once daily (standard adult dosing). Your prescriber’s instructions are important because dosing can depend on other medications you’re also taking.
What side effects do people ask about?
Commonly reported side effects can include headache, nausea, diarrhea, and dizziness. If you have symptoms that worry you, or any severe or persistent reaction, contact your clinician promptly.
What drug interactions should patients watch for?
HIV regimens can be affected by other medicines, especially drugs that change liver enzymes involved in doravirine levels. If you start, stop, or change any medication (including antibiotics, seizure meds, tuberculosis treatments, or supplements), ask a pharmacist or prescriber to check interactions.
Can it be used with other HIV medicines?
Yes. Pifeltro is designed to be used with other antiretroviral drugs in a combination strategy. The exact combination matters for effectiveness and resistance prevention.

What to do if you miss a dose
HIV medicines work best when taken consistently. If you miss a dose, follow the instructions in your medication guide or ask your pharmacist what to do based on how late the missed dose is.
Who should not take Pifeltro without medical guidance?
Anyone with significant medication interactions, prior treatment issues, or specific health conditions should discuss suitability with their clinician. Because HIV care depends on resistance history and the rest of your regimen, decisions shouldn’t be made based on general information alone.
If you tell me your goal (for example, “what is it for,” “side effects,” “interactions with my meds,” or “is there a generic”), I can tailor the answer to that.
