A low rate of side effects

In a 96-week study of adults who had never been on an HIV-1 treatment before, 364 adults received a PIFELTRO-based single-tablet regimen, while 364 adults received an Atripla once-daily tablet. In this study, fewer adults stopped taking a PIFELTRO-based single-tablet regimen than Atripla because of side effects.

97% of Participants in a 96-Week Study Continued Taking a PIFELTRO® (doravirine)-Based Single-Tablet Regimen

What are the most common side effects?

The most common side effects of PIFELTRO include:

  • nausea
  • dizziness
  • headache
  • tiredness
  • diarrhea
  • stomach (abdominal) pain
  • abnormal dreams

These are not all the possible side effects of PIFELTRO. Call your healthcare provider for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

7% of Participants in a 96-Week Study Experienced Dizziness While Taking a PIFELTRO® (doravirine)-Based Single-Tablet Regimen, 5% of Participants in a 96-Week Study Experienced Nausea While Taking a PIFELTRO® (doravirine)-Based Single-Tablet Regimen, 5% of Participants in a 96-Week Study Experienced Abnormal Dreams While Taking a PIFELTRO® (doravirine)-Based Single-Tablet Regimen

Changes in your immune system (immune reconstitution syndrome) can happen when you start taking HIV-1 medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider right away if you start having new symptoms after starting your HIV-1 medicine.

Your health and HIV-1

Staying undetectable

PIFELTRO, when taken as part of a multi-tablet regimen, can help you get your viral load to undetectable.

Undetectable means the level of HIV-1 in your blood is so low that lab tests can’t detect it.

And when your HIV-1 is under control, you can focus on your health and life goals beyond HIV-1.

Model living with HIV

In a 48-week study, adults living with HIV-1 who were undetectable on their current treatment regimen switched to a PIFELTRO-based single-tablet regimen either at the start of the study, or at week 24 of the study.

At the start of the study:

  • 447 adults switched to a PIFELTRO-based single-tablet regimen.
  • 91% of those adults stayed undetectable at week 48.

At week 24 of the study:

  • 209 adults switched to a PIFELTRO-based single-tablet regimen.
  • 95% of those adults were undetectable at week 24 before switching to a PIFELTRO-based single-tablet regimen.

At week 48 of the study:

  • 95% of those adults who switched to PIFELTRO-based single-tablet regimen at week 24 stayed undetectable at week 48.

PIFELTRO may not have these effects on all adults living with HIV-1.

More about this study:

Patients were undetectable (HIV-1 RNA <50 copies/mL) for at least 6 months before starting the trial and had no history of resistancea to the PIFELTRO-based single-tablet regimen. The current treatment regimens consisted of 2 nucleoside reverse transcriptase inhibitors (NRTIs) in combination with a protease inhibitor (PI) plus either ritonavir or cobicistat, elvitegravir plus cobicistat, or a non-nucleoside reverse transcriptase inhibitor (NNRTI) before switching to a PIFELTRO-based single-tablet regimen. Patients were assigned by chance to one of the two treatment groups in the study. Patients and their healthcare providers taking part in the study knew which group they were part of.

aResistance happens when the virus mutates and your medicine stops working.

About cholesterol

HIV-1 and/or treatments for HIV may have a negative impact on your “bad” cholesterol (LDL-C). In a 96-week study of adults who had never been on an HIV-1 treatment before, 320 adults received PIFELTRO as part of a treatment regimen and 311 adults received another treatment regimen.b

PIFELTRO, as part of a treatment regimen, did not raise “bad” cholesterol, while the other treatment regimen did.

The benefit of these changes has not been demonstrated.

Severe skin reactions have happened in people treated with PIFELTRO. Call your healthcare provider right away if you develop a rash during treatment with PIFELTRO. Stop taking PIFELTRO and get medical help right away if you develop a painful rash with any of the following symptoms: fever, blisters or sores in the mouth, blisters or peeling of the skin, or redness or swelling of the eyes (conjunctivitis).

 

Changes in your immune system (Immune Reconstitution Syndrome) can happen when you start taking HIV-1 medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider right away if you start having new symptoms after starting your HIV-1 medicine.

 

The most common side effects of PIFELTRO include: nausea, dizziness, headache, tiredness, diarrhea, stomach (abdominal) pain, and abnormal dreams.

 

These are not all the possible side effects of PIFELTRO. For more information, ask your healthcare provider or pharmacist.

 

Before starting PIFELTRO, tell your healthcare provider about all your medical conditions, including if you are pregnant or plan to become pregnant. It is not known if PIFELTRO can harm your unborn baby. Tell your healthcare provider if you are breastfeeding or plan to breastfeed. PIFELTRO may pass to your baby in your breast milk. HIV may pass to your baby through your breast milk if your baby does not have HIV.

 

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Some medicines interact with PIFELTRO. Keep a list of your medicines to show your healthcare provider and pharmacist. Tell your healthcare provider if you have taken rifabutin in the past 4 weeks. Do not start taking a new medicine without telling your healthcare provider. Your healthcare provider can tell you if it is safe to take PIFELTRO with those other medicines.

 

Take PIFELTRO every day exactly as your healthcare provider tells you to take it. Take PIFELTRO 1 time each day, at about the same time every day.

 

Tell your healthcare provider if you have taken rifabutin in the past 4 weeks.

 

If you take the medicine rifabutin during treatment with PIFELTRO, take PIFELTRO 2 times each day, about 12 hours apart, as prescribed by your healthcare provider. You may not have enough doravirine in your blood if you take rifabutin during treatment with PIFELTRO.

 

Do not change your dose or stop taking PIFELTRO without talking to your healthcare provider. Stay under a healthcare provider’s care when taking PIFELTRO.

 

Take PIFELTRO on a regular dosing schedule as instructed by your healthcare provider. Do not miss doses.

 

If you miss a dose of PIFELTRO, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the next dose at your regular time. Do not take 2 doses of PIFELTRO at the same time.

 

Get your PIFELTRO refilled from your healthcare provider or pharmacy before you run out.

 

When your PIFELTRO supply starts to run low, get more from your healthcare provider or pharmacy. This is very important because the amount of virus in your blood may increase if the medicine is stopped for even a short time. The virus may develop resistance to PIFELTRO and become harder to treat.

 

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit fda.gov/medwatch, or call 1-800-FDA-1088.

 

Please read the accompanying Patient Information for PIFELTRO and discuss it with your healthcare provider. The physician Prescribing Information also is available.
