Questions About Esbriet® (pirfenidone)

See answers to some commonly asked questions about Esbriet

Esbriet is a prescription medicine used to treat people with a lung disease called idiopathic pulmonary fibrosis (IPF).

IPF is different from other interstitial lung diseases (ILD), or diseases that cause inflammation and scarring of the lungs. Esbriet is specifically studied and approved for use in IPF, which is a certain type of ILD.

It is not known if Esbriet is safe and effective in children.

No, Esbriet is not approved to treat other ILDs. Esbriet is specifically studied and approved for use in IPF, which is a certain type of ILD. IPF is different from other ILDs, or diseases that cause inflammation and scarring of the lungs.

Although lung function that is lost cannot be restored, treatment may help maintain more of your lung function by slowing the progression of the disease. This treatment may also cause side effects.

In a 1-year clinical study, people who took Esbriet had better breathing capacity compared with those who did not take Esbriet (193 mL difference in forced vital capacity [FVC]). Patients taking Esbriet had an average decline of 235 mL in FVC compared with a 428 mL decline for patients who did not take Esbriet.

One 72-week study showed similar results. Another 72-week study did not show a significant difference between people who took Esbriet and those who did not.

At the end of a 1-year clinical study of people with IPF, more than twice as many people who took Esbriet preserved baseline lung function compared to those who did not take Esbriet.

  • With Esbriet, 23% of people had stable lung function
  • Without Esbriet, 10% of people had stable lung function
  • One 72-week study showed similar results. Another 72-week study did not show a significant difference between people who took Esbriet and those who did not

In the clinical studies of Esbriet, some side effects occurred soon after starting treatment and/or decreased over time:

  • Sensitivity to sunlight. The majority of these reactions in clinical studies happened in the first 6 months on treatment. 9% of patients treated with Esbriet experienced sun sensitivity (vs 1% not taking Esbriet)
  • Severe skin reactions. Call your doctor right away if you have a severe skin reaction such as skin blisters, rash, sores in the mouth, hives or any other severe skin symptoms.
  • Stomach problems. These were most often experienced early in the course of treatment—mostly in the first 3 months—and decreased over time. 2.2% of patients had to stop taking Esbriet because of stomach problems (vs 1% not taking Esbriet)

These are not the only side effects. Be sure to talk to your healthcare provider immediately if you experience any side effects.

Managing Esbriet Side Effects

See How to Take Esbriet to learn about the dosing schedule and starting treatment.

Esbriet dosing is intended to allow your body to gradually adjust to the medicine.

You should always take Esbriet with food. Doing so may help reduce certain side effects, including dizziness or nausea. Taking Esbriet with food decreases how quickly Esbriet is absorbed. It also decreases the drug level of Esbriet in the blood.

IPF is progressive, and once damage occurs, it cannot be undone. It is also unpredictable: there is no way to know when your IPF will begin to get worse. Since IPF is progressive, irreversible, and unpredictable, it is important to talk to your doctor about IPF treatment today. There is no way to undo the damage caused by IPF. However, Esbriet may help preserve more lung function by slowing disease progression. Talk to your doctor about Esbriet.

Esbriet may cause serious side effects, including liver problems, sun sensitivity, severe skin reactions and stomach problems. Use the tips below to help manage and prevent certain side effects, or 

Read more about managing side effects >

Preventing sun sensitivity

  • Always use a broad-spectrum (UVA/UVB) sunscreen with SPF 50 or higher when outside. Reapply often throughout the day
  • Avoid taking other medicines that can make your skin sensitive to the sun, the light from sunlamps, and tanning beds
  • Minimize exposure to sunlight. Wear a hat and clothing that protect your skin, including your face, arms, and legs

Managing nausea and dizziness

  • Always take Esbriet with food, as doing so may reduce side effects such as nausea and dizziness

Tell your doctor immediately if you have any side effects while you are taking Esbriet. He or she may need to reduce your dose of Esbriet or ask you to stop taking it for a short time to help manage side effects.
