Are there any serious side effects of Pirfenidone/Axri?

Pirfenidone/Pirfenidone is an oral drug used to treat idiopathic pulmonary fibrosis (IPF). Although it has shown positive effects in delaying disease progression and improving patients' quality of life, its side effects have also attracted widespread concern. For many patients, it is important to understand the nature and management of these side effects.

First, nausea is one of the most common side effects of pirfenidone. Many patients experience nausea during the initial stages of medication, and this feeling is often related to the gastrointestinal reaction to the medication. To alleviate this discomfort, doctors often recommend that patients take the medication after a meal, as this can help reduce gastrointestinal irritation and improve drug tolerance. In addition, some patients may experience vomiting and indigestion (such as heartburn), which are also closely related to how the drug is taken.

Another significant side effect is rash, and many patients experience skin reactions after taking pirfenidone. The rash usually manifests as erythema or itching, and although most cases are mild, some patients may experience more severe skin reactions. In this case, the patient should communicate with the doctor in time and consider adjusting the dosage of medication or taking other treatment measures if necessary.

Diarrhea is also a side effect of pirfenidone, and patients may experience mild to moderate diarrhea. For this reason, your doctor may recommend some dietary changes or the use of some gut-friendly medications to reduce this symptom. In addition, loss of appetite is also common among patients, which may further affect the patient's nutritional status and physical recovery.

In addition, photosensitivity is also a specific side effect of pirfenidone. Patients may have increased sensitivity to sunlight during treatment and may experience sunburn-like reactions when exposed to sunlight. Therefore, patients should pay attention to sun protection in daily life and avoid prolonged exposure to strong light.
