Is pirfenidone available as a generic medication?
Yes. Pirfenidone is the active ingredient sold under brand names for idiopathic pulmonary fibrosis (IPF), and multiple generic versions have entered the market in different countries over time. Availability depends on your location and the specific product strength and formulation.
What is pirfenidone used for?
Pirfenidone is used to treat idiopathic pulmonary fibrosis (IPF). Patients and prescribers look for the same active ingredient (pirfenidone) when switching between brand and generic products.
Do generic pirfenidone tablets or capsules have to match the brand?
In general, generic drugs are expected to be equivalent to the brand in terms of active ingredient and performance (for example, how the drug is absorbed). If you’re switching, it matters whether your prescription is for the exact strength and dosing schedule that matches the product you receive.
How do I find the right generic pirfenidone for my prescription?
To get the correct generic, check the label for:
- The active ingredient: pirfenidone
- The strength (mg)
- The dosage form (for example, tablets vs capsules)
- The dosing schedule written by your clinician
If you share your country and the exact strength on your prescription (e.g., 200 mg vs 267 mg), I can help narrow down what to search for.
