Pirfenex 200 mg Tablet

Pirfenex 200 mg Tablet is a prescription tablet that contains 200 mg of pirfenidone in each tablet. Pirfenidone is an antifibrotic medicine, not an asthma reliever, and it is used to help slow the progression of idiopathic pulmonary fibrosis (IPF), a long-term lung disease that causes scarring and makes breathing harder. Pirfenex 200 mg Tablet is taken by mouth and is usually part of a scheduled treatment plan chosen by a doctor based on the patient’s condition and tolerance.

How it works: Pirfenidone helps reduce the activity of substances in the body that promote inflammation and scar tissue buildup in the lungs. In tablet form, Pirfenex 200 mg Tablet is swallowed and absorbed through the digestive system to help slow lung scarring over time.

Pirfenex 200 mg Tablet is a lower-strength tablet that can help doctors build up treatment gradually and tailor the dose to a person’s tolerance. Because pirfenidone often causes stomach upset, dizziness, or sun sensitivity, a doctor may choose the 200 mg tablet first or use it to adjust the total daily dose more precisely than with higher-strength tablets.

• Idiopathic pulmonary fibrosis (IPF)
• Slowing the progression of lung scarring
• Maintenance antifibrotic therapy as prescribed by a specialist

• Swallow Pirfenex 200 mg Tablet whole with water; do not crush, chew, or split it unless your doctor tells you to.
• Take it with food to help reduce stomach upset and nausea.
• Take it at the same times each day as prescribed to keep medicine levels steady.
• Follow the exact dose-escalation schedule your doctor gives you; the 200 mg tablet may be used to build up to a higher total daily dose.
• If you miss a dose, follow your prescriber’s instructions or the package directions; do not double up on your own.
• Limit sun exposure and use sunscreen/protective clothing, because pirfenidone can make your skin more sensitive to sunlight.

Each Pirfenex 200 mg Tablet provides 200 mg of pirfenidone. The exact number of tablets per day depends on the dose schedule your doctor prescribes; pirfenidone is often taken three times daily and the total daily amount is adjusted gradually, with a common target maximum of 2403 mg per day for adults when tolerated.

Do not change your dose or stop the medicine without speaking to your doctor.
