Can I take Pirfenidone for 3 months and stop for one month?

Pirfenidone (Pirfenidone, also known as Esbriet, is an anti-fibrotic drug that has been shown to slow the progression of idiopathic pulmonary fibrosis (IPF). It does not cure the condition or reverse any existing scarring, but it may slow the rate of further lung function decline. Pirfenidone is currently only approved to treat idiopathic pulmonary fibrosis and not other forms of pulmonary fibrosis. If the patient's lung function is within clinical standards (50-80% of estimated forced vital capacity), pirfenidone therapy can be initiated.

According to current clinical guidelines, pirfenidone is only effective as long as it is taken and needs to be taken continuously. There is no clear recommendation to interrupt the drug during treatment. If a patient responds well during treatment, the doctor may recommend continued use long-term. Doctors usually recommend that patients stop pirfenidone if they experience severe side effects or if their lung function continues to decline by 10% or more over a year despite taking the prescribed medication. Therefore, whether pirfenidone can be taken for 3 months and stopped for one month, it is best to follow the doctor's advice and use it continuously according to the prescribed dosage and time. Do not adjust the medication dosage yourself.

The original drug pirfenidone has been approved for marketing in China and has entered the scope of Class B medical insurance. Reimbursement is limited to patients who meet the indications. SpecificationsThe price of each box of 100mg*54 tablets is about 500 yuan. There are also generic pirfenidone drugs produced in other countries overseas.

The ingredients of the generic drugs are basically the same as those of the original drug. For more drug information and specific prices, please consult Yaode Medical Consultant.
