PIRFENIDONE
About
PIRFENIDONE is an anti-fibrotic medicine used to treat idiopathic pulmonary fibrosis (IPF) in adults. IPF is an irreversible disease that is marked by a progressive decline in lung function. The tissues in the lungs become swollen and scarred over time, due to which it gets difficult to breathe deeply. The scarring makes it hard for the lungs to work properly.
PIRFENIDONE contains ‘Pirfenidone’, which helps in reducing the scarring and swelling in the lungs by decreasing the release/activity of naturally occurring growth factors in the body, thereby helps you breathe better. PIRFENIDONE helps in slowing down the progress of idiopathic pulmonary fibrosis.
In some cases, you may experience certain common side effects such as nausea, tiredness, diarrhoea, indigestion, loss of appetite, headache, and photosensitivity. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Consult your doctor before taking PIRFENIDONE if you are pregnant or breastfeeding. PIRFENIDONE may cause tiredness and dizziness, so drive with caution. Avoid consuming alcohol with PIRFENIDONE as it could lead to increased dizziness. PIRFENIDONE is not recommended for children below 18 years as safety and effectiveness have not been established. Keep your doctor informed about your health condition and medicines to rule out any side effects.

Patients Concern
Disease/Condition Glossary
Idiopathic pulmonary fibrosis (IPF): Idiopathic pulmonary fibrosis belongs to a group of interstitial lung diseases. It is an irreversible chronic disease marked by a progressive decline in lung function. The tissues in the lungs become inflamed and scarred over time, due to which it gets difficult to breathe properly. The scar tissue, known as fibrosis, becomes thick /stiff over time, making it hard for the lungs to work efficiently. This causes decreased lung function, which leads to increased breathlessness and coughing. Breathing difficulties can lead to other medical problems. Symptoms of IPF are shortness of breath, persistent dry cough, loss of appetite, weight loss, rounded and widened tips of the fingers and toes.
