Esbriet

Common use

Esbriet (pirfenidone) may be used to treat adults with idiopathic pulmonary fibrosis (IPF), a lung condition that causes inflammation and scarring in the lungs. Esbriet’s mechanism of action involves slowing down the build-up of scar tissue in the lungs. Esbriet is not a cure for IPF, but it does slow how quickly the condition progresses.

Dosage and direction

Take Esbriet exactly as your doctor tells you to take it. Your doctor may change your dose of Esbriet as needed. Esbriet is usually taken three times a day. Take Esbriet with food at the same times each day. This may help to decrease side effects such as nausea and dizziness. Esbriet is usually taken long-term.
