I was unable to tolerate Esbriet. Initially I started with 1 capsule 3 times per day, gradually going up to 3 capsules 3 times a day. Every day, and I do mean every day, I was extremely fatigued with dizziness and nausea. I stopped taking Esbriet and the symptoms stopped. After a year my doctor advised that I start again with Esbriet, this time only taking 1 capsule 3 times/day. Unfortunately the same symptoms started again on a daily basis, so I stopped. Fortunately my IPF has not gotten any worse, but who knows when it can flare up again. Just for information, I never did use OFEV because I have 3 heart stents.
