I switched from OFEV to Esbriet, I learned to mitigate the nausea by taking the pill mid-meal. I slowly tested exposure to the sun to see if I would have a reaction and do not. I bought SPF rated shirts to wear and have made adjustments to wear hats on sunny days, but still no side effect. I have oxygen level average at 88% and will supplement with oxygen when exerting. I will remain active but have to have a day of rest following. Hour long conversations will tire me. I do have to snack between meals, paying attention to diet asI am diabetic. I have been stable for 10 months on Esbriet.
