@Hi, I’m taking Tecfidera since 2018 and have had heartburn for a few years. Had a recent endoscopy and diagnosed with gastritis and evidence of peptic ulcer. Trying to figure if it’s a result of Tecfidera? on Shift.ms

Good afternoon I have been taking the same drug since 2018 too. I'm in the process of changing drugs but to date I've never had any stomach problems as you describe. In the interim try taking it in a spoonful of peanut butter towards the end of a protein based meal. You could also ask for Omeprazole.
