I am on Tecfidera now and although my Dr follows my blood work extremely closely for WBC changes she has never mentioned changes or anticipated changes in my platelets. I would also be interested to hear of anyone has heard of platelet changes while on Tecfidera

You are not the only one to have this. My Dr. does not currently believe its related to Tecfidera but I do. My platelet count has been gradually dropping. My periods are heavier and I have explainable bruising. They don't want to admit that unusual side affects are in fact side affects. We all need to be sure to report unexpected side affects. I'm hoping my body can hold out until Ocrilizamab is on the market...

I've been on tecfidera for over 2 years. WBC seems to remain at a very good level however I am seeing a drop in platelet count. Will be checking with my neurologists next week.
