Hi Miranda, I started taking tecfidera the day before yesterday. I was warned/advised to take with food – something more than just a snack. After the very first capsule I didn’t expect any side effects but a few hours after I took it my face felt incredibly hot and almost tingly. Not unbearable at all but just bizarre. I dismissed at the time because I was in a very warm room and I have never tolerated heat very well. A few hours after the first dose of yesterday I got the same sensation but slightly worse and my I could feel it in my scalp too. It’s all bearable though. I’ve not had any stomach problems but I’m only three days in and on the starter dose atm. Good luck to you, I’m sure it’ll be fine.
