Hello @LisaJane672. I've been on Tec for 4 years with no problems. Almost everyone that starts it seems to get the 'flush' effect which is temporary. Some people get some gastric side effects; I fortunately didn't. The most important thing is to take it with food, a mix of fat and protein, to mitigate any gastric issues. As a example, my daily breakfast is fruit, Greek Yogurt and lots of nuts. Lots swear by peanut butter as a great source. It's best to space out taking them. You need to get into the habit of always keeping a spare at work/in your car/ handbag in case you forget when you eat outside of home. If you do a search in the search box there are plenty of posts. All the best!

I have been on Tecfidera for about 7 months. Had a lot of flashing/burning from beginning, but now just there and now. Like Vixen said take it with food,that helps and I'm trying to take them always in the same time.
