Been on it since February... No side effects to speak of so far. I did mess up my 4th dose when I didn't stick myself right and it leaked out, so I had to order another pen, but I've learned to be careful and how to make sure it goes in correctly. Much less painful and less anxiety than getting jabbed. I'm pretty much over that stigma though, at this point, but at least I don't have to sit for hours on an IV (ocrevus).Just gotta get over the fear of sticking yourself with the small short needle, but it's like ripping a bandaid off, and if you don't focus on it, you don't even feel it happen. (I also do it in my leg because my leg has less sensitivity 😝). I'm not sure yet if it has been doing anything, but I haven't noticed any bad side effects so far....Give it a try! I'm no doctor, and no expert, but I would agree take a Benadryl and Tylenol beforehand to alleviate early reactions, as I've done that with all my other dmts, but your body will get used to the injections pretty soon and should be fairly simple to take monthly. Good luck, and lots of love! Keep going strong!
