Hi, I started Siponimod back in June. Its been ok, cant say if it works or not but the side effects havent been too bad. My blood pressure went down quite low to begin with but that has settled, my liver function went up but again that is coming down again - and I didnt feel any different, just knew because of the blood tests. The worse thing has been recently having diarreah, but i take loperamide if needed.
