Newly diagnosed, just started on Pentasa today, 4 500 mg caps per day. Took my second dose this evening and after doing some reading on here of some peoples' experiences and having a strong emotional reaction (as I know I'm prone to panic attacks but I don't usually faint), I blacked out on my bed. I woke up dizzy and sweaty, ears ringing, but I'm overall ok. My fiancé was here to help me but he and I are both very worried. Can Pentasa cause fainting or did I just have a bad panic attack? Being newly diagnosed it's been taking an interesting emotional toll so it's entirely possible that this is just a panic attack, as I'm not seeing much about Pentasa and fainting on the Internet. I have a childhood history of breath holding spells and subsequent fainting but I have long since outgrown that. Anyone else black out like that?
