I just think if a pill is causing your hair to fall out stop using it. I agree NSAIDS are an option since you were taking them for pain (Ibuprofen, naproxen). I've also found that taking omega3 can drastically reduce the pain you get during your monthly. I def have had extremely painful periods too and a change of lifestyle, eating habits along with supplements and I'm pretty much pain free during that time. You will want one that has at least 800mg of (EPA + DHA). I'm very anti-pharmaceutical anything so I think your best bet is to try using something natural. Because I just couldnt take it if my hair was falling out because of the pill.
