I read that it was when googling it online, as I'm trying to find an OTC with some for migraines. I had some tablets with this active ingredient that seemed to work that I am just about out of (got them when visiting extended family in the Czech Republic), and I haven't been able to find it in the States. I know it's a common OTC pain med (also had some from Australia a couple years back). My issue is that most common U.S. OTCs and pharmaceuticals don't work for me, esp. with the bad migraines I've had lately. Thanks to anyone who can offer some helpful information (or tell me if I can buy Panadol, etc. somewhere in the U.S.). C.
