In reply to drunken monkey:
Thanks for all the replies folks - Appreciate it. I've been trying to get back into Ultra running this year, and it's only recently that I've noticed these warnings about Brufen.
I wouldn't say I'm popping them like sweets, but I have on occasion, used them on runs in excess of 30 miles, just to help.
One of the race briefings I've seen for a race coming up, actually mentions that the race directors [May] disqualify anyone seen taking ibuprofen before or during the race.
it just made me wonder what the specific risk with this drug is, as its so widely taken.
thanks again for all the replies
