I am looking for a good web-site that discusses drug inter-actions & compatibility, both prescription & over-the counter. Anyone know of any good ones?

try this one (P.S. it's a little slow)

Thanks Sid. This is an excellent web-site.

Not worried about the speed. The quality content more than makes up for it.

Sid, that is a very nice site. I found that some of my meds can interact with the other.
