It’s a .com which means it’s a commercial site not an academic or organizational site but looking it over it seems like it’s a pretty reliable site. They do post where they get their info from and they do tell you how to cite it if you are using it for a reference so I think it’s pretty legit.

You might also check pdr.net which is the standard physician’s reference for drug descriptions. The name comes from Physician’s Desk Reference which was a hard copy reference book.

Ok. I asked about another site a few months ago, about medical info but it turned out it is a joke site.
