All I really know about Merck is that it is a big company and makes drugs and vaccines. I am familiar with the products we use here, such as Proscar, Zocor, Cosopt eye drops, Fosamax, Cozaar err I'm running out of products I know.
I do recall good drug information for product releases such as Fosamax. I can recall talking to a rep from Merck when Fosamax first came out, and talking about the hip advantages it give.
