Is Watson 749 stronger then Watson 512?

I think 500 mg is the 512

749 750 mg

Wrong, wrong and wrong!

First, there is no pill indexed "Watson 512", as Watson Pharmaceuticals does not manufacture "512" pills. The pill you seem to mean must be Mallinckrodt's product (no WATSON letters on it, just number 512). But it is not 500mg.

Second, there IS a pill indexed "Watson 749", and it is a Watson product. But it is not 750mg in strength.

Both "512" pill and "Watson 749" are generic versions of brand name Percocet, equal in strength containing 350mg of oxycodone hydrochloride and 5mg acetaminophen each.
