To be exact, Percocet pills do not contain any Tylenol, they contain acetaminophen. You may wonder about the difference... Well, Tylenol is a brand name for the substance internationally known as acetaminophen. Acetaminophen can be distributed under other brand names, too. And various preparations of Tylenol may contain other ingredients combined with acetaminophen (e.g., codeine). Brand names are subject to copyright. They are products licensed to certain manufacturers. Different manufacturers can produce the same medicines under different brand names. Drugs can also be distributed under their generic names (internationally known names of their active ingredients). Actually, each brand contains some active ingredients known under generic names, but no brand contains other brands.
Both Percocet and Tylenol are brand names. Both Percocet and Tylenol contain acetaminophen. Some preparations of Tylenol contain pure acetaminophen, some may contain other active ingredients together with acetaminophen.
Percocet is a compound medication that consists of oxycodone and acetaminophen. It would be a big mistake to associate Tylenol and acetaminophen in a direct manner, which could lead to a conclusion that Percocet may contain other substances in addition to oxycodone and acetaminophen (e.g., codeine).
And now, a little example. What is Percocet 7.5/500? The figures tell the strengths of active ingredients found in the formulation. In this case, they are 7.5 mg of oxycodone hydrochloride and 500 mg of acetaminophen. Apart from brand-named Percocet, this combination is found in generic variations of the medication produced by several well-known pharmaceutical companies, such as Watson (WATSON 824 pills) and Mallinckrodt (M582 pills).
