Is ibuprofen also Tylenol

It's neither - Aspirin is acetylsalicylic acid and Tylenol(brand name) is acetaminophen -

ibuprofen and aspirin belong to the same drug class - Non-steroidal anti-inflammatories (NSAIDS), while acetaminophen is an analgesic (pain reliever) -

they can have similar effects on the body using differing mechanisms.
