Tylenol 4 is a compound analgetic that consists of 60mg codeine phosphate and 300mg acetaminophen (paracetamol). It is also often called Tylenol 4 with codeine. The amount of codeine is doubled each time we go from Tylenol #1 to Tylenol #4. In Tylenol 1, it is only 8mg, then 15mg in Tylenol 2, 30mg in Tylenol 3, and finally, 60mg in Tylenol 4. The amount of acetaminophen is 300mg in each preparation. In the USA, Tylenol products contain no caffeine. But Tylenol #2 and #3 manufactured in Canada contain 15mg caffeine each, too. However, Tylenol 4 is just a mixture of 60mg codeine and 300mg acetaminophen (together with some inactive components, of course).
