Patient was educated on Tylenol and its mechanism of action as follows:

1. Tylenol is an OTC pain medication that is used for mild to moderate pain relief, such as, toothaches and muscle pains due to flu.
2. Tylenol also helps with reducing the fever.
3. The mechanism of action of Tylenol is unclear and so, Tylenol is a pain medication that does not belong to either NSAID or opioid pain medication groups.
4. Inhibition of cyclooxygenase enzyme, COX-2, is considered to be the main mechanism of action of Tylenol, which could reduce prostaglandin synthesis, thus contributing to reducing pain and swelling of the tissues.
5. Tylenol often is combined with opioid pain medications, such as, Hydrocodone and Codeine, as reduces the fever and potentiates the action of opioid pain medications.
