What Is Tylenol?

Tylenol is the brand name for acetaminophen, a medication classified as a miscellaneous analgesic. Its primary functions include:drugs

• Pain relief for mild to moderate aches (headaches, muscle pain, arthritis, menstrual cramps).drugs

• Fever reduction, often in viral illnesses such as colds and influenza.mayoclinic+1
