Tylenol is a brand of medication, advertised for reducing pain, reducing fever, and relieving the symptoms of allergies, cold, cough, headache, and influenza. An active ingredient in these medications is acetaminophen (paracetamol), an analgesic and antipyretic, although other ingredients with significant effects are included in some variants. Like the generic names paracetamol and acetaminophen, the brand name Tylenol is derived from a chemical name for the compound, N-acetyl-para-aminophenol.
