Acetaminophen is the same as Tylenol. Tylenol is a brand name for the generic medication, according to Drugs.com. The medication is used to reduce fever and to alleviate pain from headaches, backaches, toothaches, colds and flu, arthritis, menstrual cramps and muscle soreness, notes WebMD.
Because acetaminophen comes in many brands, forms and dosages, it is important to read and adhere to the dosing information, states WebMD. Overdoses sometimes cause liver damage or death, warns Drugs.com. Nausea, vomiting, appetite loss, abdominal pain, perspiration, confusion and weakness are initial signs of acetaminophen overdose. Later symptoms include dark-colored urine and yellowing of the skin and the whites of the eyes.
