Tylenol (acetaminophen) is an analgesic (pain relievers) and antipyretics (fever reducers) used for treating pain and fever associated with many conditions. Generic formulations of Tylenol are available. Tylenol may cause nausea, rash, and headache.
The oral dose of Tylenol for adults is 325 to 650 mg every 4 to 6 hours. The maximum daily dose is 4 grams. Questran (cholestyramine) reduces the effect of acetaminophen by decreasing its absorption into the body from the intestine. Tylenol is used in all stages of pregnancy and is the drug of choice for short-term treatment of fever and minor pain during pregnancy. Although Tylenol is excreted in breast milk in small quantities, it is safe to be used by nursing mothers.
Our Tylenol Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
