Acetaminophen is the active ingredient found in many pain relievers that are used to treat headaches and back pain and reduce fever. For most consumers, there may be no side effects associated if the recommended dose of the medication is used. The FDA has placed a daily limit on the amount of acetaminophen adults should take as 4,000 milligrams. Taking more than this amount can lead to an acetaminophen overdose and possible liver damage, states CNN.

Acetaminophen is also linked to rare skin diseases that cause symptoms such as skin rashes, blister or pustule formations and skin damage. Stevens-Johns Syndrome and toxic epidermal necrolysis can lead to a hospital stay and even death, states the U.S. Food and Drug Administration. Acute generalized exanthematous pustulosis goes away after discontinuing acetaminophen. The FDA requires warnings on labels for products containing this ingredient.

There are other warnings associated with acetaminophen, such as not to consume alcohol while taking it, and that patients with diabetes or phenylketonuria should speak with their doctors before using it, as noted by WebMD.
