Tylenol contains the active ingredient acetaminophen, a common and mostly safe painkiller. Though side effects are very rare, certain factors such as heavy alcohol use or chronic overdose may lead to side effects that can be potentially life-threatening.
Allergic Reactions
Some people experience allergic reactions to acetaminophen, including swelling of the mouth and throat, difficulty breathing and a choking sensation.
Nausea
Tylenol may induce nausea in some individuals or in cases of overdose. Some sensitive individuals need to take the lowest possible dose and not exceed dosage in the time allotted to avoid this side effect.
Unusual Bruising
Acetaminophen often makes some individuals bleed or become bruised more easily than normal. This can be a potentially serious side effect, and individuals who experience this should talk to a doctor.
Abdominal Bleeding and Pain
Extensive use of Tylenol, particularly with other drugs, may result in abdominal pain and bleeding. Acetaminophen is an acidic drug that may damage the lining of the stomach in large doses.
Liver Damage or Failure
Heavy doses may result in liver damage, failure or even death. This often occurs when Tylenol is taken in conjunction with alcohol or certain other drugs. Chronic use may also result in liver damage and failure.
