SIDE EFFECTS: When used appropriately, side effects with acetaminophen are not common. The most serious side effect is liver damage due to large doses, chronic use or concomitant use with alcohol or other drugs that also damage the liver.

Chronic alcohol use may also increase the risk of stomach bleeding.

Other important side effects include:

  • hypersensitivity reactions and
