Acetaminophen toxicity can happen as a result of an acute overdose or prolonged usage. Acute overdose are the consumption of a lethal amount of a drug within an 8 hour period, while a chronic overdose results from a repeated intake of doses or above the safe limit. The recommended dose of acetaminophen in adults is 650 to 1,000 mg every 4 to 6 hours, not exceeding 4, 000 mg/day. Acetylcysteine (Mucomyst) must be readily available in case of toxicity.
