The maximum allowable daily dose of Tylenol
) is 4 grams (or 4000 mg) in adults and 90 mg/kg in children.
When taken according to directions, side effects from acetaminophen are rare. The most serious side effect is liver damage
. Kidney toxicity is also a possibility. The risk of liver damage increases with:
Large doses of acetaminophen
Chronic use of acetaminophen
Concomitant use of acetaminophen with alcohol (i.e. taken together) or with other drugs that can also potentially cause liver damage
It is said that a single dose of more than 4 grams can be dangerous but since you have taken only 2 grams of acetaminophen,the chances of liver toxicity are very less however it can not be completely ruled out.
Go to ER if you develop nausea
as that could be the first phase of liver toxicity and you should be under observation for that.
