Taking these together with Tylenol can expose you totoxic levels of acetaminophen.
For healthy adults, more than 4,000 milligrams of acetaminophen per day increases the risk of hepatotoxicity.
For children and people with liver disease, hepatotoxicity can occur at far lower doses.
Always read product labels carefully to ensure that you are not doubling doses.
Instead, the chemicals start to accumulate and damage the liver.
Drinking alcohol with acetaminophen only increases the risk of hepatotoxicity, even at lower doses.
For this reason, alcohol should never be consumed while you are taking Tylenol.
Moreover, if you consume three or more alcoholic drinks per day, you shouldneveruse Tylenol.
Signs and symptoms of acetaminophen-induced hepatotoxicity include:
Symptoms often develop 12 hours or more after a significant overdose.
