Explanation

Tylenol, also known as acetaminophen, is a common medication used to relieve pain and reduce fever. While it is generally safe when taken as directed, it can cause side effects. Most people experience mild side effects, such as nausea or a rash.

However, it's important to be careful about the amount you take. Taking too much Tylenol can lead to serious liver damage, which is a more severe side effect.

Key Points:

  1. Mild Side Effects: These can include stomach upset, nausea, or skin rash. These are not very common and usually not serious.
  2. Serious Side Effects: Taking too much acetaminophen can cause liver damage, which is very serious. It is important to follow the dosage instructions on the package or given by a doctor.

If you have any concerns about taking Tylenol or experience any unusual symptoms, it is important to talk to a healthcare professional.
