Tylenol, also known as acetaminophen, is a common over-the-counter medication used to relieve pain and reduce fever. While Tylenol is generally considered safe when used as directed, it can cause side effects in some cases. Here are some potential side effects of Tylenol:

1. Liver damage: One of the most serious side effects of Tylenol is liver damage. This can occur if you take too much Tylenol or take it for an extended period of time. It is important to follow the dosage instructions carefully and talk to your doctor if you are taking Tylenol for more than a few days.
2. Stomach pain: Tylenol can cause stomach pain, nausea, and vomiting in some people. This is more common when taking higher doses of Tylenol.
3. Allergic reactions: Some people may have an allergic reaction to Tylenol. Symptoms of an allergic reaction can include hives, rash, itching, and difficulty breathing.
4. Rash: In rare cases, Tylenol can cause a skin rash. If you develop a rash while taking Tylenol, stop taking it and talk to your doctor.
5. Blood disorders: Tylenol has been linked to rare cases of blood disorders, such as thrombocytopenia (low platelet count) and leukopenia (low white blood cell count).

It is important to note that Tylenol is generally considered safe when used as directed. However, if you experience any of these side effects or have concerns about taking Tylenol, talk to your doctor.
