- Tylenol can damage the liver. Therefore, if you already have liver problems, you should talk to your healthcare provider before taking Tylenol.
- If you drink three or more alcoholic beverages per day, your body may not handle Tylenol as well as it should. This means that you may develop Tylenol toxicity at lower dosages than normal.

- Tylenol can interact with other medications (see Tylenol Drug Interactions for more information).

- Some people who are allergic to salicylates (such as aspirin) may also be allergic to Tylenol. However, many people with such allergies can take this drug without any problems.
- Tylenol is considered a pregnancy Category B medication. This means that it is probably safe for use during pregnancy (see Tylenol and Pregnancy).
