According to the sources provided, there may be some risks associated with taking Tylenol (acetaminophen) with Lipitor (atorvastatin). The first source, Drug Patent Watch [1], provides information about Tylenol, including its active ingredient, dosage forms, and patents. The second source, Drugs.com [2], provides a drug interaction checker that indicates that there may be a moderate interaction between Tylenol and Lipitor. This interaction can increase the risk of liver damage, especially in people who already have liver problems. The third source, Mayo Clinic [3], provides general information about Lipitor, including warnings and precautions. It notes that people who have liver disease or a history of liver problems should use Lipitor with caution, and that Tylenol can also cause liver damage if taken in large doses or for a long time.

Based on this information, it is important to be cautious when taking Tylenol and Lipitor together, especially if you have liver problems or a history of liver disease. You should talk to your doctor or pharmacist before taking these medications together, and follow their instructions carefully. If you experience any symptoms of liver problems, such as yellowing of the skin or eyes, dark urine, or abdominal pain, you should seek medical attention immediately.
