Features

• Acetaminophen is in a class of pain-relieving, fever-reducing medications called "analgesics" and "antipyretics." Aspirin, on the other hand, is in a class of medications called "non-steroidal anti-inflammatory drugs (N-SAIDs)."
  
  

Applications

• Both Tylenol and aspirin are used to treat pain, inflammation, and fever. They are most commonly used to ease the symptoms associated with headaches, muscle pain, the common cold, menstrual cramps, and mild arthritis pain. Aspirin is often used to prevent or treat strokes and heart attacks.
  
  

Warnings

• Both medications should be taken only as directed. Taking more than the recommended dose can lead to long-term effects such as liver disease. Pregnant or nursing mothers should contact a physician or pharmacist before taking either medication.
  
  

Comparisons

• According to the manufacturer, Tylenol is unlikely to cause stomach irritation like other pain relievers such as aspirin. Acetaminophen is not nearly as effective as aspirin in reducing inflammation.
  
  

Dosing

• A doctor should be consulted to establish how many milligrams of aspirin or acetaminophen is appropriate for specific consumers. It is recommended that aspirin be taken with a glass of water, milk, or some food to lessen the likelihood of experiencing an upset stomach. Acetaminophen can be taken with or without food.
