Aspirin for Pain, Fever, and Inflammation

Topic Overview

Aspirin (such as ASA or Entrophen) relieves pain and reduces fever and inflammation.

Warning: Do not give aspirin to anyone younger than 18 unless your doctor tells you to do so because of the risk of Reye syndrome.

Be sure to follow the non-prescription medicine precautions.

Aspirin is a non-steroidal anti-inflammatory drug (NSAID). For information about other NSAIDs, see non-steroidal anti-inflammatory drugs (NSAIDs).

Side effects of aspirin include:

  • Ringing in the ears. Stop taking aspirin or take a smaller dose until the ringing goes away.
  • Eye problems, such as blurred or double vision.
  • Dizziness.
  • Rapid, deep breathing.

Stop taking aspirin and call a health professional if side effects do not go away within 4 hours after the last dose of aspirin was taken.
