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).
