Aspirin overdose

Acetylsalicylic acid overdose

Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve mild to moderate aches and pains, swelling, and fever.

Aspirin overdose occurs when someone accidentally or intentionally takes more than the normal or recommended amount of this medicine. This can happen in two ways:

  • If a person accidentally or intentionally takes a very large dose of aspirin at one time, it is called an acute overdose.
  • If a normal daily dose of aspirin builds up in the body over time and causes symptoms, it is called a chronic overdose. This may happen if your kidneys do not work correctly or when you are dehydrated. Chronic overdoses are usually seen in older people during hot weather.

If you or someone you are with overdoses, call your local emergency number (such as 911), or your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.
