Ketoprofen is a nonsteroidal anti-inflammatory drug. It is used to treat pain, swelling, and inflammation. Ketoprofen overdose occurs when someone takes more than the normal or recommended amount of this medicine. This can be by accident or on purpose.
This article is for information only. DO NOT use it to treat or manage an actual overdose. If you or someone you are with has an overdose, 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.

Your local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.
This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.
What to Expect at the Emergency Room
Take the container to the hospital with you, if possible.
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure.
Tests that may done include:
- Blood and urine tests
- ECG (electrocardiogram, or heart tracing)
- Chest x-ray
- Endoscopy -- camera placed down the throat to check for burns in the esophagus and stomach
Treatment may include:
- Fluids through a vein (by IV)
- Medicine to treat stomach inflammation and bleeding, breathing problems, and other symptoms
- Activated charcoal
- Tube through the mouth into the stomach to empty the stomach (gastric lavage)
- Breathing support, including a tube through the mouth into the lungs and connected to a breathing machine (ventilator)
How well someone does depends on the amount of ketoprofen that was swallowed and how quickly treatment is received. The faster medical help is given, the better the chance for recovery.
A mild overdose of ketoprofen does not usually cause serious problems. The person may have some stomach pain and vomiting (possibly with blood).
However, a large amount of internal bleeding is possible, and a blood transfusion may be needed. Passing a tube with a camera through the mouth into the stomach may be needed to stop the internal bleeding.
A large overdose can cause serious damage to children and adults. Death may occur.
