Piroxicam overdose
Feldene overdose
Piroxicam is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve mild to moderate aches and pains and swelling. Piroxicam overdose occurs when someone accidentally or intentionally takes too much of this drug. People with kidney or liver disease are more likely to develop serious side effects or worsening of their disease from NSAIDs.
As a group, and because of their common use, NSAIDs are responsible for more serious drug-related side effects than any other class of pain relieving drugs.

Poison Control
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 hotline 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.
Take the container with you to the hospital, if possible.
What to Expect at the Emergency Room
The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure.
Symptoms will be treated as appropriate. The person may receive:
- Activated charcoal
- Airway support, including oxygen, breathing tube through the mouth (intubation), and ventilator (breathing machine)
- Blood and urine tests
- Chest x-ray
- ECG (electrocardiogram, or heart tracing)
- Fluids through the vein (intravenous or IV)
- Laxative
- Medicines to treat symptoms
In rare, serious cases, more treatments may be needed, including kidney dialysis (machine). Most people will be discharged from the emergency department after being observed for a period of time.
Outlook (Prognosis)
Recovery is likely. In rare cases, kidney damage may be permanent and require long-term dialysis.
