Diclofenac sodium overdose

Voltaren overdose

Diclofenac sodium is a prescription medicine used to relieve pain and swelling. It is a nonsteroidal anti-inflammatory drug (NSAID). Diclofenac sodium 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.

Poisonous Ingredient

Diclofenac sodium can be harmful in large amounts.

Where Found

  • Voltaren
  • Arthrotec
  • Solaraze

Other medicines may also contain diclofenac sodium.

Symptoms

Symptoms of a diclofenac sodium overdose include:

In very rare cases, severe breathing problems, coma, convulsions, and blurred vision may occur.

Home Care

Seek medical help right away. DO NOT make the person throw up unless poison control or a health care provider tells you to.

Before Calling Emergency

Have this information ready:

  • Person's age, weight, and condition
  • Name of the product (ingredients and strength, if known)
  • Time it was swallowed
  • Amount swallowed
  • If the medicine was prescribed for the person

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 national 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.

What to Expect at the Emergency Room

Take the container to the hospital with you, if possible.

The provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure.

Tests that may be done include:

  • Blood and urine tests
  • Chest x-ray
  • ECG (electrocardiogram, or heart tracing)

Treatment may include:

  • Fluids through a vein (by IV)
  • Medicine to treat stomach pain, inflammation and bleeding, or breathing problems
  • Activated charcoal
  • Laxative
  • Tube through the mouth into the stomach if vomiting contains blood
  • Breathing support, including a tube through the mouth and connected to a breathing machine (ventilator)

Outlook (Prognosis)

Taking too much diclofenac sodium does not usually cause serious problems. The person may have some stomach pain and vomiting (possibly with blood). However, these symptoms will likely get better. In rare cases, a blood transfusion is needed. Passing a tube through the mouth into the stomach (endoscopy) may be required to stop internal bleeding.
