Castor oil overdose

Alphamul overdose; Emulsoil overdose; Laxopol overdose; Unisol overdose

 

Castor oil is a yellowish liquid often used as a lubricant and in laxatives. This article discusses poisoning from swallowing a large amount (overdose) of castor oil.

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 exposure, 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.

Ricinus communis (castor oil plant) contain the toxin ricin. Seeds or beans swallowed whole with the hard outer shell intact typically prevent absorption of significant toxin. Purified ricin derived from the castor bean is highly toxic and lethal in small doses.

Before Calling Emergency

 

Have this information ready:

  • Name of product (as well as the ingredients and strength, if known)
  • Time it was swallowed
  • Amount swallowed

 

Poison Control

 

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. 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 with you to the hospital, if possible.

The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. The person may receive:

  • Blood and urine tests
  • ECG (electrocardiogram or heart tracing)
  • Intravenous fluids (through a vein)
  • Medicine to treat symptoms

 

Outlook (Prognosis)

 

Normally, castor oil should cause few problems. Recovery is very likely.

If nausea, vomiting, and diarrhea are not controlled, serious dehydration and electrolyte (body chemical and mineral) imbalances may occur. These can cause heart rhythm disturbances.

Keep all chemicals, cleaners, and industrial products in their original containers and marked as poison, and out of the reach of children. This will reduce the risk of poisoning and overdose.
