Photographic fixatives are chemicals used to develop photographs.
This article discusses poisoning from swallowing such chemicals.
This is for information only and not for use in the treatment or management of an actual poison exposure. If you have an exposure, you should call your local emergency number (such as 911) or the National Poison Control Center at 1-800-222-1222.
- Sodium thiosulfate
- Sodium sulfite/bisulfite
- Boric acid
Photographic fixative can also break down (decompose) to form sulfur dioxide gas.
These chemicals are found in products used to develop photographs.
Before Calling Emergency
Determine the following information:
- The person's age, weight, and condition
- Name of product (as well as the ingredients and strength, if known)
- The time it was swallowed
- The amount swallowed
The National Poison Control Center (1-800-222-1222) can be called 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
The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Blood and urine tests will be done. The person may receive:
- Activated charcoal so that the poison that remains does not absorb into the stomach and digestive tract
- Airway and breathing support, including oxygen. In extreme cases, a tube may be passed through the mouth into the lungs to prevent aspiration.
- Chest x-ray
- EKG (electrocardiogram, or heart tracing)
- Endoscopy -- camera down the throat to see burns in the esophagus and stomach
- Fluids through a vein (by IV)
- Laxatives to move the poison quickly through the body
- Medications to treat symptoms
- Tube through the mouth into the stomach to wash out the stomach (gastric lavage)
How well a person does depends on how much of the poison was swallowed and how quickly the person received medical help. Swallowing these products can cause severe effects in many parts of the body. The faster treatment is received, the greater the chance of recovery.
