Clinitest tablets poisoning
Clinitest tablets are used to test how much sugar (glucose) there is in a person's urine. Poisoning occurs from swallowing these tablets.
Clinitest tablets used to be used to check how well a person's diabetes was being controlled. These tablets are rarely used today. They are not meant to be swallowed, but could be taken by accident, since they look like pills.

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
The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure.
Tests that may be done include:
- Bronchoscopy: camera placed down the throat to see burns in the airways and lungs.
- Chest x-ray to see if there is air leakage into the tissue around the heart and lungs.
- Endoscopy: camera placed down the throat to see burns in the esophagus and stomach.
Treatment may include:
- Additional flushing of the eyes.
- Medicine to treat symptoms and correct the body's electrolyte (body chemical) and acid-base balance.
- Fluids through a vein (IV).
- Breathing support, including tube through the mouth into the lungs and ventilator (breathing machine).
How well someone does depends on the amount of poison swallowed and how quickly treatment is received. The faster medical help is given, the better the chance for recovery.
Extensive damage to the mouth, throat, eyes, lungs, esophagus, nose, and stomach are possible. The ultimate outcome depends on the extent of this damage. Damage continues to occur to the esophagus and stomach for several weeks after the poison was swallowed. Death is possible.
Keep all medicines in child-proof containers and out of the reach of children.
