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.
This article is for information only. Do NOT use it to treat or manage an actual poison exposure. 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.
The poisonous ingredients in Clinitest tablets are:
- Copper sulfate

- Burns and burning pain in the mouth and throat

Before Calling Emergency
Have this information ready:
- Person's age, weight, and condition
- The name of the product
- When it was swallowed
- The amount swallowed
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. 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.
The person may receive:
- Additional flushing of the eyes
- Breathing support, including tube through the mouth into the lungs and ventilator (breathing machine)
- 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.
- Fluids through a vein (IV)
- Medicine to treat symptoms and correct the body's electrolyte (body chemical) and acid-base balance
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.
