Quick take on ingesting Saccharin

Toxicity? Depends on the amount swallowed

Most common symptoms if swallowed? Upset stomach

When to seek immediate help and call 911? Choking or difficulty breathing.

Has your child eaten Saccharin packets?

Saccharin is an artificial sweetener that is 200 to 700 times sweeter than table sugar, but contains no calories. It is often used as a sugar substitute in diet beverages, candy and jams. If your child has eaten several packets of Saccharin, they are probably still under the acceptable daily intake (ADI). The ADI is 15 milligrams of saccharin per 1 kilogram of body weight. To put this into context, a 35-pound child would have to eat 6-7 packets of Sweet and Low before reaching the ADI. Saccharin is not toxic, but the small packets can be a choking hazard if swallowed.

Four common methods of poison exposure

In mouth or eaten? Give water and small snacks to help reduce taste and upset stomach. If choking or difficulty breathing, seek immediate help and call 911.

On skin? If skin irritation occurs, wash affected area with soap and water. If it does not subside, call the Poison Control Center at 1-800-222-1222.

In eyes? Flush eyes with water for at least 15 minutes. If eye irritation persists, call the poison control center at 1-800-222-1222.

Inhaled? Remove the child from exposure and get fresh air. If irritation persists, call the Poison Control Center at 1-800-222-1222.
