And it is becoming a bigger problem than originally thought.

Since 2010, poison control centers in the U.S. have seen an almost 400 percent increase in calls of kids 12 and under ingesting hand sanitizer, the Georgia Poison Center recently released.

In 2010, the center had 3,266 cases of kids ingesting hand sanitizer. In 2014, it increased to 16,117.

The amount of alcohol in hand sanitizer is between 45 percent and 95 percent, and even small amounts can cause alcohol poisoning, CNN reported.

Dr. Gaylord Lopez, director of the Georgia Poison Center, said parents and teachers should keep the bottles out of reach of kids and monitor the use. Lopez also suggested using non-alcohol-based products or wipes.
