Over-the-counter eye drops or nasal decongestant sprays can pose a serious health threat to children who swallow them and should be kept out of the reach of kids at all times, the U.S. Food and Drug Administration warns.

These products — sold under brand names such as Visine, Dristan and Mucinex, as well as generic and store brands — contain active ingredients called imidazoline derivatives.

Between 1985 and 2012, there were 96 reported cases in which children aged 1 month to 5 years accidentally swallowed products containing imidazoline derivatives in the United States. Although there were no reported deaths, 53 of the children had to be hospitalized due to symptoms such as nausea, vomiting, sleepiness, fast heart beat and coma, according to the FDA.
