When a child's sniffles and sneezes won't go away for weeks, the cause might be allergies. The FDA regulates prescription and OTC medicines that offer allergy relief, plus allergen extracts to diagnose and treat allergies. Read and follow the directions when giving any medicine to children.

The best way to dispose of your expired, unwanted, or unused medicines is through a drug take back program. Or you can do it at home. Check the FDA flush list.
