Every over-the-counter (OTC) medicine has one or more specific ingredients called active ingredients that make the medicine work. For example, the active ingredient is what helps your fever go down, reduces your pain, or relieves your cough. It is especially important to pay attention to the active ingredients in your OTCs if you are taking more than one medicine—whether OTC or prescription—to make sure you are not taking too much of the same active ingredient. Too much of an active ingredient can be harmful.
