 Question, what will you find on all over-the-counter or OTC medicine packages to help you choose the right drug and use it safely? The answer, the Drug Facts Label. This label lists the medicine's active ingredients and purpose, how much to take, and warnings you should know before using it. Remember, even OTC medicines you buy without a prescription can cause side effects you don't want. So follow the information listed on the Drug Facts Label.
