Over-the-counter (OTC) medicines are drugs you can buy without a prescription. Some OTC medicines relieve aches, pains, and itches. Some prevent or cure diseases, like tooth decay and athlete's foot. Others help manage recurring problems, like migraines and allergies.

In the United States, the Food and Drug Administration decides whether a medicine is safe and effective enough to sell over-the-counter. This allows you to take a more active role in your health care. But you also need to be careful to avoid mistakes. Make sure to follow the instructions on the drug label. If you don't understand the instructions, ask your pharmacist or health care provider.

Also keep in mind that that there are still risks to taking OTC medicines:

If you have been taking an OTC medicine but your symptoms don't go away, contact your health care provider. You should not take OTC medicines longer or in higher doses than the label recommends.
