Medicines a person can buy without a prescription are called nonprescription or over-the-counter (OTC) medicines. They may be taken to treat minor health problems at home.
Examples of over-the-counter medicines are acetaminophen, aspirin, antacids, decongestants, antihistamines, and laxatives.
It?s important to talk to the doctor about what medicines may not be safe to give children.
