Final answer:
Over-the-counter drugs can include pain relievers, cold and allergy medicines, and cough medications. They are available without a prescription and must provide directions for use and information about side effects.
Step-by-step explanation:
Over-the-counter drugs (OTC) can include a wide variety of medications such as pain relievers, cold and allergy medicines, and cough medications. These drugs are available without a prescription and can be purchased directly from a pharmacy or store.
By law, OTC drugs must provide adequate directions for use and information about possible side effects. For example, acetaminophen (Tylenol) and nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin and ibuprofen are common examples of OTC pain relievers.
