What type of medications are considered "over the counter"?

Over-the-counter medications are defined as those that can be purchased without a prescription. This means they are deemed safe and effective for public use without the need for a healthcare provider's supervision or a written order. This classification allows consumers to manage certain health conditions independently, such as pain relief, allergies, or colds, by obtaining these medications from pharmacies, grocery stores, or other retail outlets.

Prescription-strength medications require authorization from a healthcare provider and are typically used for more severe conditions or might involve a greater risk if misused. Controlled substances refer to drugs that are regulated due to their potential for abuse and dependency, thus requiring strict oversight and a prescription. Experimental drugs are those still undergoing clinical trials and have not yet been approved for general use, meaning they cannot be obtained over the counter as they may not meet the safety and efficacy standards established by regulatory bodies.
