What does the abbreviation OTC refer to regarding medications?

The abbreviation OTC stands for "Over the Counter," which refers to medications that can be purchased without a prescription. These medications are typically considered safe and effective for self-treatment of common conditions or symptoms, such as pain relief, cold, or allergy symptoms.

Over-the-counter medications are available to consumers and are regulated by governmental authorities, but do not require the oversight of a healthcare professional for dispensing. This allows individuals to access these medications directly, making them a convenient option for managing minor health issues.

The other options do not accurately reflect established terminology within the medical or pharmaceutical fields. "Order to confer" and "Outside treatment care" do not represent any recognized medical terms associated with medications, while "Overtime care" also lacks relevance in this context. Thus, "Over the counter" stands out as the correct and widely understood term relating to medications that do not require a prescription.
