What Does Over-the-Counter (OTC) Mean on a Medicine?
Over-the-counter · say it: OH-ver the KOWN-terAlso written: OTC, non-prescription medicine, over the counter
Short answer
Over-the-counter (OTC) means a medicine you can buy without a prescription, from a pharmacy, shop or supermarket.
What it means
An over-the-counter medicine is one you can buy without a prescription. Regulators allow this when the medicine is considered suitable for people to use on their own for common, short-term problems, following the label.
OTC labels carry a standard 'Drug Facts' panel or leaflet with uses, warnings, when to stop and when to ask a doctor. Those warnings matter because nobody checks your other medicines or conditions for you. Many OTC medicines, such as pain relievers and cold remedies, contain the same active ingredient as other products, which makes doubling up easy.
OTC is the opposite of prescription-only. Some medicines are available both ways, often at a lower strength or smaller pack size over the counter.
