What is the difference between OTC and prescription medicine?
OTC medicines are judged safe enough for people to choose and use themselves by following the label, so anyone can buy them. Prescription medicines need a clinician's authorisation because dosing, interactions or risks require professional judgement. Some drugs sit in a middle category sold only by a pharmacist.
What does OTC mean in stocks?
It means the security is traded off-exchange, dealer to dealer, rather than on a listed market like the NYSE. OTC stocks include many small or foreign companies, and they typically face lighter disclosure requirements and lower liquidity.
Are OTC medicines safe?
They are safe when used as directed, but they are still drugs. Overdosing, doubling up on products containing the same active ingredient, or mixing them with prescription medicines can cause real harm.
