Unlicensed medicine in plain English

A medicine without a marketing authorisation from the MHRA for the use in question.

Unlicensed does not mean unregulated or illegal. It means the product has not been through the licensing process that assesses quality, safety and efficacy for a specific indication, so the prescriber takes on greater responsibility for the decision.

It also means the product may not lawfully be advertised. That is why no UK clinic website, including this one, publishes product names, images or prices.
