keep SUBSTANCES WHICH IF INCLUDED IN MEDICINAL PRODUCTS MAKE THOSE PRODUCTS PRESCRIPTION ONLY MEDICINES AND EXEMPTIONS FROM RESTRICTIONS ON THE SALE AND SUPPLY OF PRESCRIPTION ONLY MEDICINES
The Prescription Only Medicines (Human Use) Order 1997 classifies medicinal products as prescription-only medicines (POM) based on criteria including maximum strength, route of administration, use, pharmaceutical form, maximum dose, maximum daily dose, maximum quantity, and period/frequency of use. It lists specific substances in Schedules 1 and 2 with their applicable conditions, and provides exemptions for certain highly diluted (6x or 6c) homeopathic preparations. It operates in conjunction with the Human Medicines Regulations 2012.
Without prescription-only controls on certain medicinal substances, Britons would face significantly greater risk of harm from medications requiring professional medical assessment before use — a harm that cannot be easily remediated once suffered. While this regulation restricts market supply of certain products, it serves a genuine safety function by ensuring potentially dangerous substances (including various alkaloids, controlled pharmaceuticals, and specific preparations) are only supplied under professional supervision. The costs of regulatory compliance are asymmetrically borne by suppliers, whereas the benefit of safety assurance accrues to the general public who cannot easily assess medication risks. Alternative mechanisms such as product liability or information disclosure would be inadequate substitutes for substances where incorrect self-medication could cause irreversible harm. The exemptions for highly diluted homeopathic preparations (6x, 6c) suggest pragmatic flexibility rather than blanket restriction.
