POM to P Flashcards
Reclassification from POM- P
MHRA must be satisfied that it would be safe to allow the medicine to
be supplied without a prescription.
• It is a medicine which no longer fulfils any of these criteria:
o it is likely to present a direct or indirect danger to human health,
even when used correctly, if used without medical supervision
o it is frequently and to a very wide extent used incorrectly, and as a
result is likely to present a direct or indirect danger to human health
o it contains substances or preparations of substances of which the
activity requires, or the side effects require, further investigation
o it is normally prescribed by a doctor for parenteral administration
(that is, by injection)
Reclassification:
The criteria for P-to-GSL
MHRA must be satisfied that it:
• ‘can with reasonable safety be sold or supplied otherwise than by or under
the supervision of a pharmacist’ (Medicines Act 1968, section 51).
what does reasonable safety mean?
• ‘Reasonable safety’ may be usefully defined as “Where the hazard to
health and the risk of misuse or the need for special precautions in handling
are small, and where wider sale would be a convenience to the purchaser”
Reclassification P- POM
Less often medicines can be upgraded from P to POM if new risks are
identified
o When a P medicine no longer meets the requirements for supply with
legal status ‘P’ for example being likely to present a direct or indirect
danger to human health, even when used correctly, if used without
the supervision of a doctor
• P medicines which have been safely used for several years may be
reclassified as GSL
Applications to reclassify medicines are evaluated by the MHRA
