Dispensing prescriptions for hypromellose eye-drops
Concerns over supplies of insulin
The Royal Pharmaceutical Society’s Professional Standards Directorate has received
several reports concerning the dispensing of incorrect strengths of hypromellose
eye-drops. Extra vigilance is required when dispensing prescriptions for preparations
for which more than one strength is available. Pharmacists are advised to check
and recheck that the correct strength has been selected from the dispensary
shelf. In addition, when a prescription is received for hypromellose eye-drops
and the strength is not apparent, the prescriber should be contacted to clarify
the strength to be supplied.

A number of instances have been reported to the Royal Pharmaceutical Society
recently in which incorrect insulin has been supplied to patients, with the
potential to affect control of the patient’s condition. Typically, the errors
have included the supply of porcine insulin instead of human (or vice versa),
the supply of an incorrect strength (eg, Human Mixtard 30 instead of 50), the
supply of an incorrect product (eg, Humalog Mix 25 instead of Humalog) or the
supply of an incorrect presentation (eg, Penfill cartridges instead of pre-filled
pens).
Pharmacists are advised to ensure that insulin products in similar packaging
are segregated in the refrigerator and that careful checks are made before supply
is made to the patient. It may be useful to check with patients that they recognise
the insulin as the one they are expecting to receive.
