Schedule 5 (CD INV POM OR CD INV P):
examples?
- Preparations of certain CDs (such as codeine, pholcodine and morphine) that are exempt from full control when present in medicinal products of specifically low strengths
What is ‘Safe custody’ of controlled drugs?
- Certain Schedule 2 or 3 CDs must be stored securely under Schedule 2 of the Safe Custody Regulations
- Pharmacies, private hospitals and care homes keep relevant CDs in a ‘locked safe, cabinet or room which is constructed as to prevent unauthorised access to the drugs’.
Safe custody (for info)
- Some organisations create SOPs stating that Schedule 3, 4 and 5 should be handled in the same way as CDs in Schedule 2.
- When CDs requiring safe custody are not kept securely (e.g. during the dispensing
process), they must be under the ‘direct personal supervision’ of a pharmacist. - Access to CDs (including handling of ‘CD keys’) should be documented
- Safe custody applies to patient-returned, out of date and obsolete CDs until they can be destroyed
Which schedule drugs must be kept under safe custody:
The Controlled Drugs that must be kept under safe custody are:
* Schedule 1 drugs
* Schedule 2 drugs except for some liquid preparations and quinalbarbitone (secobarbital)
* Schedule 3 drugs unless exempted under the Misuse of Drugs (Safe Custody) Regulations 1973
Common exemptions include:
* Gabapentin
* Mazindol
* Meprobamate
* Midazolam
* Pentazocine
* Phentermine
* Phenobarbital
* Pregabalin
* Tramadol
* Common Schedule 3 CDs which require safe custody include temazepam and buprenorphine
What are the Prescription requirements for Sch 2 and Sch 3 CDs? (7)
- Signature
- Date
-
Date when it was signed.
* CD prescriptions are valid for 28 days after the ‘appropriate date’ on the prescription.
* The appropriate date is either the signature date or any other date indicated on the prescription (by the prescriber) as a date before which the drugs should not be supplied – whichever is later
* The 28-day restriction includes any owing balances. - Prescriber’s address
-
Name of CD (not legally required)
* It is good practice to write the name of the medicine in full -
Form
* The formulation must be stated; the abbreviations ‘tabs’ and ‘caps’ are acceptable. It should be clear and unambiguous if the prescriber intends a supply of m/r s/r -
Strength
* The strength only needs to be written on the prescription if the medicine is available in more than one strength.
Record keeping and Controlled
Drugs registers
Running Balances and Stock Checks:
* Irregularities or discrepancies can be identified as quickly as possible.
* Should be at least once a week
* Running balances for liquid CDs can be affected by overage, residue and spillage
* Liquid balances should be undertaken to confirm the balance on completion of a bottle.
* Stock checks should be recorded, signed and dated (ideally two people should carry out checks)
* Visually check the running balance each time a CD is dispensed
* A running balance should be maintained as a matter of good practice
* It is intended that once electronic registers are in common use this will become a legal requirement
Prescription requirements
The dose must be clearly defined:
examples of legally and not legally acceptable :
Not Legally Acceptable:
* As directed
* When required
* PRN
* As per chart
* Titration dose
* Weekly (frequency not a dose)
* Decrease dose by 3.5ml every four days
* Twice a day
Legally Acceptable:
* One as directed
* Two when required
* One PRN
* Three ampoules to be given as directed (better still – three ampoules to be given over 24 hours as directed)
* One to two when required
Does not automatically indicate clinical appropriateness!
what are some extra prescription requirements?
Total quantity:

Record keeping and Controlled Drugs Registers:

- Must be a bound book with different classes kept in a separate part
- Within each class, a separate page should be used for different strengths and formulations
- Register should be kept at the premises to which it applies
- Kept for two years from the date of the last entry
- Records can be kept in their original form or copied and kept in an approved computerised form
- Copy of the register, and other details of stock, receipts and supplies, must be made available to authorised persons (e.g. a GPhC inspector or CD liaison officer)
upon request.
All entries made in CD registers should be:

- Entered promptly – entries must be made on the day of the transaction or on the following
day - In ink or indelible – entries and corrections must be in ink or indelible (or computerised)
