Controlled Drug Requirements in UK Pharmacies
Controlled drugs (CDs) remain one of the most heavily regulated areas of pharmacy practice in the UK. Whether operating a community pharmacy, a distance-selling model, or a pharmaceutical warehouse, robust processes around procurement, storage, record keeping, and destruction are essential to meet both legal and professional standards.
For pharmacy owners and superintendent pharmacists, compliance is not just about avoiding enforcement action—it is central to patient safety, governance, and maintaining GPhC registration.
Understanding Controlled Drug Schedules
Controlled drugs are categorised under the Misuse of Drugs Regulations 2001, which divide substances into five schedules based on their therapeutic use and potential for harm.
Key schedules relevant to pharmacy:
- Schedule 2 (CD):
Morphine, oxycodone, fentanyl, methylphenidate
→ Full CD requirements apply (register, safe custody, witnessed destruction) - Schedule 3 (CD No Register):
Buprenorphine, midazolam, temazepam
→ No register required, but safe custody rules still apply (with some exemptions) - Schedule 4 (Part I & II):
Benzodiazepines (Part I), anabolic steroids (Part II)
→ Minimal CD requirements in community pharmacy - Schedule 5:
Low-strength preparations (e.g. codeine linctus)
→ Limited regulatory requirements
Understanding which schedule a medicine falls into determines the level of control required across the supply chain.
Controlled Drug Register Requirements
Maintaining an accurate and compliant CD register is a legal requirement for Schedule 2 drugs and certain Schedule 3 drugs (where applicable in specific settings).
Key requirements:
- Must be a bound or approved electronic register
- Entries must be made on the day of the transaction or the next day
- Separate pages required for each drug strength and formulation
- Entries must be chronological and indelible
- A running balance must be maintained
Required entry details:
- Date supplied or received
- Name and address of supplier or recipient
- Quantity obtained or supplied
- Running balance after each transaction
- Prescription reference (where applicable)
Electronic CD registers are widely used but must meet audit and security standards, including access control and audit trails.
Safe Custody and Storage Requirements
Controlled drugs subject to safe custody must be stored in a locked CD cabinet that complies with regulatory specifications.
Core requirements:
- CD cabinets must meet the Misuse of Drugs (Safe Custody) Regulations 1973
- Fixed securely to a wall or floor
- Access restricted to authorised personnel only
- Keys must be held securely and access controlled
Pharmacies should implement clear SOPs covering:
- Key holding responsibilities
- Shift handover procedures
- Access logging where appropriate
Failure in safe custody is one of the most common issues identified during GPhC inspections.
Ordering and Requisition Requirements
Schedules 2 and 3 CDs must be obtained using a valid controlled drug requisition.
Key compliance points:
- Use of approved requisition forms (e.g. FP10CDF in England)
- Inclusion of:
- Name, address, and profession of requisitioner
- Purpose of requisition
- Total quantity requested
Wholesalers and suppliers must verify requisitions before supply. Pharmacies must retain copies for at least two years.
Dispensing Controlled Drugs
Dispensing CDs carries additional legal and clinical checks.
Prescription requirements (Schedule 2 & 3):
- Patient name and address
- Drug name, form, and strength
- Total quantity in both words and figures
- Dose instructions
- Prescriber signature
- Valid date (28-day validity period)
Pharmacies must also:
- Confirm prescription authenticity
- Check for alterations or irregularities
- Ensure clinical appropriateness
Destruction and Denaturing of Controlled Drugs
Expired or unwanted controlled drugs must be destroyed in accordance with strict procedures.
Key rules:
- Schedule 2 CDs:
Must be destroyed in the presence of an authorised witness (e.g. CDAO-appointed person) - Schedule 3 & 4 CDs:
Do not require a witness (in community pharmacy), but must still be denatured appropriately - Use of denaturing kits is standard practice
A record of destruction must be kept, including:
- Drug details
- Quantity destroyed
- Date
- Witness signature (where required)
Standard Operating Procedures (SOPs)
GPhC standards require pharmacies to have robust, up-to-date SOPs covering all aspects of CD management.
Essential SOP areas:
- Ordering and receipt
- Storage and access control
- Dispensing procedures
- CD register management
- Stock checks and reconciliation
- Incident reporting
- Destruction processes
SOPs should be:
- Regularly reviewed and version-controlled
- Read and signed by all relevant staff
- Aligned with current legislation and best practice
Stock Checks and Governance
Routine CD stock checks are essential for identifying discrepancies early.
Best practice:
- Weekly balance checks for Schedule 2 CDs
- Full audit at regular intervals (e.g. monthly)
- Immediate investigation of discrepancies
- Documentation of all checks
Unexplained discrepancies must be escalated and may need to be reported to:
- NHS England Controlled Drugs Accountable Officer (CDAO)
- GPhC (if serious concerns arise)
Common Compliance Risks in Pharmacy
During inspections, regulators frequently identify:
- Incomplete or inaccurate CD registers
- Missing running balances
- Poor cabinet access control
- SOPs not followed or outdated
- Delays in recording transactions
- Inadequate destruction records
Addressing these proactively reduces regulatory risk and strengthens governance frameworks.
Regulatory References and Guidance
For authoritative guidance, pharmacy teams should refer to:
