Medicines Update


On Monday 30th November 2015, ketamine will become a schedule 2 Controlled Drug. The change was introduced on the advice of the Advisory Council on the Misuse of Drugs following increasing evidence of harms and concerns around chronic toxicity from long term misuse. This means:


  • Safe custody in CD cabinet is required
  • All transactions must be recorded in a CD register.
  • Prescriptions must conform to the full legal requirements.
  • It must be denatured before disposal in pharmaceutical waste.
  • Hospital wards will need to order stocks using CD order books


Controlled Drug prescription requirements (schedule 2 or 3)

  • All schedule 2 or 3 CD prescriptions are valid for 28 days and must contain the following:
    • Prescriber’s signature
    • Date on which the prescription was signed
    • Patient’s name, address and CHI number
    • name, form and strength of drug,
    • total quantity to be supplied in words and figures,
    • dose stated in full
    • and, where a supply is to be made in instalments, both the instalment amount and interval must be stated, eg supply 10ml daily, supply 20ml on Saturday.
  • It is good practice to include no more than 30 days’ supply on prescription
