Catheter patency solutions (Formulary)

See guidance on the use of catheter patency solutions.

  • Catheter patency solutions are licensed medical devices rather than medicines; initiation can therefore be undertaken by either a prescriber or registered nurse or midwife with the appropriate training and level of competence; such initiation by a registered nurse or midwife should simply be recorded within the patient’s notes and/or care plan.
  • As they are not licensed medicines they need only be prescribed if a supply is required in the community or where prescribers initiate treatment to be given by others.
  • See also Community Catheter Formulary and Prescribing Notes.
