CPH encourages those with service users to ensure you:

  • have contact numbers for all service users;
  • have communicated with CGL how they can contact you easily in an emergency; and
  • be aware that CGL staff or possibly couriers will deliver the prescriptions to the pharmacy and would be grateful if you could aim not to make them wait long periods of time although recognise your current workload.

If you need any support in ordering or how to encourage service users to take a Naloxone kit, please get in contact with Trudy Sealy on 07881 335213.
