How do I get an appointment?

You need to be referred by your GP or another hospital doctor.

  • Changing or cancelling your appointment

    If you need to change or cancel your appointment, please contact us as soon as possible by telephone 020 7188 6399 so that we can offer your appointment to another patient. 

  • Before your appointment

    Please bring a list of any current medications you are taking or creams you are using. Please include prescription medication, medicines you have bought yourself and any alternative medicines, e.g. herbal remedies.

    If you have been treated at another hospital for the same (or any related) condition, please bring any copies of correspondence or investigations with you.

  • What to expect at your appointment

    We make every effort to see you on time, but delays sometimes happen so please do allow plenty of time.

    You will be seen by a member of our team. We will take a full medical history and, to assess your skin problem properly, your child may be asked to undress so that all of the skin (and not just the area(s) affected) can be examined.

    You may also need to have:

    • a blood test
    • skin sampling (taking a swab or scraping to look for skin infections)
    • skin biopsy (taking a small piece of skin under local anaesthetic).
  • After your appointment 

    If the nurse or doctor decides that treatment is necessary, we will send a letter to your GP explaining which medicines you need prescribed.

    Medicines are only dispensed from our hospital outpatient pharmacy if they are needed urgently or cannot be prescribed by your GP.
