It is unsafe for some of our patients to come into contact with people who could have certain infectious diseases.

If your child has been in contact with a person with measles, mumps, chicken pox or a tummy bug during the three weeks before the appointment, please let us know and do not bring them to the hospital. We will instead arrange another appointment as soon as possible.

Please let us know if your child has any other known infection, as they will need to be seen in a designated isolation room. When you arrive at the hospital, please inform reception of the infection.

Please see here for advice on what to bring to your appointment.

Prescriptions for medication

Please take any prescriptions you receive to the Octav Botnar Wing International and Private Care reception desk. Here, reception staff will explain the process of obtaining your prescribed medication.

If you are a self-paying patient, please make payment for medication at the Octav Botnar Wing International and Private Care reception desk and a receipt will be issued. This receipt needs to be shown to the pharmacy department who will then dispense the medication for you.

If you are an embassy or insurance sponsored patient, the pharmacy will fax the cost estimate to the International and Private Care finance team who will request authorisation from your sponsor. We will then arrange collection with you once the payment is authorised. Please note that some sponsors will not fund medications.

It may be the case that you are required to pay for medications but can claim back the cost from your sponsor at a later date.

Repeat prescriptions, supplies and milk

If you require a repeat prescription, please request this during your appointment with the consultant.

However, if you are running low on your child’s medication and cannot wait until your next scheduled appointment, please bring your child’s medication bottles/boxes with you to Caterpillar Outpatients in order for a repeat prescription to be processed.

Please give at least seven days’ notice.

Medical reports and visa letters

Medical reports can be collected from the reception desk on request. If you require a letter to support your visa renewal, please ensure you request this at least one month before your visa is due to expire by contacting your consultant’s secretary.

Cancelling an appointment

If your child is unable to attend a scheduled appointment, please call us on +44 (0)20 7762 6822 to cancel the appointment as soon as possible. We will then ask the consultant’s secretary to contact you with a new appointment time.

Please note that we may be unable to give you a rescheduled date immediately as we do not hold the consultant’s diary.
