We hold our outpatient clinics in different locations at Guy's Hospital on different days of the week. Please ensure you check your outpatient appointment letter and/or appointment text message reminder for the correct location of your outpatient appointment.
Nurse-led desensitisation clinic is a treatment for severe allergies that do not respond fully to medical treatment.
We offer immunotherapy for allergy to:
- pollen (hay fever)
- house dust mites
- animal dander (cat and dog)
We also offer immunotherapy for patients who have experienced anaphylaxis and have a proven allergy to insect venom (bee and wasp).
Under exceptional circumstances we are able to offer sublingual (oral) immunotherapy treatment, although strict criteria have to be met before this can be done.
Treatment is initiated in the clinic area under the supervision of our specialist nurses. In the case of sublingual immunotherapy, this is continued at home. We do not currently offer a desensitisation service for food allergies.
Immunotherapy – bee and wasp venom
The desensitisation programme for adults who have had anaphylaxis to wasp and bee stings is a three-year treatment programme, requiring weekly visits to our clinic for the first eight to 10 weeks. After this, the next visit is two to four and then six to eight weeks for the next three years.
Drug allergy clinic
A consultation with an allergy consultant, registrar or clinical nurse specialist takes place to ascertain your drug allergy.
This appointment may also involve skin prick tests and possibly blood tests.
This treatment involves giving the drug by one of the following routes:
- oral (by mouth)
- subcutaneous (injection just below your skin)
- intramuscular (injection into the muscle of your arm)
- intravenous (injection into your vein).
The choice of route depends on the drug being tested, but the oral route is preferred whenever possible. We start by giving you a very small dose of the drug being tested by one of the routes listed above; this may be a diluted sample of the drug to be given intravenously, or a small fraction of a tablet or syrup to be given orally. We will progress by giving you gradually increasing doses of the drug being tested at intervals of 15-30 minutes. Some medications will have longer interval times.
Omalizumab (urticaria) clinic
A consultation with an allergy consultant, registrar or clinical nurse specialist takes place to ascertain your food allergy.
This appointment may involve skin prick tests and possibly blood tests. Please bring and a sample of any foods you think you may be allergic to.
Epi-pen training is also done at this time if deemed necessary.
