Allergy Treatments We Offer
We offer a complete range of treatments for food, environmental, and drug allergies. Our approach is based on clinical guidelines and tailored to each patient's needs. From long-term desensitisation plans to day-to-day symptom management, our goal is to help you live confidently with fewer disruptions from allergy symptoms. Below, we explain each of our treatment options in detail.
-
Oral Immunotherapy (OIT)
Oral Immunotherapy is one of the most progressive and personalised treatments for food allergies available today. It works by gradually introducing small, controlled amounts of the allergenic food into a patient’s diet—under strict medical supervision. Over time, the immune system becomes desensitised to the allergen, which significantly reduces the risk of severe reactions from accidental exposure. OIT can be life-changing for individuals with peanut, egg, milk, or other common food allergies. Treatment is always customised and delivered in phases, starting with tiny doses and building up to a maintenance amount, supported by ongoing monitoring and medical review.
-
Sublingual Immunotherapy (SLIT)
Sublingual Immunotherapy (SLIT) is an effective, non-invasive approach to managing allergies to pollen, dust mites, pet dander, and other inhaled allergens. Unlike injections, SLIT involves placing small doses of allergen extract under the tongue, allowing the immune system to build tolerance over time. It’s ideal for patients who experience seasonal or perennial allergic rhinitis or asthma, especially when symptoms are not well managed with medication alone. Treatment typically begins with a consultant-led assessment, followed by a daily home-based routine that is safe for both adults and children.
-
Medication Management
Not every allergy requires immunotherapy. In many cases, a structured medication plan is the most practical and effective approach. Based on a detailed assessment, we create personalised treatment strategies that may include daily antihistamines, nasal corticosteroid sprays, leukotriene receptor antagonists, or adrenaline auto-injectors for patients at risk of anaphylaxis. We review your medication history, address any gaps or concerns, and ensure you’re using the right products at the right dose for your symptoms. For children, we provide parent education and school-safe plans that reduce day-to-day anxiety and improve outcomes.
-
Nutritional and Dietary Management
Food allergies often require strict dietary restrictions—but that doesn’t mean nutrition has to suffer. Our team works with you to maintain a well-rounded diet that avoids allergens without compromising health. We help you identify safe foods, avoid hidden allergens, and manage elimination diets responsibly. For children, we collaborate closely with paediatric dietitians to ensure normal growth and development. Families receive ongoing support, from label reading to school lunch planning, making everyday life easier and safer.
-
Antibiotic Allergy Delabeling
Many patients are labelled as allergic to antibiotics—especially penicillin—based on childhood symptoms that may no longer be relevant. This can limit treatment options and increase the risk of antibiotic resistance. We offer a thorough review process that includes detailed clinical history, skin testing (if needed), and controlled oral challenge procedures. If allergy can safely be ruled out, we update your records and communicate with your GP and pharmacy to remove the outdated label. This gives you access to the most effective antibiotics if and when you need them.
-
Complementary Therapies
Complementary therapies can play a helpful role in allergy care—when used alongside conventional treatments. We advise on clinically informed options such as nasal saline irrigation for rhinitis, HEPA filtration for dust and pollen, and environmental control measures at home. For patients dealing with chronic symptoms or allergy-related anxiety, we also discuss supportive approaches that address sleep, stress, and overall wellbeing. All recommendations are based on individual needs and scientific evidence.

Frequently Asked Questions
-
There’s no one-size-fits-all answer. For some patients, avoidance and medication are enough. Others benefit from immunotherapy (OIT or SLIT) to desensitise the immune system. The best treatment depends on your allergy type, severity, lifestyle, and health goals.
-
Yes—when delivered by trained professionals. OIT must be supervised by a specialist allergy team. It’s commonly used for peanut, milk, or egg allergies in children and has shown good success in improving tolerance.
-
Both OIT and SLIT are long-term treatments. OIT typically involves a buildup phase followed by daily maintenance, often lasting several years. SLIT is generally taken daily for 3 to 5 years, depending on response.
-
Yes. We see patients of all ages and offer tailored treatment plans for infants, children, teenagers and adults.
-
We often treat patients with multiple sensitivities. Your consultant will design a strategy that takes all your triggers into account.
