What People
Usually Asked
What conditions do you treat at the Allergy Clinic?
We diagnose and treat a wide range of allergic conditions, including allergic rhinitis (hay fever), asthma, eczema, food allergies, drug allergies, insect sting allergies, chronic hives (urticaria), and other immune-related allergic disorders for both children and adults.
How do I know if I need an allergy test?
If you experience frequent sneezing, itchy eyes, persistent skin rashes, breathing difficulties, recurring sinus problems, or reactions after eating certain foods or taking medications, an allergy assessment can help identify the underlying cause and guide effective treatment.
What allergy tests are available?
Our clinic offers a variety of diagnostic tests, including skin prick testing, blood allergy tests, and other specialized evaluations. The most appropriate test will be recommended based on your symptoms, medical history, and clinical examination.
Can allergies be treated permanently?
While not all allergies can be completely cured, many can be effectively managed with personalized treatment plans. Depending on your condition, treatment may include allergen avoidance, medications, immunotherapy (allergy vaccines), biologic therapies, and lifestyle modifications to provide long-term relief.
What should I bring to my first appointment?
Please bring any previous medical records, allergy test results (if available), a list of your current medications, details of your symptoms or allergic reactions, and information about any known food, drug, or environmental allergies. This helps us provide a thorough evaluation and personalized care.
