When to see a allergist
- Year-round or seasonal nasal and eye allergy symptoms
- Asthma that is hard to control
- Suspected food, drug, or insect-sting allergy
- Recurrent infections suggesting an immune problem

Common procedures & tests
What to expect at a visit
Come off antihistamines for several days beforehand if skin testing is planned (the office will advise). Bring a symptom diary and a list of suspected triggers and reactions.
Insurance & referrals
Visits and testing are billed to medical insurance; allergy immunotherapy is generally covered but involves frequent visits over months to years.
Frequently asked questions
- How does allergy immunotherapy work?
- Gradually increasing doses of an allergen train the immune system to react less over time. It is given as shots or, for some allergens, under the tongue.
- Can adults develop new allergies?
- Yes — allergies can begin at any age, including adult-onset food and environmental allergies.
