Compare 105 allergists & immunologists in St. Peters, MO. Check ratings, insurance, and availability.
The first visit takes 60 to 90 minutes. The allergist will take a detailed history of your symptoms, triggers, and previous treatments. Allergy skin testing is often done during the first visit: small amounts of common allergens are placed on your skin with tiny pricks, and reactions are read after 15 to 20 minutes. The results identify your specific triggers and guide treatment recommendations, which may include avoidance strategies, medications, or immunotherapy.
See an allergist if over-the-counter allergy medications are not controlling your symptoms, if you have asthma that is difficult to manage, if you have had a severe allergic reaction (anaphylaxis), if you suspect food allergies, if you need allergy testing to identify your triggers, if you have chronic hives or eczema, or if you experience frequent sinus infections that may be allergy-related.
Office visit copay: $30-75 · Allergy skin testing: $150-500 · Allergy shots (per visit): $20-50 copay · EpiPen (generic): $150-400
Sneezing, congestion, and itchy eyes from pollen, dust, or pet dander can significantly affect your quality of life. Allergists identify your specific triggers through testing and offer treatment from medication to immunotherapy.
Food allergies range from mild discomfort to life-threatening reactions. Allergists perform skin and blood testing, create management plans, and prescribe emergency epinephrine when needed.
When asthma is triggered by allergens, an allergist identifies those triggers and may recommend allergy shots or sublingual tablets to reduce sensitivity over time.
Chronic hives or swelling episodes that keep returning need specialist evaluation. Allergists determine whether the cause is allergic, autoimmune, or idiopathic and tailor treatment accordingly.
If you have had a reaction to a medication, an allergist can test whether you are truly allergic and identify safe alternatives. This is especially important for antibiotic and anesthesia allergies.
Allergist visits are covered as specialist visits under medical insurance. Allergy skin testing is covered when medically indicated. Allergy shots (immunotherapy) are typically covered with a copay per injection visit. EpiPens and generic epinephrine auto-injectors are covered under pharmacy benefits, though copays vary widely. Ask about manufacturer coupons if costs are high. Some plans require a referral from your PCP.
