At Amerimmune Clinic, our team of allergy specialists is dedicated to helping patients manage both indoor and outdoor allergies. Whether your symptoms are triggered by common indoor allergens—such as dust mites, pet dander, mold, or cockroaches—or by outdoor allergens like pollen from trees, grasses, and weeds.
When you visit our clinic, our allergists will take the time to understand your full medical history and discuss your symptoms. We offer comprehensive allergy testing, including skin and blood tests, to accurately identify the specific allergens affecting you. Our approach may include environmental control strategies to reduce your exposure, prescription medications, and, when appropriate, allergen immunotherapy. This advanced treatment gradually builds your tolerance to allergens, helping to reduce symptoms over time.
At Amerimmune Clinic, we’re committed to helping you breathe easier and live better by effectively managing your allergies—indoors, outdoors, and year-round.
Every patient’s experience with allergies is unique, and the time it takes to feel relief from allergy treatments can depend on the type of therapy used and the severity of your symptoms.
For many patients, oral antihistamines, commonly recommended, can provide noticeable improvement within one to two hours after a dose. If your treatment plan includes nasal corticosteroid sprays, you may need several days to a week of daily use before experiencing significant symptom relief, as these medications gradually reduce inflammation in your nasal passages.
Decongestants, whether taken orally or as nasal sprays, often work more quickly—sometimes within 30 minutes—but are generally recommended for short-term use due to potential side effects.
For those undergoing advanced therapies such as allergen immunotherapy (including allergy shots), which we offer at Amerimmune Clinic, symptom improvement is a gradual process. These treatments are designed to desensitize your immune system to specific allergens, and it may take several months before you notice a substantial reduction in symptoms. In many cases, your provider may recommend combining different medications or therapies to achieve the best possible results.
It’s important to remember that individual responses to allergy treatments can vary. If you do not experience the expected relief within the usual time frame, or if your symptoms worsen, we encourage you to contact our healthcare provider.
