Sublingual Immunotherapy (SLIT)
Now Available in Mission Viejo

Residents of Mission Viejo dealing with year-round allergies to Southern California’s coastal winds, oak and sycamore pollen, and indoor triggers like dust mites can now access a convenient, needle-free path to lasting relief. Pacific Allergy & Asthma offers sublingual immunotherapy (SLIT) — an FDA-supported, clinically proven treatment in which small doses of allergen extracts are placed under the tongue daily. Unlike traditional allergy shots, SLIT can be administered from the comfort of your home after an initial supervised dose, making it an ideal solution for busy Mission Viejo families. Dr. Tyler Basen, our board-certified allergist and immunologist, designs each personalized SLIT treatment plan based on comprehensive allergy testing, so you receive targeted relief for your specific triggers. Patients typically experience a meaningful reduction in symptoms and reduced reliance on daily medications over time — helping you breathe easier and enjoy everything Mission Viejo has to offer, from Oso Creek Trail to the Norman P. Murray Community Center. Contact Pacific Allergy & Asthma today to find out if sublingual immunotherapy is right for you.
