Oral Immunotherapy

Daily Dose Program

At Modena Allergy + Asthma, our Daily Dose Oral Immunotherapy (OIT) Program is designed to help patients achieve lasting desensitization from food allergies, giving them greater freedom and confidence in everyday life.

With three personalized treatment pathways, we tailor care to each patient’s individual needs and goals:

Low Dose OITTraditional OITSublingual Immunotherapy

We treat the Top 9 food allergens and more, including peanut, tree nuts, milk, egg, wheat, soy, sesame, fish, and shellfish.

The Daily Dose Program goes beyond treatment, providing families with added support throughout their OIT journey, including a 24/7 on-call nurse line, community events, an OIT tracking app, and single or multi-food treatment options.

Patient Testimonials

I was with a condescending awful allergist for years. Finally made the switch. So happy I did. Ricky took good care of educating me and gave me options and recommended tests. So happy to have someone listen and offer choices.

Ready to See an Allergist?

Get Answers with Expert Allergy Testing and Evaluation.

If you suspect you or your child may have an allergy, an evaluation with a board-certified allergist can help provide answers before you make major changes to your diet, lifestyle, or environment. By reviewing your symptoms and medical history and using targeted allergy testing when appropriate, an allergist can help determine whether a suspected allergen is actually causing your symptoms—and help you avoid unnecessary restrictions based on assumptions or unvalidated testing.

For suspected food allergies, evaluation typically includes a detailed reaction history and targeted food allergy testing. When appropriate, a supervised oral food challenge may be recommended to help confirm or rule out a food allergy.

If a food allergy is diagnosed, your allergist can create an individualized management plan that may include allergen avoidance, prescribed epinephrine, an emergency action plan, and discussion of available food allergy treatment options. While no evaluation or treatment can eliminate all risk, the right diagnosis can help you better understand and manage your allergies with confidence.

What Should I Bring to My Appointment?

Your first visit helps us understand your symptoms and health history so we can plan your care; if available, please bring:

  • A list of your current medications, inhalers, or epinephrine
  • Previous allergy or asthma test results
  • Relevant records from your primary care doctor or other specialists
  • Any questions or concerns you’d like to discuss
Don’t have everything? That’s okay. We can still get started and determine what information or testing may be helpful.
