- Side Effects: mainly local reactions such has itching or burning of the mouth or lips and less commonly, gastrointestinal symptoms. These reactions usually stop after a few days or a week.
- Treatment Regimen: OIT should be initiated approximately three months prior to the start of allergy season for optimal symptom control, and continued daily through the end of the that season.
- OIT treats only the specific allergen contained in the tablet, and therefore will not address symptoms related to other allergens.
