Sublingual and subcutaneous immunotherapy are both proven to be effective ways to target the source of allergies. Studies have shown the sublingual method to have a lower risk for anaphylaxis, allowing it to be administered from home. As a result, sublingual immunotherapy can save patients time, as well as potentially hundreds of dollars in co-pays.
