allergy drops are more commonly used in europe than in the united states. the allergy drop method is currently being investigated particularly for those allergic to many different pollens (polysensitization). in my opinion the allergy drop method is still investigational but may offer an exciting new approach to allergy vaccine once more is learned on how to maximize efficacy. i currently recommend the injection form of allergen immunotherapy but am following the results of ongoing research into other modalities
despite three medications my son has horrible allergy symptoms. are allergy drops as effective as shots?
