Headquartered in Erie, Pa., Direct Allergy is a company that provides physicians with customized immunotherapy treatments for allergy sufferers. Immunotherapy is a process that helps desensitize an allergy patient to the indoor and outdoor allergens that trigger symptoms, such as itchy, watery eyes and sneezing. An ideal alternative to expensive, ineffective over the counter allergy medications, immunotherapy completely eliminates allergies, helping allergy sufferers spend more time doing the things they love. Physicans benefit from offering a wider range of in-house services that lead to increased clientele and happier, healthier patients.
