Founded in 2007, All-American Allergy Alternatives, LLC is a specialty compounding pharmacy that provides custom formulated sublingual immunotherapy (allergy drops) and oral mucosal immunotherapy (allergy toothpaste) by prescription. Allergy immunotherapy treats the cause of your allergies, not just the symptoms. It builds tolerance by exposing the immune system to small amounts of allergen on a regular basis. Allergy Immunotherapy may also have important therapeutic and preventative effects on conditions that often go along with allergies, like chronic sinusitis or asthma.
