how many allergy shots to maintenance
First, there's the allergy testing -- multiple scratches into the skin with different allergy triggers to identify what the person is allergic to. Then there's the time involved -- weekly injections for three to five months to gradually build resistance followed by several years of monthly maintenance shots. And there's the pain with each allergy shot. There's also the time it takes for the allergy shots to show noticeable results; usually, several months after those weekly building doses are completed. Relief of symptoms can be seen after a few days of antihistamine pills.
