If you have hay fever, your doctor will give you a tiny dose of the allergen as a tablet. You let it sit under your tongue and then swallow it. Because the dose is so small, your body won't react.
You’ll get more doses of the allergen on a regular basis so your body gets used to it. Eventually, you should have only very mild symptoms when you get the allergen. Or you may not even have symptoms anymore.
