How do allergy drops work

On the other hand, repeated exposure to small but increasing doses of allergen desensitizes your immune system. Eventually, your body becomes tolerant of the allergen, so you get fewer or less severe symptoms when exposed to larger amounts of it.

A comprehensive review of published studies revealed there is a lot of good evidence that allergy drops are safe and effective for treating allergic rhinitis. A paper reviewing the safety of immunotherapy used to treat allergic rhinitis showed the chance of severe reactions is much lower for allergy drops compared to SCIT allergy shots.

A review of published studies showed that symptom relief continued for two to three years after allergy drop treatment was stopped after being taken for three years. A lot of research has been done using allergy drops to treat a variety of allergens, but more is needed to determine its overall safety and effectiveness. Currently, all allergy drops approved by the FDA are in tablet form. In the United States liquid drops are still used by some doctors but only as off-label drugs. Most allergy drops are taken every three to seven days for three years.

Some people continue without symptoms indefinitely, but most have to start another course of allergy drops after two or three years because symptoms return.

In general, all of the studies show a decrease in symptoms and need for medications with some evidence that it prevents new allergies, and some evidence that it can decrease asthma development in children.

Both allergy drops and allergy shots work by changing the way your immune system works. The difference is in the way in which we expose your body to things you are allergic to. For allergy shots, the way we expose your body to things you are allergic to is by using needles to inject these things into your skin to allow your immune system to react.

For allergy drops, the way we do this is through exposure under your tongue. Allergy shots work well, but require frequent visits to a doctors office for the shots. This is why many patients elect to use allergy drops instead. There have only been a few head to head comparison studies between the two, but in nearly all the studies, both allergy shots and drops have been shown to be effective in reducing symptoms and the need for medication in allergy patients.

The other method of immunotherapy is sublingual immunotherapy via allergy pills. There are a few FDA approved allergy immunotherapy pills, however, these only work for a specific allergy like ragweed or dust mites. These are good for patients that only have one main allergy. When your body is exposed to something that is not supposed to be there, like a virus, or something that causes an allergy like pet dander, your body sticks an antibody on it.
