LA CROSSE, Wis. -

A type of allergy relief already offered in the Coulee Region is getting positive reviews.

Researchers at Johns Hopkins University reviewed dozens of past studies and found that under-the-tongue drops, which are offered at Allergy Associates of La Crosse, are a safe and effective alternative to a weekly allergy shot for boosting immunity.

The Food and Drug Administration has not approved taking the drops under the tongue, also known as sublingual immunotherapy, but doctors in the U.S. use the drops off-label for some patients.

"With sublingual immunotherapy, we're using the exact same extracts that are used for injection immunotherapy and those are approved by the FDA. So using those drops is an off label use of the FDA approved extracts. And we're very, very careful with how we test, determine the level of allergies a patient has and then tailor their treatment to that level," said Allergy Associates Practice Executive Jeff Kessler.

Kessler says this study is further validation that under-the-tongue drops are safe and effective.
