Allergy Drops

A new allergy treatment may help stop runny noses and swollen eyes.

Researchers are now testing an experimental medicine for people who suffer from allergies. It's called sub-lingual immuno-therapy or SLIT, for short.

Instead of an allergy shot, patients put a drop of allergy treatment under their tongue twice a day. Doctors say with the drop, the immune system becomes desensitized to allergens.

"It seems to have local effects on the immune system in the nose, eyes, respiratory tract."

The drops are still being tested and we could see them on the market in just a few years.
