Spring is in the air and so are pollen and other allergens, committing seasonal allergy sufferers to itchy eyes, sneezing and a stuffy nose. For severe cases — allergies combined with asthma or symptoms that don't respond to at-home remedies — immunotherapy in the form of shots has become a popular method for lessening the body's reaction to allergens like foods, medicines, pollens and pet dander. Immunotherapy is evolving as allergy drops delivered in liquid form under the tongue become more widespread. UTMB’s Dr. Rana Bonds cautions that oral allergy drops are not yet approved by the FDA because there are still some questions as to the proper effective dosage. As such, the allergy drops are considered an experimental or off-label use and not covered by insurance, though Bonds speculates that will change soon. “I think within two years it will be mainstream,” she said.
