What is sublingual immunotherapy?

Immunotherapy treats the cause of allergies by giving small doses of what a person is allergic to, which increases
“immunity” or tolerance to the
allergen and reduces the allergic symptoms. Unlike injection immunotherapy, which is given as shots, sublingual
immunotherapy is given as drops under the tongue.

How does the process work?

The first step is to confirm a patient’s allergies through allergy testing. Then a custom-mixed vial of drops is prepared for
the patient. The patient takes drops under the tongue daily.
During the first four months, called the escalation phase, the dosage is gradually increased. After that, in the
maintenance phase, the patient takes the same dose of drops each day.

Is sublingual immunotherapy safe?

It is very safe, for both adults and children. Patients take the drops in the convenience of their own homes instead of
going to a doctor’s office every week for shots. The World Health Organization (WHO) has endorsed sublingual
immunotherapy as a viable alternative to injection immunotherapy.

Does sublingual immunotherapy work?

Many published scientific studies have shown that it significantly reduces allergy symptoms.

How long must I continue the treatment?

We recommend that patients keep using the drops for three to five years so that the body will build up a lasting immunity.
