• Sublingual Immunotherapy(SLIT)

Sublingual Immunotherapy(SLIT) is an effective way to help reduce your allergy symptoms and prevent new allergies or asthma from forming. A skin prick test is performed to determine which substances are causing the symptoms (i.e. dog dander, tree pollen etc.) and a personalized formula is created for you containing the irritating substances. This liquid formulation is taken under the tongue at very small doses to help your body slowly mount an immune response and build tolerance to the allergen. Over a period of four to six months(build-up phase) the dosage is gradually increased to a maximum dose where the patient will remain (depending on symptom severity) for up to two years(maintenance phase).


Currently, more research is being conducted using SLIT for eczema as well as food allergies, with results looking promising. Patients at any age can benefit from this therapy, but you should discuss with your doctor through a thorough health history to ensure sublingual immunotherapy is right for you.


Who benefits from this therapy?

Adults and children can benefit from this therapy. If you have environmental allergens, hay fever, allergic rhinitis, or asthma. It may also be effective for children with eczema and those will oral allergy syndrome.

What does the test entail?

Much like going to an allergist, several allergens will be tested by pricking the skin (on the forearms). Over 15 minutes the arms will be monitored to see if a raised wheal develops where the skin has been pricked.

How long do I take the SLIT?

There is a build-up phase that last up to several weeks where we slowly increase the dosage over time. Then we move into the maintenance phase once allergen tolerance has been achieved and where the highest dosage is taken.

Are there any risks or side effects?

Yes, but usually very mild. Most common is itching of the mouth and stomach upset, generally when first taking the therapy, or at a dosage increase. Very rarely it can cause an anaphylactic reaction so the first dose is always taken with your doctor.

Who should not take SLIT?

Those who have severe, uncontrolled asthma, patients on beta blockers, if you’ve had an anaphylactic reaction to immunotherapy in the past, or if you have any other unstable condition(such as heart conditions).
