Allergy Drops (Sublingual Immunotherapy or SLIT)
Sublingual immunotherapy, or SLIT, is a comprehensive term for tablets or drops placed under the tongue as part of an immunotherapy program to desensitize patients to common allergens. SLIT is safe and effective and does not require injections like allergy shots. These therapies can effectively treat allergies caused by dust, pet, dander, pollen, and other environmental allergens, amongst other allergies. Much like any immune therapy, including allergy shots or allergy tablets, it takes time for these sublingual options to work, and patients may start noticing improvement in symptoms after a few months. It is worth noting that allergy drops are formulated specifically for the patient and are not FDA-approved. Four tablets for single allergens, on the other hand, are FDA-approved.
The Safety of Sublingual Allergy Treatment
Immunotherapy is very safe and can help avoid the most severe reactions to allergens. This therapeutic intervention can be considered for any well-selected patient, whether administered as a shot, a sublingual tablet, or a drop. When comparing safety profiles, it’s worth noting that while allergy shots have caused severe reactions and even death in the past, we do not know of any fatalities associated with allergy drops.
