The immune system is the target of immunotherapy. The aim is to prevent or suppress allergic symptoms, such as allergic rhinitis, through repeated administration of the allergen. The effect of sublingual immunotherapy is thought to be mediated through local and systemic immunomodulatory mechanisms (immune deviation) including changes in allergen specific antibodies and regulatory T- cells leading to long-term tolerance development.
The most commonly reported side effects are:
- itching of the mouth, lips, or tongue
- swelling under the tongue
- throat irritation.
Do not take if you:
- have severe or difficult to control asthma
- have ever had a serious allergic reaction to ragweed allergy shots, tablets or drops
- are taking beta-blockers (a medicine for heart conditions, such as high blood pressure)
