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 common side effects include:

  • itching of the ears, mouth, tongue
  • swelling of the mouth, tongue and lips
  • cough or swelling in the throat
  • painful or irritated throat or numb or prickling sensation in the mouth

Get emergency treatmen if you experience: 

  • swelling of the throat, mouth or tongue
  • difficulty swallowing or breathing
  • asthma attack/wheezing
  • hives/itchy rash
  • rapid heart rate
  • fainting
