General information, not an individual diagnosis. Ask a healthcare professional if you are unsure about your situation.
An allergist may propose desensitisation when allergens cause troublesome respiratory-allergy symptoms. For the discussion, describe when symptoms occur and gather your assessment results. The professional considers this information together before discussing treatment.
Desensitisation aims to help the body tolerate the targeted allergen. Ask about its goal in your circumstances and how it fits with treatments that relieve symptoms and measures to reduce exposure.
The treatment requires regular administration over a long period. The sources describe a commitment lasting several years. Before deciding, ask about the planned duration and what regular treatment would involve in your daily life.
The forms described include injections, preparations taken under the tongue and tablets. Ask which form is being considered for you, its specific instructions and whom to ask questions. A general description does not replace the arrangements for the proposed treatment.
If you also have asthma, ask how the proposal fits with your care. Assurance Maladie describes desensitisation as a possible addition to regular asthma treatment. Do not stop that treatment on your own initiative.
Before choosing, clarify the targeted allergen, the goal and how the outcome will be assessed with the allergist. Discuss any difficulties you foresee with regular long-term treatment. The conversation helps you understand the proposal for your circumstances.
