How to desensitize after an allergic reaction

The main methods for managing allergies and achieving desensitization include: 1. **Avoidance of allergens**: Once the allergen has been identified, further exposure should be avoided as much as possible. For example, individuals allergic to pollen should avoid going outdoors during flowering seasons, and those with food allergies should avoid consuming the allergenic foods. 2. **Medication**: Antihistamine drugs can be used to relieve allergy symptoms such as itching and swelling. Topical corticosteroids may also be used to manage severe skin symptoms. Common anti-allergy medications include H2 receptor antagonists (e.g., chlorpheniramine maleate tablets) and glucocorticoids (e.g., dexamethasone). 3. **Desensitization therapy**: For allergens that are difficult to avoid, such as dust mites and pollen, desensitization therapy may be considered. This involves gradually administering increasing doses of the allergen to the patient, enabling the body to gradually develop tolerance and thereby reduce or eliminate allergic symptoms. Desensitization therapy must be conducted under the guidance of a specialist and requires long-term commitment. 4. **Other therapies**: For example, phototherapy—patients who may benefit from exposure to ultraviolet light can be treated using specialized light equipment. Additionally, maintaining healthy lifestyle and dietary habits to strengthen the immune system can also help prevent and alleviate allergic symptoms.
