In the treatment of allergic rhinitis, avoidance of allergens that trigger the symptoms and drug therapy are essential. Many patients' complaints can be controlled in this way. The most commonly used drugs; antihistamines and cortisone-containing nasal sprays that reduce the effect of allergens. Since the cortisone in the sprays is applied only to the nasal area, it has almost no systemic side effects. Adjunctive measures such as nasal washing are also helpful. In addition to drug therapy, another treatment with proven effectiveness is vaccine therapy with allergens (immunotherapy). In this treatment, allergen substances are given to the body with increasing doses and it is aimed to desensitize the body to these substances.
