There is no such thing as which side effect is greater, budesonide or budesonide nasal spray or cozaaril or fluticasone propionate nasal spray. Each patient’s physical condition is different, and the side effects of the medication also vary, so it is impossible to conclude which drug has more side effects. Budesonide Nasal Spray is mainly used for the treatment of allergic rhinitis and the prevention of regeneration of nasal polyps after the removal of nasal polyps and other treatments, about 5% of the patients who use the drug will have nosebleeds, increased secretion, and less frequently, angioedema, urticaria, dermatitis, itching and so on. It is contraindicated for those who are allergic to any of the components of this drug. Fluticasone Propionate Nasal Spray is mainly used for the treatment of allergic rhinitis, the use of which may cause dryness and irritation of the nose and throat, etc. Less frequently, patients may experience side effects such as allergy and rash after use. It is contraindicated for those who are allergic to any of the components of this drug. However, it is not possible to conclude which drug has more side effects because of the differences in individual physical fitness and dosage of the drug and therefore the side effects produced. It is recommended that patients choose the appropriate dosage as prescribed by their doctor during the use of Budesonide Nasal Spray and Fluticasone Propionate Nasal Spray to prevent adverse reactions due to overdose.
