Hello. Thank you for asking at HCM. I went through your history. I would like to inform you that Diprofos injection contains Betamethasone, which actually a corticosteroid. Were I treating you, I would not suggest you injectable corticosteroid for allergic rhinitis because of long term side effects and complications, especially because many safe and alternative options are available for allergic rhinitis like antihistamines, montelukast, inhaled corticosteroids, etc. (inhaled corticosteroids are much much safer than injectable corticosteroids because they act at local level in the nose) Personally, I would also suggest you allergy testing so that you can identify substances causing allergies to you as well as measures to avoid them. Hope above answer will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health. Thank you & Regards.
