My uncle used Nasal Corticosteroids(Beconase) for 20 years the first time. When he tried to stop it , he had severe withdrawal symptoms, (Irritability, hyperexcitability, anxiety, stress, frequent urination, dyspnea, weight loss etc). His Nasal allergies and polyps returned after a while so, this time he tried Floxanase. After three moinths, he is trying to stop it, but the same problems/withdrawl symptoms are re-appearing, even though he is using the tappering method...
