I have seen my GP about this problem and
he has prescribed a nasal antihistamine
spray called, Allecort. I used it one day and
stopped, because it made me feel worse. The dizziness has now turned to lightheadedness for
me. I am currently taking benadryl
-D Allergy & Sinus when I go to sleep and during the day I take Tylenol Sinus Congestion & Pain - Daytime tablets. These drugs seem to be helping, because I have not felt dizzy.
