I have been taking Flonase for two days and have since broken out in hives. I am allergic to ceclor. What shld I do? Other medicines I shld worry abt 

Hives: The Flonase is probably for allergic rhinitis. Have u ever had hives before? If not, then stop the Flonase and see if the hives go away. Then restart the Flonase after the hives are completely gone for 1 week. If the hives recur, then u know it is the flonase. If the hives stay or u have had them before, it is probably something else. You could also try some otc oral antihistamines for the hives. ...Read more
