Hey guys, I have severe seasonal allergies and can't take really any allergy meds due to issues with tachycardia and palpitations. My doctor suggested Flonase, but I am allergic to sulfur (used a sulfur mask once and my whole face swelled huge, used to have to brush me teeth with sulfur water and my entire mouth would get blisters) and I noticed that Flonase contains sulfur in its makeup. Can I use it?
