For Rhinitis "TAKE FLONASE NASAL SPRAY AT YOUR OWN PERIL! After having used it for two days, I suddenly woke up in the middle of the night unable to breathe. For almost a minute, I was unable to get any air into my lungs. My throat/windpipe was totally constricted. It was the scariest moment of my life. Then gradually, I was able to inhale just a little bit of air. Never again will I touch this stuff."

For Allergic Rhinitis "I moved to Seattle in spring, so I started getting allergies. The doctor recommended Flonase for it. It helped get rid of it, but after a while, I started getting this shortness of breath and tightness in the chest area. It felt like I was going to pass out a couple of times. I’m going to stay away from it as that is far scarier than being stuffy."

For Rhinitis "I felt like I was dying. After using Flonase for a month, for the first time in my life, I was experiencing anxiety and panic attacks. Another night, I was awoken by a horrible headache and vomited. The Flonase made it so hard to breathe I could only take shallow breaths, and my heart rate was way higher than usual. The only thing I could focus on was my breath and what's wrong with me. I would have never known it was the Flonase causing this if I didn’t look up the side effects online."

For Rhinitis "Within 2 hours of my 2nd dose of Flonase, I experienced difficulty breathing and had crusting around the openings of my nose. I also had a feeling of extreme restlessness, much like I would imagine restless leg persons are afflicted with. The next morning, I was SOB with minimal exertion and experienced a worsening sore throat and pharyngitis, with difficulty speaking above a whisper."

For Rhinitis "I have been a long-term user until recently. At first, Flonase worked like it should. Until recently, being diabetic as well, I started becoming very tired and nauseated. After using it at night, trouble breathing, wheezing, and, worst of all, oral thrush started. Since then, my doctor stopped the medication due to serious side effects. My system straightened up within a couple of days after stopping, and I feel a lot better than ever."

For Rhinitis "I already suffer with anxiety and allergies. I've tried this the last two days, and my anxiety levels have shot through the roof: palpitations, shortness of breath, elevated blood pressure. Unable to sleep until the early hours despite taking medication, then on edge all day long, feeling anxious and irritable. If you're already suffering from anxiety issues, I'd be very careful about taking this, if at all. Whether it's had any impact on my nasal congestion, I don't know, because I've been overwhelmed with anxiety."

For Rhinitis "The worst thing about Flonase is that you have to try it for a full week to test whether it works. I just finished that week. It did not work, and I slept terribly because I couldn't breathe. I have a narrow nasal passageway. Flonase did not work."

For Allergic Rhinitis "Cleared my sinuses right up, but gave me five other problems: headaches, joint soreness, rapid heart rate, shortness of breath, blurred vision. This stuff is going right in the garbage can."
