For Allergic Rhinitis "I am horrified after seeing these negative reviews and mad at myself for trusting many doctors for many years. They kept me on Flonase for 15 years. I was on it constantly, as well as Allegra. I can’t count the number of times I asked, “Are you sure a steroid nasal spray is okay to use every day and won’t have side effects?” The resounding answer was always no, perfectly safe. I kept taking it all those years because I thought rhinitis was the source of my headaches. Flash forward, I got very sudden vision problems. I had always had 20/20 vision. The optometrist said it was age (I don’t think 45 is that old). Then came years of increasingly debilitating headaches that no medication (not even narcotics) would touch. I never correlated this to Flonase. Three weeks ago, a 10/10 headache woke me up, I vomited, and almost went to the ER (again) because of dizziness. I made an appointment to get an MRI, then found this site! I am FURIOUS. A CLASS ACTION LAWSUIT IS NEEDED!"

For Allergic Rhinitis "STAY AWAY FROM THIS. I started taking it 2 years ago. The doctor recommended this for allergies and sinus problems. I can't believe it took me this long to realize all the problems I've been having were because of this stuff. I started with heart palpitations, pressure in my neck, high blood pressure, and really bad vertigo. I ended up in the ER twice, and I started to notice every time I took it, I was feeling anxiety and I had panic attacks. I never suffered from any of these problems. They recommended it again after my last vertigo attack, and I was feeling worse every time I took it. I started reading the reviews on another page. I am so glad I found other people with similar symptoms. Horrible. DO NOT TAKE THIS. It's in the trash now."

For Allergic Rhinitis "Started taking Flonase and Claritin every day for sinus congestion and fluid in my ears. After using it for 2-3 weeks, my sinuses were clear and the fluid in my ears changed to confusion, brain fog, and a little dizziness. As a result, full-blown anxiety. Never experienced any anxiety in my life. Reading similar posts on here. My question is how long after quitting Flonase and Claritin will I feel better? Day 8 right now and making very little progress. Any comments?"

For Allergic Rhinitis "I took Flonase for a few days in a row, and it has now been 3 months since I’ve been off of it, and I am still struggling. It has turned my life upside down. I’ve had anxiety, depression, weird debilitating headaches, strange skin sensations, neurological problems such as tremors, vibrations, severe burning skin all over, hot flashes, cold chills, weakness, dizziness, nausea, numbness, tingling, blurred vision, and uncoordinated movements. This all started when I took Flonase several days in a row. In the past, I had taken it about once a month, so I didn’t notice the side effects as badly. The anxiety and depression have eased up a lot, and the headaches are a little less frequent. The burning feeling is still terrible. I still get very weak, and the skin sensations are still there. It feels like I’m swollen all over, even though there’s no visible swelling. Warn everyone you know about this."

For Rhinitis "Took this for two days for dizziness. The first day it worked, but the second day it didn’t do anything. My anxiety was through the roof, I had heart palpitations, and my speech was off, along with using my hands to talk, which is not normal for me. It felt like I was on drugs, which I found embarrassing."

For Rhinitis "I recently had a triple bypass procedure. I have always had seasonal allergies and sinus issues but the cardiologists and my primary physician recommended I use Flonase rather than regular antihistamines and decongestants. I didn’t realize it, but after taking it for a while, along with other meds since my heart surgery, I developed severe dizziness every morning. This lasted until late afternoon. I blamed it on all the meds I was taking but after they took me off all of the “heart” drugs, I finally realized it was the Flonase causing my problem! In the trash!"

"Yes, I use Flonase for only three days due to a cold I have and allergies. The worst ever caused my nose to burn my nose and lips. It left me a heavy scab that I can't get rid of. It makes you dizzy. It is nasty. I recommend do not use. Instead, go buy generic Claritin to be on the safe side. Don't believe everything doctors say or want to sell you."

For Rhinitis "Takes a few days, and then it helps with congestion and stuffiness short term. I do not stay on it past 1-2 weeks due to side effects, prone to infection, dizziness, etc. Overall, a good med for me."
