So, your having issues . . . welcome to my world! :-) My story is not due to a medication, and it is far to involved to get into here. But, I suffer from what appears to be asthma or copd, or something that certainly causes similar symptoms. The short of the story is that I've been sick for 16 1/2 yrs, and still have no diagnosis. In fact, I had to be intubated and put on a ventilater for two days in June. So, I truly understand your concern!
That said, the medicine that you take is called Flonase here in the United States. I'll never understand why they feel the need to give the medicines different names in different companies! It drives me nuts.
So, here are two websites for you to check out. The bottom line is, yes, it is POSSIBLE that the medicine is causing your problem, but it is HIGHLY UNLIKELY!
Scroll down to page 6 of 47 in the pdf document (follow the pdf docuement page numbers) The section heading is called "Other Systemic Effects" It lists 'angioedema'.
First of all, if you go to the emedicine website, don't let the picture freak you out! It is an example of SEVERE angioedema of the lips! It talks about angioedema. Which is swelling of the deep tissues, specifically of the lips/face/tongue. Scroll down to 'Diagnosis' and see the 3rd bullet point. I'll save you the trip if you'd like. It states . . .
"Upper airway – Direct visualization of the uvula or tongue swelling; laryngoscopy is needed to assess laryngeal or vocal cord involvement; document swelling by means of physician notes, photographs, or both"
What the statement above means is that angeoedema can effect the uvula (the hangy-downy thing at the back of your throat), the tongue, the laryngeal (basically from the base of your tongue to the top of your trachea/airway), or your vocal cords. All of which, if swollen can cause you to feel short of breath.
ALL THAT SAID . . . I HIGHLY DOUBT THAT'S WHAT'S GOING ON! It's a VERY RARE side effect of the medicine, that said, the fact that it's mentioned at all means that it CAN happen to someone, and there is no way of telling WHO that someone will be! Therefore, it COULD just as easily be you as anyone else. It's just NOT likely! Be SURE to NOT work yourself up over it! It's CRITICAL to remember that you cannot seperate the mind/body connection! As I have been so reminded of the years, the mind IS the body!
Breathlessnes, or dyspnea (the medical term) will absoultely cause anxiety, which will absolutely cause your heart rate to go up. IN FACT, anxiety can CAUSE breathlessness! It can ALL be wrapped up in one nice neat package. BUT, it may be something else. If you've had this problem before, were you using this nasal spray back then? From your statement above, it doesn't sound like it. But it DOES sound like maybe your doctor should look into doing some other tests. Just to be sure. You have the RIGHT to ask that he look into it, perhaps by running some tests like PFT's (pulmonary function tests), or perhaps an ECG which checks the rate and rhythm of your heart. Anxiety can definetly be a diagnosis of exclusion, meaning that you rule out the obvious other problems that could be causing your symptoms. The most important thing is that you are TOTALLY honest with yourself and your doctor about your symptoms and how you feel both physically, but also mentally and emotionally. Like are you experiencing an unusual amount of stress at work or at home of late? Are you having relationship problems with someone, or financial issues, etc. I'm NOT suggesting that you are, just suggesting that you give that serious consideration.
I'm certainly no doctor! These are merely ideas and food for thought.
So bottom line; to answer your question . . . yes, the medication CAN cause the problem you describe. BUT . . . AGAIN it is HIGHLY unlikely. . .
Talk to your doctor, let him/her help you figure it out. You might want to change medications just to be sure it's not the medicine causing your problems.
Hope this is helpful for you, but more than anything, . . . I hope your feeling better SOON!!!
