Neo-Synephrine side effects

I've been using it for 5 months. i go through a bottle in a week and a half and every time i try to get off my nose gets so congested it hurts and makes it hard to breathe. if anyone has any tips on how to get off let me know

dysphagia -- apparent loss of ability to initiate pharyngeal stage of swallow with solids secondary to decreased ability of receptors in tongue base to recognize solid bolus

I took Neo 12 hour twice in the prescribed 24 hour period. I noticed the next morning that my heart rate was elevated upon rising, and while taking a shower, noticed that I was having lots of palpitations or "skipped beats" followed by a refreshing feeling...you know, the feeling you get after you hold your breath for a minute and then let it out and take a deep breath. I didn't think the episode was due to the Neo 12 hour, but changed to the Neo 4 hour because I wanted the stuffy head/nose to clear up sooner than 12 hours. I wanted to know if the Neo could interact with Sudafed or not, and if so, could it cause this problem to be worse than just one of these meds by itself?

This may answer alot of questions. I've been using neosynephrine for 40 years. One to two bottles a week. Started with 1/2%, I think that's what it was, and graduated in no time to 1%. I've never been able to get off for more than a couple of days. I have had a skipping heartbeat for 33 years, which may or may not be due to the neo. Sometimes is skips pretty steady, and other's just occasionally. I had a stress test last week that came back positive, and went for a heart cath. It showed no blockage whatsoever, so it was a false positive. Due to all this, I decided to stop last Wed., so I diluted my nosedrops in half with Saline Nasal solution. Since about the 3rd day, Sat., I have had all kinds of symptoms, including low blood pressure, fuzzy in the head, and not able to think straight. Today it is mainly the fuzzy in the head. Almost like you're somewhere else looking in. I will continue to try and get clear off, if anyone knows anythink else about getting off, would appreciate knowing the symptoms.

Short of recommending that someone see an ENT Specialist, what should someone do if they have been using neosynephrine for 3 years. I understand about the rebound effect. What can happen if someone continues to use this many times a day?

My Ophthalmologist used Neosynephrine to dilate my eyes. I experienced irregular rapid heartbeat which continued for hours. After 8 hours, I then went to the hospital emergency room and was released about 3 hours later. I left with a slight irregular heart beat after taking beta blockers while being monitored.

My eyes were dilated with Neosynephrine and it caused me to syncope (faint). The opthamologist sent me to the hospital for tests and it was discovered that the nerve endings around my heart are very sensitive to Neosynephrine and Nitroglycerine. They cause my already low blood pressure to drop and cause syncope. Not a common accurrence.

I am asking this question on this site and I can not find the answer to it?
What does Neosynephrine actually do and what are the side effects?
Thanks for you help
