Benzedrex Nasal Decongestant Inhaler

I tried it one time, following directions precisely. It did not stop nasal drip, but it did cause a reaction like a feeling of anxiety or mild panic. I felt something like a craziness. My resting heart rate is elevated. It was very uncomfortable and I feel strongly averse to trying it a second time. I am waiting for it to wear off (4 hours, so far) and wishing there was an antidote. I used the original formula years ago and it worked very well without significant side effects. But the formula changed and the primary ingredient is not good for me. Unfortunately, this is "not returnable".
