Vasovagal Reaction cause an Asthma attack??

I am 44 yrs old. I went for a vitamin therapy IV today (my first). (Maybe like a Myer's Therapy IV?) Only vitamins, b12, b6, vit c, magnesium and sterilized water, etc. I have mild/moderate asthma with no real problems the last few months. The DR put the IV in my hand, found it wasn't working then put into the crook of my inner arm, no problems. It didn't even hurt. I have 4 kids, so TONS of IVs the last several yrs. After 15-20 mins, I felt "funny", faint and started coughing my asthmatic cough. I felt tight. He said it was a vasovagal reaction and discontinued the IV. Can that cause an asthma attack?? he said it did, but, I haven't heard of that. Thanks!

Thank you, Dougie! I too, thought it was a problem with the compound. I read a bit, on a few sites, about how the magnesium in them can cause asthmatic reactions, too.. Again, thank you!

Hello CAT
A difficult question to answer when not there: I answer it for a couple of reasons.
Firstly, "Vasovagal attack or syndrome" is a very generic term usually referring to fainting or near fainting. It implies a slow heart rate; low blood pressure: sweating; and changes in "gut" activity: I have never witnessed an "asthmatic "component or "bronchospasm" as part of this fairly common response: People can have a bronchospasm response without having asthma.
Aside from why the choice was made to get these agents I.V., I would be VERY CONCERNED that this was a "histamine", possibly allergic affect or a direct affect to one or more of the agents used, including any anesthetic used to start the IV.
Of course, an emotional response can trigger both vasovagal and asthmatic triggers: Asthma, is an inflammatory process and what you experienced sounds more like a "bronchospasm", or acute response to something that happened to you; Bottom line: In consideration for your safety, it sounds un-soundly based to proceed with your therapy based upon the assumption offered to You. There are sooooo many potentials here, that would warrant inquiry to satisfy the guarantee of no further adverse effects.
BE CAUTIOUS !!!!!
