Can anyone give me some info on the injections, side effects, long term use, how they make you feel when you use them, etc... Thanks

I consider them magic.  As for the side effects - I feel a kind of weird pressure (not really in the chest - just overall) and when that pressure gets to my neck I know the pain will be gone soon.  As I have said before - I actually like the feeling because I know relief is coming.

As to long term side effects, I have done as much research as I can because I had assumed that the reason my old insurance would only give me 4 per month were because they were dangerous.  There are two studies (sorry I do not have a link - I had to pay for the reports) that I found which indicated no indications of any serious long term issues with Triptans, and - even more important - the only take two in a 24 hour period is bunk.  This assumes you don't have other heart issues.  I have taken as many as 5 shots in +/- 36 hours, and they have always worked.  Some feel that the imetrix causes rebounds.  I think that when in the middle of the tempest I just get a lot of hits - and would get no more nor less without taking the injections.  Main reason I try to hold off on using them is cost (same reason the insurance company only paid for 4 per month).  The dang things are spendy even though I get mine from Turkey.

Good luck

Much like everyone else, it has been my go to for aborting an attack. I inject it in my thigh, and the HA goes away anywhere from 7-12 minutes.

The negatives are the side effects. The meds wear off after a few hours, and rebound HAs are much more common. After abusing the drug for years, I noticed that Imitrex has taken its toll on my cognitive abilites [memory, coordination, etc]

My advice would be to only use Imitrex when you aren't close enough to an 02 tank.
