Hi ,I have had this condition in the past but it seems to be in remission now for the last 7 months.
I am a young adult.
I have autoimmune diseases as well ,reiters syndrome (reactive arthritis),Ankylosing Spondylitis ,Asthma ,reoccurring iritis
(autoimmune eye disease).
Everything but the iritis seems to be in remission, I have spent a couple of months on predisone eye drops to get that under control.
My Idiopathic Anaphylaxis started around May 2009 after starting a course of erythromycin antibiotics.
I never had any allergy in my life before this apart from a little asthma.
When I took the first two tablets of erythromycin I just knew something was wrong (light sensitivity / light headiness / hot flushes / dizzyness) but just thought the body was getting used to the medication.
The following day I woke up feeling fine and had breakfast and another tablet and thats when all hell broke loose and I was sent to ER for anaphylaxis treatment (predisone / Promethazine injection).
I came right after a week but after drinking some beer at a friends place the reaction re-occured and I was back to square one.
From that day on the anaphylaxis symptoms were present if I did not take daily the prescribed meds
(promethazine tablets & ranitide) and spent a 3 months living like a zombie from the antihistamine promethazine.
Even with daily treatment I would get surges of inflammation and swelling around the body.
I started taking zyrtec on the third month so I didnt feel sedated but it was not as effective so I had promethazine as a emergency backup.
Never took predisone after the first week.
Doctor never prescribed it he thought it was better managed with antihistamine without steriod dependancy.
I never really got hives just a little on the back between episodes but had more of the dizziness , swelling ,extreme heart rate and blood pressure drop symptoms.
So for a 8 months I ate vertually nothing but rice and tuna.
Stopped drinking everything but water including alcohol (this was one of the worse triggers).
The weird thing is that most things would make it worse but if I didnt take them I still would get reactions.
I was skin tested and everything but dust mites came up as clear ?
The dust mite skin test gave me a rather severe welt on my arm for a couple of weeks so I am allergic to these.
What I couldnt understand is why I still had reactions even if away from dust mite allergins.
Dont know the allergist just said it was idiopathic and my immune system in a severely alert state ready to react to any foriegn antigens (compounds).
He also said my body may also be allergic to itself ?
After 9 months my symptoms settled and I tampered off the antihistimes and started to eat foods other than rice and tuna.
By the twelth month I no longer took any allergy related prescription drugs and ate all the food types I used to.
I havnt had a reaction since but it has left me with something to remeber it by and that is hearing loss.
Not to bad but enough to be aware of the fact.
That is life.
I hope and pray you all get better soon.
Dave.
