I'm not quite sure where to post this question. I've been to over 6 doctors and no one is sure what's going on.
A year and a half ago I started Zoloft for social anxiety. Was going OK. I was then prescribed nasonex and allegra (which I have been prescribed before) for allergies that were cropping up - that night, I had a hot flash after a hard workout, developed an anxiety disorder and insomnia for a few months. I stopped taking all drugs and returned to normal for a week. Then I went to a bar, had not too many drinks, went to sleep, woke up, and everything came back again. They found a mild sleep apnea in pursuit of my insomnia issues, but I'm loathe to credit all the problems to that. The apnea has gone untreated. I've been descending into a perceptive abnormality (severe depersonalization) since, though panics and insomnia have since gone away seemingly on their own.
I know, that's a mess of things. But my ultimate question for this forum is pertinent to when it all started, and a reaction I continue to have - antihistamines make me panic. Badly. Not just h1 antagonists, but I noticed it happened with h2 antagonists as well when I took the occasional pepcid complete. The panic I would describe as an inner trembling, sweating, akathisia. I'd never had a panic attack in my life before that night.
I've been chasing this whale for a year and a half now and am mentally losing the battle. My response to histamine antagonists is a red flag for me but no one knows what it is.
