One shot Haloperidol long term effects?

Dear All,

I got injected only once with Haloperidol, got it az ER as tranquilizer (even though I only felt uneasy...) That caused me to fell asleep, I woke up in a couple of hours, only a bit of twitching in my shoulder, but a pill took care of that for good. This happened a year ago.

I read various articles on the internet that Haloperidol (and basically psychiatric drugs) can cause brain damage/brain volume shrinkage.

This stuff got me worried as a would be software engineer I wish to dedicate my whole life to learning IT/programming and I need my brain in top shape to do so. I got no other medications than haloperidol and that pill afterwards.

Shall I be worried about possible brain damage? I admit those articles were about persistent use but I'm still worried.
As for the long term effect, does this one shot effect the brain/dopamine levels/whatnot permanently?

For the record: Tests I performed recently: an official Mensa adaptive IQ test on which I scored no mistake, giving me an IQ above 125, a test for superior IQ would be needed to evaluate it accurately.

For my balace I usually do weighted single leg squats, I rarely fall on my bottom. For dexterity I play the clarinet and the saxophone, my technique has no more flaws than it used to have. For memory, I'm an Eastern-European university student, we have to cram everything and so far so good, I had the two semesters with all my credits completed with ease.

I understand this all sounds most hypochondriac, but born in a poorer family, my mind is all I have.

Thanks in advance.

Thank you for asking at Ehealth forum!

I read your question and I understand your concern.
Single shot of haloperidol doesn't cause these long term effects.I would suggest you to consult a psychiatrist to evaluate you as without evaluation diagnosis is tough.
I hope it helps. Stay in touch with your healthcare provider for further guidance as our answers are just for education and counselling purposes and cannot be an alternative to actual visit to a doctor.
Take care
