When will haloperidol depot be out of my body?

So I was injecting haloperidol depot at various intervals, some weekly, 2 weeks, 3 weeeks and 4, weeks. The last time i was injected was almost 4 weeks ago, I read it that haloperidol depot half life is 3 weeks, but had a really low blood level drop later on. My question is when im not gonna have haloperidol depot in my system?

I guess it will take half a year befor that the Haldol is totally out of your bloodstream.

Are you quitting Haldol against medical advice?

No, I am making a switch with my pdoc

Found this, so basically I wont feel haloperidol effects after another 2 months

10% of your initial depot is about 3 halflifes.
I think with depot the halflife isn’t actually 3 weeks but much shorter, but I don’t have a resource.


Damn guys, probably gonna feel haloperidol in me for a long time…

Did you get a 100 mg shot?
You already made one month! 2 months to go.
I read somewhere that the haloperidol molecules block certain D2 receptors for up to a few months sometimes, I don’t know how true that is.
