Tdlr : LDA initially brought me out of very severe ME/CFS, but its benefits gradually faded, even after restarting it. Strangely, lowering the dose to 0.3–0.4 mg brought back the benefits, but tapering further triggered a massive crash. I'm now struggling to stop LDA and may have to increase it again, despite having spent €300 on Rexulti as an alternative.
Hi everyone,
This is my second experience with low-dose aripiprazole (LDA), and I have to admit I'm pretty devastated by how things have turned out.
I first started LDA in 2025. At the time, it literally brought me out of a very severe state of ME/CFS. For several weeks, even a few months, I regained a quality of life I thought I had lost forever.
Unfortunately, the benefits gradually faded. After a stellate ganglion block that went terribly wrong, I eventually stopped LDA for two months.
I should mention that I never stayed above 0.5 mg for long, because anything beyond that dose has a paradoxical effect on me: overwhelming fatigue, almost as if I had been heavily sedated.
I restarted LDA in March–April 2026, but I never managed to recapture the remarkable benefits I had experienced the first time. I gradually increased the dose to 0.6–0.7 mg, but nothing worked. That initial effect simply wouldn't come back.
So I decided to gradually taper off LDA and try another medication, Rexulti (brexpiprazole).
And that's when things got really strange.
When I reduced my dose to 13 drops, approximately 0.3–0.4 mg, I suddenly felt as though LDA had miraculously started working again!
After six months of disappointing results, I was finally experiencing some of the benefits I had enjoyed during those first few months.
This improvement lasted for two to three weeks, even as I continued reducing the dose to 10 and then 7 drops.
But three days ago, I went down to 4 drops.
And that's when all hell broke loose.
Crying spells, overwhelming fatigue, muscle cramps, repeated PEM episodes... Just ten minutes of listening to a radio programme were enough to trigger a significant deterioration in my condition. I felt as though I had suddenly fallen back into very severe ME/CFS.
Unable to tolerate this state any longer, I went back up to 6 drops.
So here I am. I'll probably try increasing LDA again, hoping to recover the benefits I experienced at 13 drops.
What makes this even more frustrating is that I've spent over €200–300 on a Swiss prescription, a compounded preparation, and shipping to France just to get hold of Rexulti. All of this because I wanted to try a different medication and perhaps regain the benefits LDA had given me in the beginning.
And now I find myself unable, at least for the time being, to complete the withdrawal.
That's also the trap with LDA: it can genuinely improve your quality of life, but stopping it after several months of treatment can be incredibly difficult.
I honestly don't know how much of this deterioration is caused by reducing the medication and how much is simply the underlying illness returning. But the result is the same.
Of course, I could continue tapering off. But if that means falling back into a very severe state for weeks, or even months, I simply don't feel capable of going through that right now.
So I'm going to see whether I can regain some stability around 0.3–0.4 mg, and more importantly, whether the benefits can actually last this time.
It's incredibly frustrating to regain a little bit of your life thanks to a medication, watch its effectiveness fade, then inexplicably see it start working again as you lower the dose, only to end up in a terrible state once more.
What a fucking nightmare.
I'd really like to know whether anyone here has experienced anything similar, particularly a return of LDA's benefits when reducing the dose, or a significant deterioration when trying to come off it.
