If you’ve ever wondered why the last little dose was the hardest to give up — harder than the big cuts earlier — this is the answer. It’s called hyperbolic tapering, and once you see it, the whole process makes sense.
The straight-line mistake
Most tapers are done in equal milligram steps — drop 10 mg, then another 10 mg, then another. It seems fair. But the brain doesn’t respond to dose in a straight line, so equal-sized cuts do not create equal-sized effects. The early cuts feel like nothing. The last ones feel enormous.
The curve, in plain English
The relationship between a dose and its effect on brain receptors is a curve, not a line. At higher doses the receptors are nearly “full,” so a big milligram cut barely changes the effect. At low doses, even a tiny cut removes a large share of the remaining effect. That’s why coming down from a small dose to zero can knock people flat — the final stretch is doing the heaviest lifting.
Equal milligram cuts aren’t equal. The curve is why the bottom of the taper is the hardest part.
The fix: shrink by percentage, not by milligrams
Hyperbolic tapering means reducing by a percentage of your current dose — often around 10% — rather than a fixed amount. As the dose gets smaller, so do the steps. Each reduction then feels about the same, the whole way down. The result is a taper that gets gentler exactly where the old way got brutal.
What that looks like in practice
- Reductions sized to your current dose, not a fixed pill fraction
- Holding each step a few weeks until you feel steady
- The smallest steps saved for the very end
- Often needing liquid medication or compounded micro-doses to make low doses possible
This approach is at the heart of The Maudsley Deprescribing Guidelines, and it applies to antidepressants (SSRIs and SNRIs) and, with extra care, to benzodiazepines too.
You don’t have to figure this out alone.
The people who come off most comfortably almost always have a Provider doing it with them — someone who knows the slow way.

When people “fail” at coming off a medication, the method usually failed them — not the other way around. Hyperbolic tapering is the difference between a cliff and a gentle ramp. The catch is that it requires doses smaller than standard tablets allow, which is where a Provider who does this comes in.
