Hyperbolic Tapering: Why Linear Dose Reductions Fail Patients
Most taper protocols still use linear reductions — cutting the same absolute amount at each step. Drop from 40mg to 30mg, then 20mg, then 10mg, then stop. It seems logical, but the pharmacology tells a different story.
Serotonin receptor occupancy follows a hyperbolic curve. At higher doses, large reductions produce relatively small changes in receptor occupancy. But at lower doses, the same absolute reduction causes massive shifts — which is exactly when withdrawal symptoms hit hardest.
Why This Matters
- • A 50% dose cut at 40mg changes receptor occupancy by ~5%. The same cut at 5mg changes it by ~40%.
- • Hyperbolic tapering makes smaller cuts at lower doses to keep the receptor impact consistent
- • Patients experience smoother transitions with fewer severe withdrawal episodes
- • This is the foundation of the Maudsley Deprescribing Guidelines approach
