Deprescribing — stopping medications that are no longer serving the patient — is clinical work that deserves the same care as starting medications. Done well, it reduces side effect burden, simplifies regimens, and often improves function. Done poorly, it triggers withdrawal, missed symptoms, or premature discontinuation that undoes the original treatment.
Identify candidates for deprescribing at every visit with patients on long-term medication. The benzodiazepine that was started for acute anxiety three years ago and continues from inertia. The antipsychotic added during a hospitalization that may no longer be needed. The PRN sleep aid that's now nightly. The combination that's accumulated without anyone systematically reviewing whether each component is still earning its place. Periodic medication review identifying deprescribing candidates is part of good care.
Discuss with the patient. Don't deprescribe without explaining. "You've been on this for three years; let's think about whether we still need it." Patients often have feelings about deprescribing — fear that symptoms will return, attachment to the medication as security, sometimes relief that you're suggesting it. Address the feelings as you plan the taper.
Taper slowly, calibrated to the drug. Benzodiazepines often require taper over months. SSRIs over weeks. Antipsychotics often over weeks to months. The faster the taper, the more likely the patient will experience withdrawal symptoms that they (and you) may misinterpret as recurrence of the original condition. Slow tapers tolerate better and produce cleaner clinical pictures.
Distinguish withdrawal from relapse. Withdrawal typically emerges quickly (days), follows a stereotyped pattern related to the drug's pharmacology, and resolves with re-dosing or completion of the withdrawal window. Relapse takes longer to emerge (weeks), looks like the original condition, and doesn't resolve with brief re-dosing. The patient who has flu-like symptoms and dizziness within 48 hours of stopping venlafaxine is in withdrawal; the patient whose depression returns four weeks after stopping is in relapse.
Reassess at intervals. Deprescribing isn't always successful; sometimes symptoms re-emerge and the medication should be restarted. That's a clinical outcome, not a failure. Resume what was working; document the trial.
