Half-life
~48-96 hours for cariprazine; ~1-3 weeks for active metabolite (one of the longest of any psychiatric medication).
Withdrawal timeline
Very gradual onset due to extremely long metabolite half-life.
Return of underlying symptoms typically emerges over a 1-3 month window.
Depends on alternative treatment.
Common symptoms
- Return of underlying condition
- Anxiety
Less common
- Sleep disturbance
Tapering guidance
- A typical taper reduces by 1.5 mg every 2-4 weeks. The long half-life provides a built-in auto-taper.
- Coordinate the taper with the prescribing psychiatrist.
Where ketamine therapy fits
Vraylar is compatible with at-home ketamine therapy. Continue Vraylar as prescribed during ketamine treatment unless the prescribing psychiatrist advises otherwise.
Frequently asked questions
Why is Vraylar withdrawal more gradual than other antipsychotics?
The active metabolite has a half-life of 1-3 weeks, far longer than any other antipsychotic. This produces a built-in auto-taper after the last dose.
