What is Vraylar’s (cariprazine) half-life?
Vraylar (cariprazine) has a long elimination half-life because it slowly clears from the body and forms active metabolites. Reported half-life values are about 2 to 4 days for the parent drug and about 1 to 3 weeks for its active metabolites. [1]
Why does Vraylar take so long to clear?
Cariprazine is metabolized into active compounds that remain in the body for weeks. This is why the “effective” half-life clinicians talk about is much longer than the parent drug’s half-life. [1]
How long until it leaves the body?
A precise timeline depends on dose, kidney/liver function, age, other medications, and how you define “leaves” (e.g., half vs. near-complete elimination). With a parent half-life of 2–4 days and active metabolite half-life of 1–3 weeks, it can take several weeks for levels to substantially drop. [1]
How does half-life affect missed doses or stopping Vraylar?
Because both cariprazine and its active metabolites persist, missing a dose typically does not lead to immediate loss of effect, and stopping does not produce an immediate “washout.” Levels can remain for weeks after discontinuation. [1]
If you need the exact numbers for your prescription label
Half-life figures are typically presented in the drug’s prescribing information and can vary slightly by source or study method. Checking the latest U.S. label (or your local equivalent) will give the most current and precise values. [1]
