Can Austedo Be Stopped Abruptly Without Tapering?
Yes, Austedo (deutetrabenazine) can be discontinued abruptly without tapering according to the FDA-approved prescribing information. 1
FDA-Approved Discontinuation Protocol
The official FDA label for Austedo explicitly states: "Treatment with AUSTEDO XR or AUSTEDO can be discontinued without tapering." 1 This is a clear, unambiguous directive from the drug manufacturer based on regulatory approval data.
Key Discontinuation Guidelines:
- No tapering required when stopping the medication
- Treatment interruption > 1 week: Requires re-titration when restarting
- Treatment interruption < 1 week: Can resume at previous maintenance dose without titration 1
Clinical Evidence Supporting Abrupt Discontinuation
Long-term safety data from the ARC-HD open-label extension study (119 patients, up to 145 weeks of treatment) demonstrated that "there were no unexpected adverse events upon drug withdrawal" when deutetrabenazine was stopped. 2
What Happens When You Stop:
- Chorea symptoms return: Mean total maximal chorea scores increased 4.7 units from week 8 to 1-week follow-up after discontinuation 2
- No withdrawal syndrome: Unlike benzodiazepines, SSRIs, or antipsychotics, deutetrabenazine does not produce a withdrawal syndrome requiring gradual tapering
- Return of underlying symptoms: The worsening represents return of the underlying movement disorder, not a rebound phenomenon
Important Clinical Distinctions
This differs markedly from other psychotropic medications:
- Antipsychotics for tics: Guidelines recommend gradual tapering to avoid rebound worsening 3
- Benzodiazepines: Require gradual tapering (25% dose reduction every 1-2 weeks) to avoid withdrawal symptoms including seizures 4, 5
- Antidepressants: Should be tapered to minimize withdrawal symptoms 6, 7
Practical Management
When stopping Austedo:
- Discontinue at current dose without tapering
- Monitor for return of chorea or tardive dyskinesia symptoms
- If restarting after > 1 week off, begin re-titration from 12 mg/day (AUSTEDO XR) or 6 mg twice daily (AUSTEDO) 1
- If restarting within 1 week, resume previous maintenance dose
Common pitfall to avoid: Do not confuse the return of underlying movement disorder symptoms with a withdrawal syndrome requiring tapering. The increase in chorea after stopping represents the natural course of untreated disease, not drug withdrawal.
