Flecainide, a medication, can cause drug-induced movement disorders, including involuntary biting and grimacing. This case suggests flecainide should be recognized for its potential to induce such adverse effects.

Area of Science:

  • Pharmacology
  • Neurology
  • Clinical Medicine

Background:

  • Flecainide is an antiarrhythmic medication.
  • Drug-induced movement disorders are a known class of adverse drug reactions.

Observation:

  • A 55-year-old male patient experienced new-onset orofacial symptoms.
  • Symptoms included teeth clicking, involuntary biting, chewing, and grimacing.

Findings:

  • The onset of symptoms was rapid, occurring within three days of starting flecainide.
  • These symptoms are consistent with drug-induced movement disorders.

Implications:

  • Flecainide may be associated with drug-induced movement disorders.
  • This finding expands the list of medications linked to movement disorders.
