Oral contraceptives may trigger chorea, a neurological disorder, in women. Symptoms resolved after discontinuing the medication, suggesting a link between oral contraceptives and chorea development.

Area of Science:

  • Neurology
  • Endocrinology
  • Pharmacology

Background:

  • Oral contraceptives (OCs) are widely used for birth control and hormone replacement therapy.
  • Chorea is a movement disorder characterized by involuntary, irregular, and unpredictable muscle movements.

Observation:

  • Three cases of chorea developing in patients using oral contraceptives are presented.
  • Two patients developed chorea long after initiating oral contraceptive therapy; symptoms resolved upon discontinuation.
  • A third patient experienced amphetamine-induced chorea following prolonged oral contraceptive use.

Findings:

  • Prolonged administration of female sex hormones, as found in oral contraceptives, may precipitate chorea.
  • This suggests a potential etiological link between oral contraceptives and the development of chorea, even in the absence of prior history or rheumatic fever.

Implications:

  • Clinicians should consider oral contraceptives as a potential contributing factor in cases of new-onset chorea in women.
  • Further research is warranted to elucidate the precise mechanisms underlying hormone-induced chorea.
  • This finding may inform prescribing practices and patient counseling regarding oral contraceptives.
