Summary
Oral contraceptives rarely cause chorea, a movement disorder. Discontinuing the medication led to significant improvement and full recovery of choreic movements in a young woman.
Area of Science:
- Neurology
- Endocrinology
Background:
- Oral contraceptives containing ethinyl-estradiol and norethisterone are widely prescribed.
- Movement disorders are rare but potential adverse effects of hormonal therapies.
Observation:
- A 26-year-old woman developed left-sided hemichorea while using oral contraceptives.
- The choreic movements were involuntary and significantly impacted her daily activities.
Findings:
- Discontinuation of the oral contraceptive resulted in a marked improvement in choreic movements.
- Complete resolution of the hemichorea was observed within six weeks of stopping the medication.
Implications:
- This case highlights a rare complication of oral contraceptive use.
- Understanding the mechanisms of drug-induced chorea is important for clinical management and patient counseling.
