Severe Restless Legs Syndrome in a Pregnant Woman Leading to Induced Premature Birth

Restless legs syndrome (RLS) often develops or is commonly aggravated during pregnancy in women. Due to potential teratogenic risk of the medication for RLS, non-pharmacologic management is commonly tried during pregnancy instead of medication. We report a 30-year-old pregnant woman who intentionally delivered a baby at 32 weeks 5 days to take medication due to severe RLS and insomnia. Depending on gestational period, more active treatments should be considered to prevent serious adverse pregnancy outcome for pregnant women with severe RLS.
