lurasidone-hydrochloride and Edema

Lurasidone, an atypical antipsychotic, is currently approved for treatment of schizophrenia and bipolar depression. Little is known about whether lurasidone might also cause pedal edema. A 55-year-old female patient had been diagnosed with bipolar I disorder from the age of 26. She had been prescribed escitalopram and quetiapine 300 mg/day for her persistent depressive mood. Later, she took lurasidone plus escitalopram to treat depressive episode. Consequently, she developed mild bilateral swelling over the lower legs and ankles. After lurasidone was discontinued, the bilateral pedal edema was completely resolved, and no further recurrence of edema occurred. Resolution of the edema after discontinuation of lurasidone indicates that the edema may have been caused by lurasidone. Caution should be needed when prescribing lurasidone for patients, as pedal edema may affect patients' adherence to the prescription.
