Metoclopramide in vincristine-induced ileus.

Three cases of vincristine-induced gastrointestinal toxicity were treated with metoclopramide. Two patients had severe abdominal pain and adynamic ileus, while the third had severe constipation and abdominal bloating. Rapid resolution of symptoms occurred in all three patients. Metoclopramide may, therefore, prove useful in the treatment of these not infrequent toxic effects of vinca alkaloids.
