She was asked to refill a prescription for a drug called domperidone to help a patient with lactation. Domperidone is not FDA approved in the United States for any indication. However, in Europe and in Canada it is approved as a promotility agent for patients with a condition called gastroparesis, which causes the stomach to empty very slowly and results in chronic nausea and vomiting. As a side effect the drug is also known to increase the production of prolactin, a hormone that stimulates milk production. In the case of this physician’s patient, she had adopted a child and found that the medication had effectively enabled her to produce milk and nurse, with seemingly no untoward effects. It’s unclear who had initially prescribed the drug, but various online lactation support forums discuss it as an option for women who have trouble with lactation.
The questions: Is it legal, ethical or good medical practice for a physician in the United States to write a prescription for domperidone for a patient who has been using it for lactation with good results? How about for gastroparesis? Where does one get the drug? Is it even legal to sell the drug in the United States?
I’ve cared for at least two patients who have used domperidone. In both instances it was ordered by prescription from an overseas source by a local gastroenterologist. In these two cases my patients had tried just about everything on the market in the United States for gastroparesis and were still struggling with debilitating symptoms. In one case, my patient had required hospitalizations and ultimately a feeding tube because of intractable vomiting. The drug was ineffective in both patients and it was eventually discontinued.
