This medication is used for long-term treatment in people with a certain inherited disease (Fabry disease). In Fabry disease, a certain enzyme in your body (alpha-galactosidase) does not work the way it should. This leads to a buildup of a certain fatty substance in your kidneys, heart, and other organs. Migalastat works by helping alpha-galactosidase work better so it can remove the fatty substance. Treatment can decrease some symptoms caused by Fabry disease, such as abdominal cramps, diarrhea, burning pain in the hands and feet, heat intolerance, skin rash, kidney/heart disease, or stroke.
