What is Congenital Sucrase-Isomaltase Deficiency?
CSID is a disorder that reduces the effectiveness of enzymes that digest carbohydrates (sugar and starch). Congenital Sucrase-Isomaltase Deficiency, also known as Genetic Sucrase-Isomaltase Deficiency (GSID), is an inherited disorder that causes these digestive enzymes either to be missing or to not work as well.

What is Sucraid?
Sucraid is an FDA-approved drug for the treatment of genetically determined sucrase deficiency, which is part of Congenital Sucrase-Isomaltase Deficiency (CSID). Sucraid is an enzyme replacement therapy, providing a substitute for the sucrase enzyme in the small intestine that is missing or not working in people who have CSID. CSID may also be called Sucrose Intolerance, carbohydrate maldigestion or intolerance or Genetic Sucrase-Isomaltase Deficiency (GSID).
Sucraid is a drug that is only available by prescription, but a prescription for Sucraid cannot be filled by your corner drugstore. The only way to get a Sucraid prescription filled is through the specialty pharmacy, US Bioservices 1-833-800-0122.
If your doctor has prescribed Sucraid for you, it is either because you have been diagnosed with a sucrase-isomaltase enzyme deficiency or because your doctor suspects the reason why you have frequent GI symptoms is because the sucrase-isomaltase enzymes in your small intestine are not working. If that is the case, your doctor wishes to determine if a trial of Sucraid therapy would help relieve some of your GI symptoms.
