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).

US Bioservices

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.

Trial Therapy

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.

Here’s What You Get
  • Sucraid comes in a translucent plastic bottle containing approximately 118 mL of concentrated solution, packaged with two bottles per box
  • Each mL of solution contains 8,500 international units (IU) of sacrosidase
  • A 1-mL measuring scoop is provided with each box
Patient Stories

For us, Sucraid is the difference between strict diet adherence and a more normal diet. Sucraid means more freedom of choice for us.

Aileen, Caregiver for Patient Treated With Sucraid


An enzyme is a naturally-occurring protein that makes the chemical reactions that occur all the time in the body, occur much faster.

We rely on the enzymes our body produces to help the tissues and organs in our body function normally. Sucrase is the enzyme that helps our body digest sucrose, which is a fancy name for white table sugar.

Enzyme - A Naturally-Occurring Protein

Sucrose is a complex sugar called a disaccharide, created by the combination of two simple sugars (saccharides), glucose and fructose.

Sucrose is mainly found in plants and is the primary component of most granulated sugars we use in baking. It’s commonly known as white table sugar and/or brown sugar, or just sugar. These sugars are mostly refined from sugar beets or sugar cane. Today, sucrose can be found in a range of commercially prepared foods like cookies, ice cream, candy, crackers, and cured meats. Sucrose is also found naturally in many fresh fruits.

Sucraid facilitates the breakdown of the complex sugar (sucrose) into its simpler forms, enabling the absorption of the simple sugars from the small intestine into the bloodstream where it can be used by the tissues and organs in the body as a source of energy. In clinical studies of CSID patients, sacrosidase, the active ingredient in Sucraid, was shown to provide significant relief for most patients of the gastrointestinal (GI) symptoms associated with CSID. Sucraid can help affected individuals maintain a more normal diet that can include foods that contain sucrose.

Scientific words sometimes use the same ending to identify various compounds that all belong to the same, specific category.

For example, the names for various sugars all end in “ose,” such as glucose, fructose, lactose, and sucrose. The names for various enzymes often begin with the name for the compound they affect and all end in “ase,” such as lactase, which breaks down lactose; protease, which breaks down proteins; lipase, which breaks down lipids (fats); and sucrase, which breaks down sucrose.

Insights to Sucraid

Carbohydrates are one of the three main sources of nutrients in our diets.

The other two are proteins and lipids (fats). Carbohydrates are made by plants to store energy. They are complex compounds that must be broken down to a simpler form before they can be absorbed into the bloodstream.

There are three types of carbohydrates. Sugars are simple or complex carbohydrates, found in white table sugar, baked goods, fruits, vegetables, and dairy products. Starches are made up of more than one sugar unit bound together and are found in whole grains, potatoes, pasta, vegetables, and beans. Dietary fiber is a very complex carbohydrate that your body cannot digest, so it passes through the intestine undigested. Fiber is a food source for the “good” bacteria that exist naturally in your large intestine. Fiber is present in fruits, vegetables, legumes, nuts, seeds, and whole grains.

If you think you may have CSID, it is recommended that you schedule a visit to discuss your concerns with a gastroenterologist.

Important Safety Information for Sucraid® (sacrosidase) Oral Solution

  • Sucraid® may cause a serious allergic reaction. If you notice any swelling or have difficulty breathing, get emergency help right away.
  • Sucraid® does not break down some sugars that come from the digestion of starch. You may need to restrict the amount of starch in your diet. Your doctor will tell you if you should restrict starch in your diet.
  • Tell your doctor if you are allergic to, have ever had a reaction to, or have ever had difficulty taking yeast, yeast products, papain, or glycerin (glycerol).
  • Tell your doctor if you have diabetes, as your blood glucose levels may change if you begin taking Sucraid®. Your doctor will tell you if your diet or diabetes medicines need to be changed.

  • Sucraid® has not been tested to see if it works in patients with secondary (acquired) sucrase deficiency.
  • NEVER HEAT SUCRAID® OR PUT IT IN WARM OR HOT BEVERAGES OR INFANT FORMULA. Do not mix Sucraid® with fruit juice or take it with fruit juice. Take Sucraid® as prescribed by your doctor. Normally, half the dose of Sucraid® is taken before a meal or snack and the other half is taken during the meal or snack.
