Synthetic form of sucrase; derived from Saccharomyces cerevisiae.

Uses for Sacrosidase

Congenital Sucrase-Isomaltase Deficiency

Oral replacement therapy for the genetic sucrase deficiency that is part of congenital sucrase-isomaltase deficiency (CSID) (designated an orphan drug by FDA for this use).

May be used as a short (e.g., 1-week) therapeutic trial to assess response in patients suspected of having CSID when the diagnosis is in doubt.

Sacrosidase Dosage and Administration


Oral Administration

Administer orally with each meal or snack.

Use measuring scoop or dropper dispensing tip provided by manufacturer for measurement of the dose.

Dose must be diluted with 60–120 mL of water, milk, or infant formula prior to administration. Do not dilute or consume with fruit juice. (See Compatibility under Stability.)

Do not warm or heat diluents before or after addition of sacrosidase; decreased potency likely with heat. Administer cold or at room temperature.

Administration with food and/or milk appears to diminish the degradation of the enzyme by intragastric pepsin. (See Elimination under Pharmacokinetics.)

Administer half of each dose at the beginning of each meal or snack, and the other half at the end of meal or snack.


Dosage expressed in international units (IU, units). Each mL of sacrosidase contains 8500 units of the enzyme.

Pediatric Patients

Congenital Sucrase-Isomaltase Deficiency

For patients weighing ≤15 kg: 8500 units (1 mL using the measuring scoop provided or 22 drops from the Sucraid container tip) with each meal or snack.

For patients weighing >15 kg: 17,000 units (2 mL using the measuring scoop provided or 44 drops from the Sucraid container tip) with each meal or snack.


Congenital Sucrase-Isomaltase Deficiency

17,000 units (2 mL using the measuring scoop provided or 44 drops from the Sucraid container tip) with each meal or snack.

Special Populations

No special population dosage recommendations at this time.

Cautions for Sacrosidase



Sensitivity Reactions

Hypersensitivity Reactions

Serious hypersensitivity reactions (i.e., severe wheezing) reported 90 minutes after administration of a second dose.

Administer initial doses near a facility where adequate treatment for acute hypersensitivity reactions can be obtained. Alternatively, perform skin testing to assess presence of hypersensitivity to sacrosidase.

If hypersensitivity reaction occurs, discontinue immediately and institute appropriate therapy as indicated (e.g., epinephrine, corticosteroids, maintenance of an adequate airway, oxygen).

General Precautions

Dietary Restriction of Starch

Sacrosidase does not provide replacement for isomaltase deficiency; restriction of dietary starch may be necessary to achieve greatest reduction in symptoms. Evaluate each patient treated to determine need for restriction of dietary starch.

Acquired Disaccharidase Deficiencies

Not evaluated in patients with secondary (acquired) disaccharidase deficiencies.

Diabetes Mellitus

Sacrosidase allows absorption of glucose and fructose (products of sucrose hydrolysis); careful consideration recommended in dietary planning in patients with diabetes mellitus.

Specific Populations


Category C.


Not distributed into milk; sacrosidase not absorbed intact into systemic circulation.

Pediatric Use

Safety and efficacy established in pediatric patients; sacrosidase has been used in patients ≥5 months of age.

Common Adverse Effects

Abdominal pain, vomiting, constipation, diarrhea, nausea, dehydration, headache, insomnia, nervousness.

Sacrosidase Pharmacokinetics



Not absorbed intact into systemic circulation.



Undergoes degradation to simple amino acids by pepsin produced by the GI mucosa; resultant amino acids and peptides are absorbed into systemic circulation as nutrients.




Solution Concentrate

2–8°C; protect from heat and light. Discard 4 weeks after opening.



Solution Compatibility

May be diluted with water, milk, or infant formula.

Do not dilute or consume with fruit juice; acidity may reduce enzyme activity.


Advice to Patients


Excipients in commercially available drug preparations may have clinically important effects in some individuals; consult specific product labeling for details.

Please refer to the ASHP Drug Shortages Resource Center for information on shortages of one or more of these preparations.
