- For children and adolescents, perform fecal occult blood testing before initiating treatment and after 1 year of treatment; colonoscopy/sigmoidoscopy required if there is unexplained blood in the stool
- See Dosing Considerations for recommendations
Drug interaction overview
- Based on the pharmacodynamic effect of teduglutide, absorption of concomitantly administered oral medications may be increased
- Monitor patients receiving concomitant oral drugs requiring titration or with a narrow therapeutic index for adverse reactions due to potential increased absorption of concomitant drug
- Concomitant drug may require dosage reduction
Pregnancy & Lactation
Pregnancy
Available data from case reports in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes; pregnant women with short bowel syndrome are at risk for malnutrition, which is associated with adverse maternal and fetal outcomes; severe malnutrition in pregnant women is associated with preterm delivery, low birth weight, intrauterine growth restriction, congenital malformations and perinatal mortality
Animal data
- In animal reproduction studies, no effects on embryo-fetal development were observed with subcutaneous administration to pregnant rats and rabbits during organogenesis at exposures up to 686 times the clinical exposure at recommended human dose
Lactation
There is no information regarding presence in human milk, effects on the breastfed infant, or on milk production; drug is present in milk of lactating rats; systemic exposure to a breastfed infant is expected to be low; however, because of the potential for serious adverse reactions in a breastfed infant, including tumorigenicity, advise patients that breastfeeding is not recommended during treatment
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Analog of naturally occurring glucagonlike peptide-2 (GLP-2); binds to the GLP-2R receptors located in intestinal subpopulations of enteroendocrine cells, subepithelial myofibroblasts, and enteric neurons of the submucosal and myenteric plexus
Activation of these receptors results in local release of intestinal mediators that increase intestinal absorptive capacity, resulting in increased fluid and nutrient absorption

- 128 mcg•hr/mL (children aged 1-11 yr)
Distribution
Vd: 103 mL/kg
Metabolism
Expected to be metabolized by hydrolytic degradation (like native BLP-2)
Elimination
Renal clearance: 123 mL/hr/kg (adults)
Excretion: Primarily in urine
Half-life
- 1.3 hr (SBS)
- ~2 hr (healthy volunteers)
- 1 hr (adolescents aged 12-17 yr)
- 0.7 hr (children aged 1-11 yr)

It works by helping to improve intestinal absorption of fluids and nutrients.
