About Gattex


GATTEX® is a prescription medicine used in adults and children 1 year of age and older with short bowel syndrome (SBS) who are dependent on parenteral support (PS)

GATTEX works like a natural GLP-2.

In a study of adults, GATTEX was proven to help the remaining intestine absorb more fluid.*


Increased the surface area of the villi in the intestines

Increased absorption of fluid by the intestines by ~750 to 1000 mL/day

The ability of GATTEX to improve the amount of fluid absorbed by the intestines was studied in 17 adults with SBS. Participants in the study received GATTEX for 21 days. All the participants in this study knew they were taking GATTEX. They each took daily doses of either 0.03, 0.10, or 0.15 mg/kg by injection (0.6 to 3 times the recommended dose). The injections were administered under the skin in the stomach area (abdomen). All of the doses studied, except for the 0.03 mg/kg once-daily dose, resulted in enhanced absorption of fluid by the intestines—approximately 750 to 1000 mL per day—and increased the surface area of the intestines.

The ability of GATTEX to improve intestinal absorption in children has not been investigated.

Gattex is the first and only medicine that works like the glp-2 the body normally makes on its own

Common Side Effects of GATTEX

In clinical studies of adults, the most common (≥10%) side effects were:

Stomach area (abdomen) pain or swelling



Swelling of the hands or feet

Cold or flu symptoms

Allergic reactions

Skin reaction where the injection was given

The safety of GATTEX has been studied in 41 children with SBS across 2 clinical studies*

The side effects seen in children and adolescents (aged 1 to 17 years) were similar to those seen in adults. Be sure to talk to your or your child’s doctor about any side effects that are bothersome or that do not go away.

This includes pediatric patients from an additional 3-month study that was conducted with GATTEX.

Gattex has been approved for use in children since 2019 And has been prescribed for adults with sbs since 2012
