How to take GATTEX

Once trained by a healthcare provider, adults can self-administer. For children, GATTEX must be administered by an adult. Self-administration is not recommended in pediatric patients.

Using GATTEX

  • Use GATTEX exactly as your healthcare provider tells you to

  • If you use more than 1 dose, call your healthcare provider right away
