Frequently asked questions
How does sucralfate work?
It forms a protective coat over ulcers, shielding them from acid while they heal.
Can I take it with my other medicines?
Take other medicines a couple of hours apart from sucralfate, as it can block their absorption.
Why am I constipated?
Sucralfate contains aluminium, which commonly causes constipation. Drink water and eat fibre.
