What is this medication?

PSYLLIUM (SIL i yum) may support digestion and heart health. It works by increasing the bulk of your stool. This increases pressure, which helps the muscles in your intestine move stool. It also reduces the amount of cholesterol your body absorbs from food.

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.
