Metamucil

Metamucil is an over-the-counter fiber supplement containing psyllium husk. It works by absorbing liquid in the intestines to form a bulky, soft stool, which stimulates bowel movement. It must be taken with at least 8 ounces of water or other liquid to prevent choking and intestinal blockage.

Dosage by Body Weight

For adults and children 12 years and older, the typical dose is 1 rounded teaspoon or 1 packet of powder mixed in 8 oz of liquid, 1 to 3 times daily. For children aged 6 to 11, use half the adult dose. Not recommended for children under 6 years of age without consulting a doctor.
