Metamucil Smooth is indicated for the relief of occasional constipation (bowel irregularity). 

As a bulk-forming laxative, Metamucil Smooth promotes intestinal movement by adding volume to the stool. Furthermore, it increases water content in the stool, making it softer and more easily passable. 

Uses and Dosage 

Carefully read and adhere to the instructions provided on Metamucil Smooth packaging before initial use and with each refill. For any inquiries or additional information, consult your healthcare provider or pharmacist. 

Metamucil Smooth is a powdered medication intended to be mixed with water and taken orally once to three times daily.
