How Manevac Granules work

Manevac Granules contain ispaghula seed and ispaghula husk. Both of these are bulk-forming laxatives.

The granules also contain tinnevelly senna pods which are a stimulant laxative.

Before taking this product, sit in an upright position. Place the granules on the tongue and swallow with plenty of water. Do not crush or chew the granules. 

You should drink 5-10 glasses of fluid each day whilst you are taking the granules.
