Brava® Lubricating Deodorant can be used to mask odor when changing your pouch and due to the lubricating effect, it also makes emptying easier if you're using a drainable pouch.
Add 6-10 drops into the pouch when changing and emptying it and distribute it evenly by rubbing the inner sides of the pouch together (avoiding the filter). This will help the output/stool glide into the pouch more easily, ensuring that the output is always at the bottom of the pouch and not around your stoma.
