Instructed patient If there is a small leak under my skin barrier, is it okay to patch it with tape or paste: Do not try to patch the pouching system with tape or paste. A leak under the skin barrier should not be fixed. Leaving a leaking pouch on can cause skin irritation. Always empty your pouch before it is half-full. Release gas before the pouch gets too full. If you have a lot of gas, you may want to consider using a pouch with a vent or filter.
