My advice is don't take any caree home until help sorted eg continence nurse etc. OT can order pads in hospital too. Nhs supplies limited amount and extras need to be purchased from AA. They are expensive.
From my experience IV antibiotics cause faeces to run from the caree but it gets better when they are back on tablets. Eventually returning to what it was like before normal/constipated etc. wish you well and for a good recovery for caree.
