Sucralfate 10% enema off-license treatment for radiation proctitis


Has anybody here been treated or know anyone who's been treated for radiation proctitis with Sucralfate 10% enema?  it's an off-license treatment.

I need to find out the "shelf life" for the Sucralfate 10% enemas.

Prostate cancer treatment was provided in the US; patient now living in the UK.
