/activatemysavings.com/canasa/register.phpEnemas may help, but the canasa really works well for that last 1 inch. The enemas can miss that area. I used Canasa for a long time with good luck. Some of these copay cards don't work for people with medicare but give it a try. Otherwise, try the genric mesalamine enemas, or I've ordered generic Canasa from Canada, but it takes time to get here, and some people don't like ordering from another country.
