If your symptoms are one solid bm daily and with a bit of blood, I'd say your flare is rectally only and that's a good thing your doc put you on the rectal meds.
When did you start them?
Do you use the enemas at night or during the day?
I would call the doc and ask if you could try the Rowasa (or Salofalk if you're not in the US) instead of the cortenema if you think they're not working for you.
The other option would be to add 5ASA suppositores to the regimen you're on at this time.
*Heather* Status..Asacol 6 (3 twice daily); enemas every 4th night
~diagnosed January 1989 UC (proctosigmoiditis)
~Bentylol (dicyclomine) 20mg as needed
~Probiotics....(Natural Factors Protec 2 or 3 + 1 or 2 Primadophilus Reuteri Pearls @ bedtime
~multi-digestive enzymes as needed
~Ranitidine,Pariet (reflux); Effexor XR 75mg(depression); Pulmicort/Airomir (asthma)
~URSO for PSC (or PBC) 500mg X 2 daily (LFTs back to NORMAL!!)
My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
