Does Imodium Effectively Treat Diarrhea?

Question : I have crohns , my ulcers are healed and I am in remission according to my doctor. I take shots once a month , it is called Cizmia. I was also on cortisteroids. My doctor told me to quit taking the cortisteroid and when I did the dirrehea came back with a vengence. It is watery stool and sometimes several, several times a day. Usually over 10 times a day I will go. I had a colon scan and a barium scan. Both were negative for ulcers. If I take the cortisteroid my dirrehea goes away. But, the cortisteroid gives other problems. Such as weight gain, hair loss, my arms if I bump them will immediately have a red spot appear like a blood blister. My face swells and becomes red on the cheeks. i cannot have any meds. with sulfa in them, so that limits my options. I just had a blood test and a stool sample taken. I don't have the results yet.. what do you suggest . Is there a different treatment that I can use? Sorry about the spelling.

My doctor has asked to have my shots upped to twice a month, the insurance will not pay for twice a month. My body is not retaining enough of the shot from one month to the next time.

I tried Imodium for 2 days, then I stopped as it seemed not to help, I guess I was taking it in a high enough doses as it said on the bottle not exceed 30 mg in 24 hours. I will try this again, please send me a dose schedule so I will get the right benefit, thanks
