Can someone tell me how long it takes Cisapride to work in an older cat?

Question

My cat foams a little in the mouth when I give it to him. Is that the medicine working? Today is his second day on it and I haven't seen any change in his constipation. Thanks in advance!

Answer 1

The med usually takes about 2-3 days at least to notice  change. He may be foaming because of the taste.  I offer a half teaspoon of wet cat food immediately after dosing, and my cat completely forget what just happened. If you have been prescribed Cisapride, you may always have to keep an eye out for bowel changes - my guy has been on this med off and on for 8 years.  The last time he went off for 2 months, and his intestines swelled up and were painful.  Now he also gets  a sprinkle of unflavored Metamucil in a spoonful of wet food every day  - just to help keep things moving.  If he hasn't had a bowel movement in the next 24 hours, the vet may have to give an e***a - a very unpleasant situation for both of you . . .
