What I want to ask, is the Lactulose potentially causing her stomach to be upset? I was told both times I went to the Vet that Lactulose shouldn't be causing something like this and at worst would only cause diarrhea but it'd be great if others could share their personal experiences with potentially similar situations to mine. I was given Lactulose twice a day to syringe down her throat which called several rhinitis which is a sinus condition so I stopped the lactulose which was not very effective and switched her to Miralax2x per day fluctuating from 1/4 to a 1/2 teaspoon a day depending on the severity of the constipation.

Understanding the Context

Artie was on many medications: Cisapride, Lactulose, Miralax, and daily sub-q fluids; along with many enemas. I ended up using an extra calendar, to track stools; correlating it with amount of meds given. Lactulose is effective is the pet is properly hydrated, because it works by recalling fluids from the system. If the issue is chronic, I would use something less irritant.

Key Insights

In my case, I used psyllium seeds added to the wet food every day. It worked. Hi, my Siamese was started on lactulose with cisapride 2 months ago after fiber diet and reg. lactulose failed to work over time,so any other cat owners have any experience with lactulose with cisapride? I know that for humans cisapride was d/c due to arrhythmias.

Final Thoughts

Please any feed back would be... We treated her with lactulose for a few months and then the lactulose stopped working. This vet sent me to a holistic vet that immediately wanted me to discontinue the lactulose and start my cat on PEG 3350 (Miralax). She said that the difference she sees in her patients who use Miralax is amazing. Been giving my cat lactulose for his megacolon for a while now. He's doing good.

But I have a few small trips this year where he will be left alone, with surveillance and an emergency contact, for maximum of two days. Usually I would put out enough food and water and keep an eye on him while I'm... Lactulose is essentially a man-made sugar that the cat cannot digest well so, long story short, it is supposed to boost the moisture level in poo and hopefully aid the cat in pooping better.
