Description

Lactulose is a liquid medication prescribed to soften stools and manage the uncomfortable symptoms of constipation. It can also be used to help support animals who suffer from liver problems. Because it comes in a liquid form, it's easy to administer—simply add it to regular meals or give directly. Customers may receive this drug under the names Enulose, Cephulac, Kristalose.

Uses

Lactulose is used as a stool softener to help treat constipation. It has also been used in the treatment of liver disease to help prevent ammonia from building up in the blood.

Possible Side Effects

Diarrhea, loss of appetite, flatulence (increased gas), and cramping have been reported. Gastrointestinal side effects can subside with time. Other side effects may occur. An allergic reaction to Lactulose is possible. Your pet may experience swelling, listlessness, and shock if this occurs. If your pet appears sick in any way after receiving Lactulose, contact your veterinarian immediately. Let your veterinarian know if your pet produces less than 2-3 soft stools per day.

Drug & Food Interactions

Let your veterinarian know about any other medications or supplements your pet is taking before starting Lactulose. Some antibiotics, oral antacids, and other laxatives may interact with Lactulose. Other drug interactions are possible.

Precautions

This medication should not be used in pets who are hypersensitive to Lactulose. Lactulose may also alter insulin requirements in diabetic pets.

This drug is FDA-approved for human use. However, it is common practice for veterinarians to prescribe such drugs for use in dogs and cats.

    just ok, works best with Miralax

    By katwomanSF on Feb 15, 2021

    My 14.5 yo NFC boy is on this for life. I’m not sure when his problem started because my cats like to use the same litter box so when the other older than him passed, I suddenly noticed he was not having bowel movements. At first I thought it was lack of appetite and eating because he was severely depressed over Patches dying. He has had to go to the vet for enemas several times. So he is on this and cisapride to help with the contractions to BM’s and even then it’s about every 3 to 5 days sometimes. I’ve had to up his medicine a lot and I do notice if I add MiraLAX it seems to almost work better than this prescription, Or at least the combination. So I rate it as just OK.

    Constipation Relief

    By Teddy on Apr 10, 2021

    My kitty suffers from chronic constipation and this solution is the best for his problem. Keeps him healthy and happy! We use a baby syringe (or get one from the veterinarian) and it works great!

    Works very well!

    By Linda on Aug 6, 2020

    My boy will have to take this apparently forever for a mega colon issue. Am so thrilled he will take it in his food. Originally I was measuring in a syringe which was a mess getting the right amount, then pulling apart the syringe, washing it all... and the syringes don't last. Tested how many drops it would take to get the required dosage by measuring the cc's vs drops in teaspoon. Now instead of all that syringe agony I just use the original dropper type bottle from the vet and put the correct number of drops right into the food. No mess and no trouble seeing how much through the dark bottle. Hope this helps!

    Great Product

    By Mikey on Aug 8, 2020

    Our cat Zoey was diagnosed with mega colon and our vet put her on 2 ML twice a day for life. I fill a tiny Rubbermaid container and fill the syringe from that. Giving Zoey a syringe twice a day didn't go well. I put it on her soft food twice a day. She loves it. We love our pets!

    Never worked and cats hate it

    By Ouimcm on Aug 5, 2020 top500Contributor

    I paid $80 at vet for this and my cat still had 2 surgeries for blocked colon. Benefiber or mirilax works better. I had this from vet for 3 cats past few years, it never worked.

    You can use a tiny spoon to dispense this stuff

    By Donna on Jan 7, 2020

    I give my cats 1 or 2 doses per day and they don't get constipated - it's excellent. Instead of fiddling with a dropper, use a tiny baby spoon (smaller than a teaspoon). Measure 1 ML dose into the spoon, which will fill one tiny spoon. A spoon is easier to clean, just pour slowly from the bottle, then wipe the bottle so it doesn't get sticky.

    Such a price difference

    By Laura on Sep 27, 2019 top50Contributor

    This really helps my older guy and is tons cheaper on Chewy. Only thing that would make it better would be to change the top to allow for syringe. Otherwise the syringe gets all sticky and can get on the cats fur which is a mess

    Great solution for regular subscription

    By AngieinMI on Mar 10, 2019

    My cat will require daily lactulose for life. Getting her on a mail order prescription is a great time saver for me. One gripe about this brand is that it does not have a stopper or guide (not sure what it's called) for use with a needless syringe, so you have to dip the syringe into a dark bottle to get the medicine. Creates mess and possible contamination.

    great value

    By Simon on Mar 18, 2019

    My kitty also must take this for life. To the lady above who wishes it came with a rubber top for filling the syringe - any drug store has a plastic insert you can purchase.
