Lactulose Solution Description
Constipation is a painful problem for your pet. Talk to your vet about Lactulose, a prescription laxative used to treat constipation in dogs and cats. It works quickly to relieve the pain and frustration associated with constipation. Lactulose can also be used to treat and prevent a liver disease called portal-systemic encephalopathy.
Laactulose Solution is the Generic Alternative to Generlac.
Side Effects and Warnings
Side effects of Lactulose include flatulence, bloated stomach, and cramping.
Lactulose may alter the insulin requirement in diabetic animals.
Use Lactulose with caution in animals with fluid or electrolyte imbalance.
Contact your veterinarian if your pet is producing less than 2-3 soft stools per day or if the condition worsens.
Diarrhea and dehydration are symptoms of overdose.
Symptoms of an allergic reaction may include: facial swelling, vomiting, diarrhea, cold limbs, shock, seizures, pale gums, hives, scratching, or coma.
Contact your veterinarian if your pet is exhibiting any of these symptoms.
Tell your veterinarian if your pet is taking any other medications or supplements. Do not use this product with other laxatives. Oral antacids may reduce the effectiveness of Lactulose.

Rated 5 out of 5 by HappyKat123 Keeps my cat running smoothly!
My cat kindly takes it mixed in her food making it easy for me to dose her. She doesn't seem to mind the orange flavor and it's cheaper than the plain.

It's convenient and cost-saving to be able to purchase this larger bottle of Lactulose instead of running to the vet for the small bottles. I always receive the Lactulose in a timely fashion and consider it a good value. It does help my elderly cat Puffy as a stool softener, along with Cisapride, for her megacolon.

Rated 5 out of 5 by catlady27 Very effective product that is also easy to dispense.
After my cat was diagnosed with megacolon the vet prescribed Lactulose.

Rated 5 out of 5 by Verified Reviewer The worst product in the world
My cat with megacolon was put on this product. It never worked and his megacolon got much worse. I found the megacolon users group on yahoo and they all recommended the use of Miralax instead. WOW, that worked.

Rated 5 out of 5 by Verified Reviewer Lactulose is great!
My female dog was born with an unnatural dip in her colon and sometimes waste gets balled up and she would have to stretch herself out to loosen it or she gets constipated. Since using Lactulose, she has been able to "go" much easier without all the stretching.

Rated 5 out of 5 by Verified Reviewer Works as expected and the price is UNBELIEVABLY low!
This was prescribed by my local vet for my 14-ish year old cat Samael, who has bowel problems due mainly to old age. He couldn't "go" and was so backed up that he almost didn't make it. Now using this product as prescrbed (2.5 cc's in the mouth EVERY 8 hours for the rest of his life... d'oh!) has made him quite regular again.
PetCareRx has a GREAT price on this product! My local vet & the pharmacy they use charged me $40 for a 4oz bottle, while here at PetCareRX I can get a 16oz bottle for only about $16 and a couple bucks to cover shipping! $10 an oz VS about $1 per oz, WHAT A GREAT BARGAIN! Thanks PetCareRx, without you I don't know if poor kitty would be able to stay medicated and 'regular'! You have literally saved his life (and my wallet!) *This is a prescription item
