What is Lactulose Solution?
Lactulose is used in cats and dogs as a laxative. Lactulose requires a prescription from your veterinarian.
Cats and Dogs
- Liquid is easy to administer
- No restrictions on food, drink, or activity unless otherwise directed by the veterinarian.
How it Works:
Lactulose is a disaccharide sugar composed of galactose and fructose. Unlike other sugars, its not absorbed into the blood. It passes unchanged to the large intestine. In the large intestine, lactulose is broken down by bacteria, resulting in the production of various acids. These acids draw water into the colon, softening the stool and increasing the volume, resulting in a laxative effect.
Side effects of lactulose include symptoms of flatulence, bloated stomach, and cramping. Diarrhea and dehydration are symptoms of overdose. Tell your veterinarian if your pet is diabetic, or pregnant or lactating.
Chronulac or Cephulac (Hoeschst-Marion Roussel), Constulose or Enulose (Alpharma)
What should I discuss with my veterinarian before giving lactulose to my pet:
Tell your veterinarian if your pet is diabetic. Tell your veterinarian if your pet is pregnant or lactating.
What is the most important information I should know about Lactulose:
Lactulose is a prescription medication that is not FDA approved for use in animals; however, it is a commonly accepted practice for veterinarians to use lactulose in dogs and cats as a laxative. Lactulose is available as a 10 Gm/15ml liquid. The usual laxative dose in dogs and cats is 1 ml per 2 pounds of body weight given every 8 hours initially, then use as needed. Notify the veterinarian if the pet develops excessive diarrhea.
How should this medication be given:
Give this medication exactly as directed by your veterinarian. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Lactulose may be mixed with fruit juice, water, or milk to improve the taste. It may take 24 to 48 hours before the effects of lactulose are seen. Lactulose may darken slightly in color. This change is harmless. However, if lactulose becomes very dark or uneven in consistency do not use the product. Store lactulose at room temperature, away from moisture and heat. Keep this medication away from children and pets.
What happens if I miss giving a dose:
Give the missed dose as soon as you remember. However, if is almost time for the next regularly scheduled dose, skip the missed dose and take the next one as directed. Do not give a double dose of the medication.
What should I avoid while giving Lactulose to my pet:
There are no restrictions on food, drink or activity unless otherwise directed by the veterinarian.
What are the possible side effects of Lactulose:
If any of the following serious side effects occur, stop giving lactulose and seek emergency veterinary medical attention; an allergic reaction (difficulty breathing; swelling of the lips; tongue or face; hives). Other less serious side effects may occur. Continue giving lactulose and talk to your veterinarian if your pet experiences flatulence, abdominal cramps, diarrhea or nausea and vomiting. Other side effects may also occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to the animal.
What other drugs will affect Lactulose:
Tell your veterinarian if your pet is being given an antacid as this may decrease the effects of lactulose. Drugs other than those listed may also interact with Lactulose. Talk to your veterinarian before giving your pet any prescription or over the counter medicines.

Excellent ..but if You Add it to FOOD, READ this
I gave this three stars to get your attention. It should be five stars but figured people are more likely to read the review if it has less and this is really important: according to my vet, if you add lactulose to food, you should only add it to a small amount (like a 1/4 can of fancy feast for example).
Then an HOUR LATER you can go ahead and feed the rest of the can. This is because adding lactulose to the food makes a lot of the nutrients pass through your cats system. So you have to let the lactulose do it's thing and then an hour later, give your cat it's normal meal (like the other 3/4 of the can of Fancy Feast) so that the food will be absorbed properly. If you feed the whole can with the lactulose, it won't get absorbed properly.
This product worked really well for my cat. It was recommended 1 ml in the a.m. and 1 ml at night. I did exactly as above - gave 1/4 can of Fancy Feast with the lactulose and then the remaining 3/4 can an hour later. At noon, he gets a whole can with no lactulose. Then at night he gets another 1/4 can with lactulose....and an hour later he gets the remaining 3/4 can.
I also give him a single serving of Sheba cat food (pate) at bed time as a treat (these are sold in two-part plastic packages. He just gets one of the two) It's very, very liquid-y and I'm sure it helps push things through as well!

Our cat has had issues with constipation for a long time! Finally we've found something that works great!! We do mix it with his soft food on a daily basis to keep him regular.

This is an excellent product
Our kitty was diagnosed with Mega Colon and had to have enemas fairly frequently. His stools were large and dry. He takes Cisapride (a tablet that we cut up and put into a gel capsule so it's easier for him to swallow). In addition, he takes 3ml. of Lactulose 3 times a day (1 dose before each meal). We give it to him using a syringe, but if your cat will eat food with meds in it, you can add it to your cat's food. Also, we add water to his canned food and feed dry food only as a treat. The dosage of lactulose can be increased if it appears your cat is constipated; but check with your vet to be sure he/she agrees. The lactulose keeps things "moving" along well and we get great service from 1-800-PetMeds so we never have to worry about running out.

My almost 17 year old cat has been on Laculose almost 2 years. His stool was so dry he was in emergency twice. Now that he has been on the medication, he is doing great, although he sometimes leaves me a 'nugget' outside of the box, but it's no longer dry and hard. I hope he lives another couple years but for now he's doing great.

Lactulose was first prescribed for Lusy because she has a portal shunt of her liver. She does very well with it and it seems to agree with her fragile system.
She is a laid back spoiled little girl!

my cat needs this med
Buddy was on deaths door with a sever blockage in his colon. With my vets help and lactulose solution he is in great health now. He will probably need to be on this medication for the rest of his life. Thank you pet meds for allowing me to purchase it in large amounts at an affordable price.

Gets the job done
Our big cat with mega colon hates Lactose and puts up a fight (with claws), when administered orally, but it really gets the job done. He doesn't eat it if mixed with food. We told him it was either this stuff or his life was going to be short-lived. It takes 2 of us to administer 6 cc daily. Without Lactulose solution, he would be totally blocked. He's 9 years old - acts like a kitten when he's regular - and really a loving and precious guy. I'm so greatful for this product, which I understand is safe for long-term use. I rate this product "5" for effectiveness, but not for taste (sweet syrup) and ease of use.

My (rescue) Lab Maggie has hepatic encephalopathy due to a damaged liver of unknown causes-- so her liver can no longer process protein, therefore the ammonia levels build up in her blood causing life threatening problems-- after a week in the ER hospital it now is under control with diet and 2 to 3 doses of lactulose daily to remove the ammonia. I am very happy with the results, she will have to remain on this medication for the rest of her life, thank goodness it is working for her and doing exactly what it is suppose to do-- I definitely recommend this product for this problem.
