Metoclopramide for cats is a medication that works on the gastrointestinal system to stimulate the movement of the stomach and small intestine, and inhibits and treats vomiting that arises from various medications, treatments or surgery. Metoclopramide is what is known as a dopamine antagonist.
Dosage: Dogs and Cats: 0.2-0.5 mg/kg every 6-8 hours orally, IV or IM, or 1-2 mg/kg every 2-4 hours by continuous IV infusion, or approximately 0.1-0.2 mg/kg every hour. Horses: 0.125-0.25 mg/kg/hr IC [added to IV fluids]. Metoclopramide is best given 20 minutes before a meal.
Dosing Information of Metoclopramide HCl for Dogs and Cats

In dogs and cats, the typical dose administered is 0.1 to 0.2 mg per pound (0.2 to 0.5 mg/kg) every six to eight hours orally, subcutaneously or intravenously. Metoclopramide is commonly added to intravenous fluids in hospitalized dogs to help prevent vomiting.

Do not stop giving the medication to your pet without first speaking with your veterinarian. This medication should take effect within one to two hours; however, its effects may not be visibly noticeable.
How long does it take to work? Metoclopramide tablets and liquid usually start to work after 30 to 60 minutes. How does it compare with similar medicines? Metoclopramide belongs to a group of anti-sickness medicines called anti-emetics.
If your cat has an acute case of vomiting, this may involve a temporary change to an easily digestible diet, such as Royal Canin Gastrointestinal High Energy cat food, Hill`s ID cat food, or a bland human food such as meat-flavored baby food (with no onion or garlic powder added) or boiled chicken.
The name of your medicine is Metoclopramide Hydrochloride 5mg/5ml Oral Solution (known as Metoclopramide in this leaflet). This belongs to a group of medicines called antiemetics. Metoclopramide works on a part of the brain that prevents you from feeling sick (nausea) and being sick (vomiting).
Metoclopramide Overdose Information

Metoclopramide has a wide range of safety. However, large overdoses can cause drowsiness, incoordination, vomiting, and constipation. Serotonin syndrome can occur with overdoses of this medication depending on what other medications your pet may be on.

Place the tablet in the mouth and allow it to dissolve, and then swallow. You do not need water to take this medication. Do not take your medication more often than directed.
You can take metoclopramide with or without food. Swallow the tablets whole, with a drink of water. If you`re taking metoclopramide liquid, use the plastic syringe or medicine spoon that comes with your medicine to measure out the right dose.
Overall, metoclopramide leads to increased gastric emptying by enhancing antral contractions as well as decreasing postprandial fundus relaxation [34].
These studies in cats demonstrated that it is an effective appetite stimulant. The dose is usually 1.88 mg per cat oral. At high doses it produces adverse effects that include vocalization and increased restlessness. In cats it has a half-life of approximately 10 hours, which allows for once-daily dosing.
Take this medicine on an empty stomach, at least 30 minutes before meals and at bedtime. If you are using the disintegrating tablet, make sure your hands are dry before you handle it. Do not open the blister pack that contains the tablet until you are ready to take it.
Metoclopramide takes about one to three minutes to start working following an intravenous dose; 10-15 minutes following an intramuscular dose; and 30-60 minutes following an oral dose. Effects last for approximately one to two hours.
Re-hydration is important after vomiting, but most vets recommend waiting around two hours after an episode of vomiting to offer your cat any water or bland food. Don`t let your cat eat their expelled vomit, even if they try.
Adverse effects occasionally reported with metopimazine include sedation, orthostatic hypotension and anticholinergic effects. Extrapyramidal symptoms, including dyskinesias, are very uncommon [79].
Medicines that treat nausea and vomiting are called antiemetics. Several OTC medicines are used as antiemetics. These include: Bismuth subsalicylate (2 brand names: Kaopectate, Pepto-Bismol).
Metoclopramide is indicated in adults for: – Prevention of delayed chemotherapy induced nausea and vomiting (CINV). – Prevention of radiotherapy induced nausea and vomiting (RINV). – Symptomatic treatment of nausea and vomiting, including acute migraine induced nausea and vomiting.
Symptoms of overdosage may include drowsiness, disorientation and extrapyramidal reactions. Anticholinergic or antiparkinson drugs or antihistamines with anticholinergic properties may be helpful in controlling the extrapyramidal reactions. Symptoms are self-limiting and usually disappear within 24 hours.
There is no treatment for tardive dyskinesia, but in some cases the symptoms may lessen or stop once metoclopramide is stopped. Warnings: This medication may cause a serious movement disorder called tardive dyskinesia. In some cases, this condition may be permanent.
This drug has a black box warning. This is the most serious warning from the U.S. Food and Drug Administration (FDA). A black box warning alerts doctors and patients about drug effects that may be dangerous. Reglan can cause a serious movement disorder called tardive dyskinesia (TD).
If a pill does get stuck, never let it stay there to dissolve. Many medicine will irritate your throat. A glass of water should free even the stickiest capsule. Eating some food after swallowing a pill makes sure that it goes down.
Intravenous injections of undiluted metoclopramide should be made slowly allowing 1 to 2 minutes for 10 mg since a transient but intense feeling of anxiety and restlessness, followed by drowsiness, may occur with rapid administration.

Q. My dog has CHF and is on heart and lasik pills twice a day. I can’t get him to take his pills since yesterday morning, I hear him gurgling
ANSWER : A. If your dog is refusing his pills you may need to get creative in how you give them. Many pet stores offer commercial “pill pockets” where you can hide the pills in a treat. Using cheez whiz, chicken pieces or even hamburger meatballs with the pills hidden inside may encourage him to eat it as well. You can also place the pill in the corner of his mouth toward the back, and then give a squire of water with a syringe to cause him to swallow the pill. If however he appears to not want to take his pills due to worsening illness, or he has changes in his symptoms, contacting your regular veterinarian is best.

Q. I recently added a new 2 month old female kitten to my house and my male 5 month the old kitten has turned aggressive and chases the kitten down..
ANSWER : A. It is possible it could be play behavior but without seeing it in person, hard to say. Is the male kitten neutered? You may want to consider doing so. Also, try re-introducing the kittens slowly by creating a safe space for the new kitten behind a closed door in a room. Keep her there for at least a week so she is protected but your male is still able to smell her. After a week or 2, you can then graduate to using a baby gate so they can then not only smell each other but safely see each other as well. If that is going okay, after another few days you can bring the gate down. Also, be sure to have feeding bowls in separate locations and at least 2 litter boxes.

Q. I have a 1yr old male 38 lb Labradoodle and my gf just brought a month old kitten home. Can they interact? If not, for how long?
ANSWER : A. Interactions whenever a new pet is brought into the house should start off slow, then can be increased in time. The best steps when introducing a new cat is to allow your cat or kitten to have a room in the house all to him or herself. Allow your dog to sniff under the door to get used to the kitten’s scent, and even show your dog articles such as bedding the cat has slept on. After a few days, an introduction with your dog on leash, or a barrier such as a gate where both pets can look at each other but not see each other is best. This will allow each to get used to seeing the other without the ability to jump, bite or scratch the other. Once the two are used to this, then a face to face interaction can begin. If at any time a fight or scuffle breaks out, separate the two pets and try again at a later time. The amount of time this introduction takes can vary depending on how the two react to each other.

Until your kitten is older, or you are sure both are fine together, do not leave the two pets together unattended. Even a well-meaning and playful dog can accidentally break a leg of a kitten or worse without meaning to! A safe room for your kitten to be in while you are away, or a barrier to allow your kitten to escape to safety if needed will help until both are big enough to play alone safely.

Q. My dog has been throwing up a clear liquid (a little slimey) but otherwise acts fine. Could something be wrong?
ANSWER : A. How long has he been doing this? Ongoing vomiting (>2 weeks) warrants a vet visit, but if it’s a one-off, or happens very infrequently then it could be due to something he ate disagreeing with him. Is he is bright, alert and happy in himself I would monitor him, start keeping a vomit journal (seriously) of when he vomits, how much, what the vomit was like, what he was doing before and any other notes. This will be really useful for your vet if it requires further investigatoon. You can also try bland food – boiled chicken and white rice – in small amounts on his vomit days to give his tummy a rest. Withhold for 8h after a vomit and reintroduce the bland diet in small, frequent meals.

Q. My daughter has three kittens, 5 weeks old. All of a sudden two of them are vomiting and having trouble having bowel movement
ANSWER : A. If your kittens are experiencing a sudden change in health such as inability to have a bowel movement or vomiting it is best to schedule an appointment with your local vet for care. Vomiting, especially in young cats, can quickly cause dehydration and more health problems. Your vet will likely examine the kittens for any signs of illness, and may also recommend an X-ray to check for a stuck object in the body, or bloodwork to check for internal disease. Subcutaneous or IV fluids may also be given to help stop any dehydration and get the kittens feeling better.

Q. How much dry kitten food should my 16 week old kitten be eating?
ANSWER : A. It would actually be better to feed your kitten canned food, as dry food has a lot of carbohydrates. Cats are obligatory carnivores, and not carb-eaters. In order to give you an amount to feed for dry food I would need to know which food you are feeding as they are all different. I suggest you check on the cat food bag. If the bag does not give you an amount, I would not trust it to be a complete food. You should then get a food from a reputable company such as Hill’s Science diet, or similar. As for wet food feed three times daily around 2oz each time, best to feed the pate style food.
