It is important to use the medication we are prescribing for your pet. If you have concerns about anything you find on here, please contact our office at 518-446-9171 before stopping the medication.
What is metoclopramide?
Metoclopramide (brand names Reglan® and Maxolon®) is used in dogs, cats, and small mammals to stimulate stomach and upper small intestinal movement to prevent esophageal reflux, a condition where stomach acid backs up into the throat and esophagus (the muscular tube connecting the throat and stomach). It is also used in the treatment or prevention of vomiting in dogs and cats. Metoclopramide is also used in dogs and cats to induce milk let-down and to promote milk production.
The use of metoclopramide in dogs, cats, and other animals is off-label. Many drugs are commonly prescribed for off-label use in veterinary medicine. In these instances, follow your veterinarian’s directions and cautions very carefully.
How is metoclopramide given?
Metoclopramide is available as a tablet and an oral syrup. It is also available as an injection that your veterinarian will administer under the skin, especially if vomiting is a concern. Your veterinarian may direct you to inject this at home. Be sure to understand the proper dose, location, and technique if you are administering this drug by injection.
Oral tablets and syrup may be given by mouth with or without food. If giving it on an empty stomach or before a meal, give it approximately 15-30 minutes prior to feeding. If vomiting occurs after taking the medication on an empty stomach, try giving the next dose with food. If using the liquid form and vomiting occurs after dosing, wait until the next scheduled dose. Liquid forms of metoclopramide must be measured carefully.
It is very important to give the medication for the length of time your veterinarian has recommended. 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.
What if I miss giving my pet the medication?
If you miss giving your pet a dose, give the next dose as soon as you remember, but if it is close to the next dose, either:
• skip the dose you missed, give it at the next scheduled time, and continue with the regular dosing schedule, OR
• give the missed dose when you remember and then wait the recommended interval before giving the next dose (continue giving it regularly at that new time).
Never give your pet two doses at once or give extra doses.
Are there any potential side effects?
There are very few side effects of metoclopramide.
The most commonly reported side effects in dogs are restlessness or hyperactivity, spasms or twitching, drowsiness, constipation, and increased urination. The most commonly reported side effects in cats are disorientation, constipation, and hyperactivity or frenzied behavior. These effects are usually not very serious. Contact your veterinarian if they worsen, become severe, or continue.
More serious side effects that indicate a problem are aggressive behavior in dogs, severe restlessness, twitching, or sleepiness. If you notice your dog has threatening behavior, contact your veterinarian immediately.
This short-acting medication should stop working within 24 hours, although effects can be longer in pets with liver or kidney disease.
