Dosage: 0.5-1 mg/kg orally up to three times a day, or 4 mg for a small dog and 8 mg for a large dog. Indication/s: This can also be an expensive medication. However, it is a great first-line or second-line treatment for dogs with mild to severe inappetence, nausea or vomiting.
Are there any potential side effects?
Side effects are uncommon. Rare side effects may include constipation, sleepiness, or head shaking. Rare but serious side effects include abnormal heart rhythms and low blood pressure, which may cause fainting/collapse or severe lethargy.
This short-acting medication should stop working within 24 hours, although effects can be longer in pets with liver or kidney disease.
Are there any risk factors for this medication?
Ondansetron should not be used in pets that are allergic to it. It should be used cautiously in pets with gastrointestinal blockage, certain abnormal heart rhythms, or liver disease. Ondansetron should be used with caution in pregnant or lactating pets as safety has not been clearly established.
Some breeds of dogs (e.g., collies, sheepdogs, and collie- or sheepdog-cross breeds) are more sensitive than others to medications. This is typically due to a specific genetic mutation (MDR1) that makes them less able to tolerate high doses of certain medications. Therefore, ondansetron should be used cautiously in these cases.
