Mirtazapine is a prescription tablet generally used as an appetite stimulant and anti-nausea drug in sufferers of chronic kidney disease or stomach disease. It increases appetite by blocking signals from the intestine and stomach to the brain. Veterinarians may use this for the treatment of companion animals. Customers may receive this drug under the name Remeron.


Mirtazapine Tablets are used to help treat conditions where poor appetite and nausea occur simultaneously.

Possible Side Effects

Mirtazapine may cause a drop in blood pressure or an elevation in heart rate. Drowsiness and serotonin syndrome are potential side effects. Occasionally, mirtazapine has been reported to cause abnormalities in blood cell lines developing in the bone marrow. If a pet is known to have leukemia, low platelets, or some other blood disease mirtazapine can still be used but extra monitoring tests are probably in order.

Drug & Food Interactions

Mirtazapine should not be used in pets with hypersensitivity to mirtazapine or that have received monoamine oxidase inhibitors (eg, selegiline) in the past 14 days.


Mirtazapine should be used with caution in pets with known cardiac disease or cerebrovascular disease that could be exacerbated by hypotension. Pets with renal impairment, renal failure, or hepatic disease may require lower doses of mirtazapine and should be monitored while on mirtazapine therapy.

This drug is FDA-approved for human use. However, it is common practice for veterinarians to prescribe such drugs for use in dogs and cats.

    Helped my cat a lot

    Took my cat to the vet because she was vomiting and had diarrhea and wasn't eating much. Vet prescribed antibiotics and this. She got her appetite back quickly.
