My cat is constipated while on mirtazapine. Can I give her cisapride?
Hello, thank you for using Petco Pet Education Center, formerly Petcoach. There are no known contraindications with using mirtazapine and cisapride together but remember, all cats react differently to medications so if you notice any abnormal issues then stop the medications immediately and call your vet. Hope this helps. Best wishes.

Is Mirtazapine safe for cats with kidney disease and megacolon?
Mirtazipine can cause serotonin syndrome which is characterized by hyperactivity, muscle tremors, vocalization and behavior changes. This is more likely at high doses but has been reported to occur at typical doses as well. It is cleared through the kidneys so a dose reduction is typically recommended for cats with decreased kidney function. Megacolon should not be a concern.

Do Cerenia & Mirtazapine help my cat's appetite and balance issues?
Thanks for using Petco Pet Education Center, formerly Petcoach. I'm sorry to hear Katniss has been ill. Cerenia is an anti-nausea medication. Animals with vestibular disease often feel "motion sick" - having something similar to vertigo. So this is great for that. It also helps settle the stomach which helps with appetite. Mirtazapine is a true appetite stimulant. Even with both of these, the balance apparatus is very mad and so falling over may still happen. I recommend bringing slightly warmed wet food to his face a few times daily to encourage eating. If no improvement in the vestibular signs within a week, I recommend a CT scan of the head to look for inner ear infection or, heaven forbid, a tumor. Vaseline is ok for paw pads, though olive oil or coconut oil is even better. To be honest, most cracked paw pads are not painful and do not need treatment. I'd recommend an over the counter laxatone product for the hair balls, along with frequent brushing. Omega 3 fatty acid supplements can help with the dandruff. Best wishes to you and Katniss.

My cat ate my antidepressant. She's drowsy. Is this an emergency?
Mirtazapine does have a side effect of drowsiness or sedation in pets. It is commonly used in cats as an appetite stimulant. 30mg would be 4 times higher than I normally use, and this overdosage can cause: 57% vocalizing, 38% agitated, 23% vomiting, 21% tachycardic, 15% ataxic and 11% lethargic. The symptoms can last a little longer than 72 hours. As long as Dolly is still eating and drinking normally, I would continue to watch her. If the she is still not completely normal in a day or two, she may need a checkup with a vet.

Is it safe to give a cat MiraLax when they are on prednisone?
This drug can be a little tricky when giving it. Your pets complete medical history should be known before starting this laxative, due to possible complications that can ensue. Because of this, I would not continue its use without consulting with Dewey's primary care veterinarian. It is used in veterinary medicine, but it has certain requirements and cautions with use. Also it should always be dissolved and not given in powder form. As a side, Prednisolone does not have constipation as one of the possible side effects to using this medication. If she is constipated, then there is likely another underlying cause. Best of luck moving forward with your pet Dewey. Take care.
