Hi tony is on amlodipine for hi blood pressure and my vet is getting ready to start him on mirtazapine appetite stimulant so he’ll hopefully eat his kidney diet. Can mirtazapine affect his blood pressure? Thx
Mirtazapine is safe to use with amlodipine. Mirtazapine at high doses could potentially decrease blood pressure, but at typically prescribed doses, it is safe to give with amlodipine. Your vet may want to monitor blood pressure a few days after starting the mirtazapine just to be sure its all looking good. Thanks for asking Boop by Petco!

My senior dog started being restless and crying at night after giving her mirtazapine. I originally got it for her appetite, but it was also for mood elevation. I kept giving it to her after I saw that she kept crying at night, but now I’m scared she
I don't think this is serotonin syndrome. That dose is well within the safe range for Brandy. It may be anxiety, pain, related to another medical issue, or even cognitive dysfunction syndrome in dogs. I would recommend discussing this new issue with Brandy's vet. They may have some more insight on what could be the cause based on her medical history and recent physical exam. It may also be that the mirtazapine is not a good match with any other medications she is on. You could try a different appetite stimulant, called Entyce, which is specifically labeled for dogs.

Angel takes 15mg Mirtazapine daily as an appetite stimulant. I didn’t realize my boyfriend already gave it to her this morning and I just gave her another 15mg. She is approx 20 kg. Will she be okay? What should I do/watch out for?
The dosing does go up to 1mg/kg every 12 hours. So Angel's dose at this would be 20mg twice daily, so she should be absolutely fine. I hope this helps! Please let me know if you have any further questions or concerns and I would be more than happy to help you further.

my kitty was on Mirtazipine for appetite stimulant for 5 days and taken off-how long does the medicine stay in his system? He seems very sleepy and he was eating well on it of course but now not eating as much as he should and is very finicky. I was
Mirtazipine usually only stays in their system for 24-72 hours dependent on how high the dose was. If he was being dosed daily it likely was a small dose and will only be effective for approximately 24-36 hours. I would talk to your vet about continuing it. If they haven’t figured it why he isn't eating, then they may recommend additional diagnostics like blood work or X-rays. If you already know then you can continue mirtazipine longer until he is feeling better. And yes, he may have developed a preference for the tuna juice. You can continue to add tha to his other food. I hope this helps.

What are the side effects and adverse reactions of the medicine Mirtazapine in felines with stable kidney disease and a mega colon?
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.
