Increased Nausea and Vomiting

So this did help increase my cats appetite. She went from eating half a can of wet food per day to 2 cans of wet food per day (she only eats wet food). For a cat with hyperthyroidism and chronic kidney disease that's definitely a godsend. However, a week or two after putting her on it she had two bad vomiting spells where she vocalized for hours and foamed at the mouth. Apparently a symptom of this medication can be increased nausea, vomiting, and vocalization. I have her ondansetron now while I figure out with the vet if a different appetite stimulant would be better. Obviously ymmv with this medication.

Great to get my dog with cancer eating

My 65lb dog has cancer and is in the end of her life. She stopped eating and lost a bunch of weight. I started giving her one of these and 1-3 hours later she begs for food!

Benefits of Mertazapine

Our 7 year old Morkie stopped eating suddenly several months ago and after many tests, ultrasound, etc. the Vet that did the ultrasound prescribed Mertazapine as an appetite stimulant and it worked instantly. We almost lost Pepper inasmuch as she stopped eating "anything" , i.e. snacks, her regular food, etc. etc. simply would not eat. Pepper is now eating 2 meals a day, snacks, etc. and is happier than she has ever been. We are forever grateful for the Vet that did the Ultrasound and for prescribing Mertazapine and for Chewy providing the medication to us.

Excellent Remedy for Blue who had stopped eating

My 18 year old Cat True died in March and her sister Blue was in mourning and had stopped eating. This drug was prescribed by my vet, Dr Cohen, and Blue has started eating again...I am so grateful to you Chewy ..you have always been and are there for me, Warm Regards, Judy

Help for appetite

I have an aging cat with thyroid and kidney disease who needs help increasing her appetite. She has lost half her body weight over the course of almost two years, so needs to eat more. A small dose of Mirtazapine every two days increases her appetite enough so that she can function more normally. Plus, she is maintaining her weight and muscle mass.

GREAT for appetite!

This works great as an appetite stimulate for my girl (miniature poodle). She use to use Entyce, which is great. But expensive.

Works great...watch out for howling

My old cat has kidney disease and hardly any interest in food. This pill works wonders and makes a huge difference in his appetite. One of the side effects is increased vocalization - which is definitely present a couple hours after my cat takes the pills. It causes VERY loud meowing, he appears a little confused and his ears become quite red (my vet says these are normal). But he eats like a champ! I woke up to an empty food bowl for the first time in his life!

Way cheaper than at the vet

So my cat has hepatic lipidosis. And she won’t eat or drink. We have to syringe feed, give her IV fluids subcutaneously, etc. And she can’t take pills for whatever reason, they’ll get stuck in the back of her throat for like up to a day, she’ll vomit, spit them out, or drool them. We’ve tried compounded too. I wanted to get this in transdermal form, but I can’t afford it because I’m spending over $150 monthly just to keep her alive and you’re supposed get like 3.75 mg and give it 3 or every other days to, and it’s like a battle with her just to eat. But this pill, it’s like the only thing that got her to eat consequently for 6 days. It only lasted for 6 days. Now we’re at three and hoping for more. We just crush one whole pill in her A/D and she like literally spits and drools half of her food out, so we don’t know how much of the pill she is getting, but it’s working. We’ve tried it with water or a pill popper, and she’ll like just vomit/spit/drool the whole thing out. She doesn’t want it in a greenie or pill paste. So if anybody is reading this and is having the same issue with their cat, we’re currently 6 1/2 weeks in and our cat is still alive.

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.
