Thank you for posting your question can you also provide me with some more information as to:
How much Mirtazapine (dose) she is receiving?
Is this her first time being administered the drug?
What underlying condition does she have making her not want to eat?
How frequent have you been instructed to administer the medication?
I don't know the miligrams, but the dose is 1/4 a tablet every 3 days if needed. This would be the second time she would be taking it.
The first time she had to use it was after she came back from the vet after having a depostation. The vet said she lost her appetite due to the medication she was given that day. I used the mirtazpine only once that night and then her appetite resumed in full force.
Then we had to bring her back to the vet yesterday a second time this week just to be checked out and being a normally nervous cat, I think the stress of visiting the vet so soon after last week made her even more stressed and when she's stressed she doesn't want to eat.
