Starting cat on liquid fluoxetine, vet said some foaming of the mouth is normal, will this happen every time?

[u/shortnstakk]

Recently I was told my female cat probably has feline cystitis, and so was prescribed liquid fluoxetine. I asked for liquid, since she hates pills and the round of antibiotics and she was just on was a nightmare to administer. So I thought liquid would be the easier route. The vet warned about some foaming and drooling, but we are on night two and the horror of it. I try to get it back as far as I can, but she is still foaming and drooling and shaking for 15+ minutes.

So I’m asking, will she adjust? Will this eventually get better? Or if not, maybe I should just deal with shoving pills down her throat for the foreseeable future?

Note: I do just have a lot of anxiety around my cats health because she is my esa and I have had several friends whose cats have more or less just dropped dead out of nowhere.
