I just did a search on possible side effects here, but didn't find much.
Faust is supposed to take it for three days, starting yesterday. We have the granules, so I mixed them w/a little bit of canned food yesterday morning, and he ate his regular meals afterwards. Last night - major diarrhea. This morning some vomiting, also still diarrhea. He doesn't want to eat at all, but is acting fairly active/happy, and has been drinking a lot of water.
Up until yesterday poop was normal, so I suspect that the Panacur is really upsetting his stomach.
I called the vet... she's in emergency surgery and couldn't talk to me.
This is what the vet tech told me to do... force-feed/syringe the next dose of Panacur (mixed w/some wet food), don't let him gulp any more water (she said to put ice cubes in his water bowl and barely cover them w/water)... repeat the same process tomorrow, if he still won't eat on his own.
I know Panacur is only effective if the full dosage is given (for three consecutive days), but... REALLY???
I left a message for the vet to call me back by tonight, but if she doesn't - I'm thinking of just stopping the Panacur altogether for now, and see if his stomach will settle down. I'd already mixed his second dose w/some canned food this morning, so... I'm about to throw that out anyway instead of forcing it down his throat.
Any other ideas?
