Hi there XXXXXXXX,
Thank you for your question regarding your 10lb boy who has ingested around 4mg of Pimozide some time ago. If he had eaten this tablet within the last 3 - 4 hours we could easily make him throw it back up, however it sounds as though he ate this quite some time ago - so this is not a possibility sadly. The good news is that Pimozide is actually sometimes used in Veterinary medicine to help control twitches that some dogs have after recovering from canine distemper. These dogs generally get a dose of 2 - 4mg once daily. Your boy is quite small so this is quite a large dose of the drug, however you shouldn't seen any severe side effects other than perhaps some listlessness and aggitation. He may develop some gastrointestinal signs, but hopefully your boy will be otherwise completely fine.
Do keep a close eye on him for the next day or two and if his condition deteriorates or becomes more lethargic, do get him down to your local Vet clinic for monitoring and supportive care.
Best of luck looking after your boy, don't panic and please reply if you need any further help.
Thank you for your question and please now click ACCEPT.
