Effects of feeding Metrogyl tablet to cats

Hi,

I am from India.

I have a male cat who is now 2 and a half years old. He has been having diarrhoea for the past couple of months. We went to a vet one evening and he prescribed a half tablet of Metrogyl 400mg and a half tablet Neurobion Forte (vitamin B12) twice a day. That night we fed him both the tablets (by dissolving the tablets in water and giving it to him via a syringe). The next day, he started having reactions to the tablet.

He stopped eating, was walking weirdly (felt as if he had muscle pain in his legs or something), seemed mentally confused and listless.
He likes eating fish madly. We gave him some, but he just would not eat at all ! We gave him some milk as well, but he just would not drink that as well, too ! He drank some water of his bowl after some time.

He had trouble sleeping also, he did not sleep ALL DAY ! ...

We stopped giving him that medication after that night.

It has been 3 days now and he just would not eat ! ... my mom gives him fish, but he just eats only a small amount. He seldom drinks water.
And he just would not sleep in these 3 days ! He just stays awake all day and night. We tried taking him under our blanket, but still he would not sleep. He somewhat keeps his eyes half closed.


Can anyone here give me any advice about what I should do ? Did anyone have the exact same problem with their pets ? ... 
WHEN WILL THE SIDE EFFECTS TO THE METROGYL AND NEUROBION FORTE TABLETS WEAR OFF ??

I am literally crying while writing this post. :'(

Please help ! Anyone ! 

 

Metronidazole is the active drug in Metrogyl tablets and it can have side effects such as nausea which will put the cat off his food, and rarely neurological side effects.  If he were my cat, I would take him back to the vet, tell him about the neurological symptoms and ask that he be given a dose of fluids SubQ to help flush the drug out of his system more quickly because it take a long time with only the normal amount (or less than normal) of fluid an animal consumes.  You might also ask your vet to try an anti-nausea medication to try to improve the appetite.  If your cat is still having neurological symptoms, he may be nauseaous because he is dizzy.  I had one cat who did have this kind of sensitivity and the vet prescribed meclizine, which is the equivalent of the human drug Antivert, and it did help him a lot.  Definitely go back to the vet and don't let him be miserable any longer.  He is obviously one of those cats who is extremely sensitive to this type of drug, as mine was, and he needs help to feel better.  Let us know how he does.
