Home Care and Prevention of Cat Metronidazole Poisoning

There is currently no specific home care for metronidazole poisoning in cats. If you suspect metronidazole is the cause of your cat's illness, consult your veterinarian immediately before discontinuing the medication. You may need to explore alternative treatments for the initial infection.

Always administer all medications to your cat according to your veterinarian's prescription. Unless your veterinarian specifically instructs otherwise, do not give your cat extra doses of metronidazole.
