Metronidazole is an antibacterial and antiparasitic medication used to treat various conditions such as inflammatory bowel disease, nonspecific diarrheal disorders, infections caused by Giardia (a cause of diarrhea), and periodontal disease. Metronidazole requires a prescription from your veterinarian.
Give metronidazole exactly as it is prescribed by your veterinarian. Do not give in larger amounts or use it for longer than recommended by your veterinarian. Follow the instructions on the prescription label. If you do not understand these directions speak to your pharmacist or veterinarian. Your veterinarian may want to perform blood tests on a regular basis to make sure the medication is not causing harmful effects.
Seek emergency veterinary medical attention if your pet experiences any signs of an allergic reaction (hives; difficulty breathing; or swelling of the face, lips, tongue, or throat). Call your veterinarian at once if any of the following serious side effects occur: seizures; fever; chills; sores inside the mouth or on the lips; or watery or bloody diarrhea. Keep giving metronidazole and talk to your veterinarian if your pet develops any of these less serious side effects: nausea; diarrhea; dizziness; loss of balance; dry mouth; cough; sneezing; runny nose; or swollen tongue. Talk to your veterinarian about any side effect that seems unusual or that is especially bothersome to your pet.
Antibiotic medications can cause diarrhea, which may be the sign of a new infection. If your pet has diarrhea that is watery or has blood in it, contact your veterinarian. Do not use any medication to stop the diarrhea unless instructed by your veterinarian. Store metronidazole at room temperature away from moisture and heat.
