Answer

It seems your dog has ingested mirtazapine, a medication that can cause symptoms at higher doses, especially in small dogs. Your dog received 7.5 mg, which may be high for a 5.5 kg dog.

  • Watch for signs like increased heart rate, vocalization, or agitation.
  • Seek veterinary guidance if your dog shows any unusual symptoms.
  • If symptoms worsen, take your dog to the vet immediately.

Mirtazapine is sometimes used in veterinary medicine, but at controlled doses. At higher doses, particularly in small dogs, it can lead to adverse effects such as increased heart rate, vocalization, agitation, or sedation. While it has only been 15 to 20 minutes since ingestion, it's important to monitor your dog closely for any changes in behavior or health. Immediate veterinary attention is recommended if you notice any concerning symptoms.

If this is an emergency, please seek immediate veterinary care.
