Safety precautions

  • Do not give mirtazapine to dogs with known allergies to the substance
  • Do not give mirtazapine to dogs who have swallowed a toxic substance
  • Avoid use in dogs who are taking antidepressants unless advised otherwise by your vet
  • Notify the vet of any other medication your dog is taking
  • Notify the vet of any medical conditions your dog suffers from

If you fear your dog is having a bad reaction to the drug you should seek veterinary help to prevent symptoms from getting any worse.

Side effects of mirtazapine use in dogs

 
Side effects of mirtazapine for dogs is rare, though hyperactivity is noted in some cases and on a more serious note it may cause serotonin syndrome.

If your dog shows any other signs of serious negative reactions to the drug you should stop administering it immediately and seek emergency veterinary attention. Look out for signs of allergy, which includes labored breathing, rashes and hives.
