Amitriptyline is highly toxic to both dogs and cats. Even a small number of human tablets can cause severe neurological and cardiovascular effects, including seizures, abnormal heart rhythms, and death. Keep all prescription medications in a secure cabinet away from pets.
Pets are most often exposed by chewing through pill bottles, eating dropped tablets, or being accidentally given a human medication. Signs of poisoning can appear within minutes to a few hours and may worsen quickly.
If you suspect your pet ate amitriptyline, treat it as an emergency. Contact your veterinarian or an animal poison control center immediately, and bring the medication bottle with you.
To prevent poisoning, store all antidepressants out of reach, pick up dropped pills right away, and never give your pet a human medication without veterinary guidance.
