Product Info:

Amitriptyline treats behavioral disorders in cats and dogs. Behavioral disorders include separation anxiety, generalized anxiety, excessive grooming, and urine spraying. Amitriptyline belongs to class of drugs known as tricyclic anti-depressants. It increases the levels of serotonin and norepinephrine, two important neurotransmitters. It also causes sedation and blocks the neurotransmitter acetylcholine from uptake.

Keep out of the reach of children and pets. Do not use in pets with known hypersensitivity to amitriptyline or in pets that are pregnant or lactating. Use with caution in animals with seizure disorders, diabetes mellitus, liver disease, or heart disease. Amitriptyline may interact with some other medications. Therefore, inform your veterinarian of any medications your pet may be taking. This is especially important if your pet is currently taking other drugs that act as Central Nervous System (CNS) depressants, some thyroid medications, sympathomimetic agents, and cimetidine. Weight gain may also occur in some cats using this medication. If you notice any behavioral or physiological changes in your pet while administering amitriptyline, contact your veterinarian immediately. Finally, overdoses of amitriptyline are serious and can be very toxic. If you suspect your pet has been given too much amitriptyline, call your veterinarian immediately.
