Amitriptyline Compound Basics

Amitriptyline Compound 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. This medication comes in various forms: capsules, chewable tablets, or oral suspensions.

Amitriptyline Compound requires a prescription from your veterinarian.

Amitriptyline Compound Directions

Use as directed by your veterinarian, and follow all instructions printed on the prescription label. Allow your pet access to plenty of water when giving this medication, and give doses with food. Complete the entire prescription unless instructed otherwise by your veterinarian. Dosage and duration of treatment depends on your pet’s condition and response to the medication.

Store at room temperature, protected from light and moisture.

Amitriptyline Compound Warnings

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 compound 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. 

Allergic Reactions and Serious Side Effects

Allergic reactions and serious side effects are rare, however, they can occur. In the case of an allergic reaction or a serious side effect, seek immediate veterinary attention. Some common signs of a more serious side effect are facial swelling, breathing difficulties, rashes or hives, pale gums, increased tendency to bruise or bleed, or low platelets.
