Prepared to a veterinarian's order for one animal patient. Not FDA-approved.
No FDA-approved animal drug contains amitriptyline; Animal Drugs@FDA returns no amitriptyline products. Amitriptyline is an FDA-approved human tricyclic antidepressant, labeled for the relief of symptoms of depression in people. The Merck Veterinary Manual notes it has been given to dogs for separation anxiety, anxiety-related aggression, some urination behaviors and allergy-related itch, and to cats for urine marking and excessive vocalizing. These are not FDA-approved uses in animals. Compounded preparations are not FDA-approved and are dispensed only on a veterinarian's prescription for an individual animal.
The Merck Veterinary Manual lists side effects of tricyclic antidepressants in animals including vomiting, diarrhea, excitability, sleepiness, fast or irregular heartbeat, wide pupils, dry eyes and mouth, trouble urinating, constipation and weight gain. Too much can affect the heart, so keep all doses out of reach of pets and call your veterinarian if an animal eats extra. The human label says amitriptyline must not be given with MAO inhibitor drugs or with cisapride, because of risks such as dangerous fever, seizures and heart rhythm problems. Ask your veterinarian or pharmacist about other medicines and supplements your animal takes.
With no approved animal product, use of amitriptyline in companion animals is extralabel use of an approved human drug, permitted in nonfood-producing animal practice under 21 CFR 530.30 except when public health is threatened; compounding from an approved human product falls under 530.13(b), and 530.13(a) excludes compounding from bulk. Amitriptyline does not appear on FDA's GFI #256 office stock list (updated 10/05/2026). The human label carries a boxed warning on suicidality in young people and contraindicates use with MAO inhibitors and cisapride. Merck cites QRS widening with tachycardia as an early sign of toxicosis. No FDA CVM safety communication was found.

Compounded preparations have no NDC, so this formula will not appear in your EHR's drug search. Use your system's compound, non-formulary, or free-text prescription entry and name the preparation exactly as written in step 3. If your EHR forces you to pick a listed drug, pick the closest entry for the active ingredient and put the full formula in the prescription body (the Sig or directions field), not in Notes to Pharmacy.
Compounded preparations have no NDC and will not appear in your drug search. For EPCS to validate, select a drug entry your EHR recognizes as controlled, usually the bulk powder entry for the active ingredient (for example Ketamine (bulk) powder, not a branded product), then put the full formula from step 3 in the prescription body. A free-text entry that does not validate as controlled will be rejected by your EPCS module.
Quantity and directions are starting points for this dose form, not treatment recommendations. Dosing remains the prescriber's responsibility.
