Amitriptyline, also known by the brand name Elavil, is a tricyclic antidepressant drug used to treat conditions in dogs such as anxiety, behavioral disorders, and other problems. The drug works by increasing the amount of serotonin and norepinephrine in dogs’ brains by blocking reuptake of these neurotransmitters. When used to curb anxious behaviors, amitriptyline is often combined with behavioral modification programs for dogs that need them. Amitriptyline also works as a pain reliever for certain conditions. You should ask your veterinarian about the proper dosage and possible side effects before you use this drug to treat your dog. Here is what you should know about the uses, dosage, and side effects of amitriptyline in dogs.
Uses Of Amitriptyline In Dogs
Amitriptyline can be used in dogs to treat a variety of anxious behaviors, as well as certain kinds of pain. Here are some common conditions in dogs that amitriptyline might be prescribed to treat.
- Separation anxiety
- Obsessive grooming
- Depression over death of a companion
- Fear of loud noises
- Neuropathic pain from nerve injury, chronic cystitis, chronic purities, and skin irritations that cause itching
When used to treat anxious behaviors, amitriptyline should be combined with behavior modification until a dog can control unwanted behaviors without the need for medication. The dog should be weaned from amitriptyline when it is no longer necessary.
Dosage Of Amitriptyline For Dogs
The usual initial dosage of amitriptyline in dogs is 0.5 to 2 mg per pound, which should be given every 8 to 12 hours. While the drug is not FDA approved for use in animals, it can be given by a veterinarian safely. Symptoms may not clear up immediately, and it may take several days or even weeks for visible results.
