Clomipramine Hydrochloride Tablets do not act as a sedative.

Clomipramine Hydrochloride Tablets belong to the dibenzazepine class of tricyclic antidepressants. Clomipramine hydrochloride is 3-chloro-5[3-(dimethyl-amino)propyl]-10,11 dihydro-5H dibenz[b,f] azepine monohydrochloride. Clomipramine Hydrochloride Tablets are oblong, light brown in color and contain clomipramine hydrochloride formulated together with meat components.

Indications and Usage:

Clomipramine Hydrochloride Tablets are to be used as part of a comprehensive behavioral management program to treat separation anxiety in dogs greater than 6 months of age. Inappropriate barking or destructive behavior, as well as inappropriate elimination of (urination or defecation) may be alleviated by the use of Clomipramine Hydrochloride Tablets in conjunction with behavior modification.

Separation anxiety is a complex behavior disorder displayed when the owner (or other attachment figure) leaves the dog. In the absence of the owner or attachment figure, dogs with separation anxiety may exhibit one or more clinical signs. The signs of separation anxiety evaluated in controlled trials were vocalization, destructive behavior, excessive salivation, and inappropriate elimination. Although it may appear that this behavior, which only happens in the dog owner’s absence, is a spiteful action, this behavior is thought to be a result of anxiety experienced by the dog. Therefore, punishment would not be appropriate for the dog with this behavior.

Behavior Modification (Training):

Behavior training is a necessary component of therapy with Clomipramine Hydrochloride Tablets. In clinical trials, specific behavior training techniques were used at the following times:

  • when the owner interacted with the dog while at home
  • when the owner was preparing to leave the home
  • when the owner returned home and greeted the dog

Since the methods used for behavior training can vary according to patient needs, it is important that you follow the instructions provided by your veterinarian regarding the specific techniques recommended for modifying your dog’s behavior.
