Onset of action is 4 or more weeks. The dose of Clomipramine may need to be increased from an initial dose rate once daily, to a higher dose rate if initial response is insufficient after 6-8 weeks. Higher doses are associated with increased adverse effects such as sedation and it is important that genuine response to therapy is not confused with undesirable profound sedative effects which will suppress all sorts of behaviour.

Sensitivity of cats to TCAs is generally higher than in dogs as they use glucuronidation to metabolise them<ref>Overall, K.L., 2004.

Once the condition being treated is deemed under control drug therapy should be gradually phased out over approximately 4-8 weeks. This is preferable to stopping administration of a drug all at once and reduces potential central withdrawal signs, as well as allowing establishment of the lowest dose that is still effective if problem behaviour is resumed during the weaning process. Although treatments are long term, maintenance doses are generally significantly lower than doses used at the beginning of the treatment regime. Successful drug therapy should produce around 70% reduction in the behaviour and an increase in normal activity as a substitute.

If the drug is overdosed/combined with an inappropriate drug (see above) an increased sedation and degree of adverse effects as listed will be seen. If the drug dose is persistently high or the drug is combined with an MAOI, serotonin syndrome is a possible consequence:
