Practical Matters: Use caution when prescribing transdermal medications for feline behavior problems
When prescribing transdermal medications, only consider drugs that are proven effective when used transdermally or that have an objective, measurable response to treatment. For example, the efficacy of transdermal methimazole for treating hyperthyroidism can be confirmed through the resolution of clinical signs and by measuring serum thyroxine concentrations.
Thus, when prescribing medications for fussy cats, work with your compounding pharmacy to see what formulations are available. But save the transdermal behavioral drugs as a last resort for cats that will not tolerate oral medication.
