Clofazimine is a fat-soluble riminophenazine dye used in combination with rifampicin, moxifloxacin and dapsone as part of a multidrug therapy for canine mycobacterial granulomas[1].

Clofazimine is highly lipophilic and possesses and unusually long pharmacokinetic half-life of up to 70 days[2] associated with extensive accumulation of the drug in the body[3].

Although not always successful in chronic cases[4], it has also been used as a topical formulation in petroleum jelly as an adjunct to oral rifampicin and doxycycline in mycobacterial granulomas[5].

Recommended dose rate in dogs is 4 - 8 mg/kg given orally every 24 hours for 6 weeks.
