Animax is available as an ointment in 15ml tubes. Each ml of ointment contains 100,000 units Nystatin, neomycin sulfate equivalent to 2.5mg of neomycin, 2,500 units thiostrepton and 1mg triamcinolone acetonide. Prior to use the affected area should be cleaned. Animax is for use topically on the skin.
