Colchicine is a naturopathic remedy used for treatment of canine vasculitis[1], cystitis[2], epidermolysis bullosa[3] and osteoarthritis.

This drug is a chemical inhibitor of cell cycle synchronization and an inhibitor of cell mitosis[4].

Side-effects include blood dyscrasias and myelofibrosis.

Approximately 20% of colchine is excreted unchanged by the kidneys, and should be avoided in dogs with chronic renal disease[5].

Recommended dose rate is 0.03 mg/kg orally once daily for 14 days.
