Chlorothiazide is a diuretic similar in action to hydrochlorothiazide as an efflux transporter, but has low oral bioavailability[1].

It is used for treatment of calcium oxalate uroliths[2] and in low doses, for management of nephrogenic diabetes insipidus[3].

Recommended dose rate in dogs is 10 - 40 mg/kg given orally every 12 - 24 hours[4].
