(Merck) Incurin Tablets are indicated for the control of estrogen-responsive urinary incontinence in spayed female dogs. Each Incurin Tablet contains 1 mg of estriol. The dosage of Incurin is not dependent upon body weight. All dogs should receive an initial dose of 2 mg (2 tablets) orally once per day for a minimum of 14 days. After urinary incontinence is controlled, the lowest effective daily dose should be determined, depending upon the response of the individual dog.
