Help relieve your female dog’s urinary incontinence with Incurin. Tablets are FDA approved and available by prescription from your veterinarian.

What is Incurin (Estriol)? This is oral medication available in tablet form to help manage your female spayed dog’s urinary leakage(incontinence).

What are the benefits of Incurin?
Treats your dog’s urinary incontinence when it caused by hormonal changes that can result after ovariohysterectomy (spay).
Oral tablets are easy to give generally well-tolerated.

Formulated for: female , spayed dogs only.

How is this medication given? Incurin is given by mouth once daily. The dose is not based on your dog’s body weight. Always follow your veterinarian’s precise directions. The recommended dose is to give 1 tablet (1mg) per day for 7-14 days. If this dose is effective after this time period, try to reduce the dose to the minimum possible dose by trying ½ tablet/day, then ½ tablet on alternate days. If treatment is ineffective at the lower doses, go back to the minimum dose that is effective. If treatment at 1mg daily is ineffective, the dose may be increased to 2mg daily for 7 days as directed by your veterinarian.

How does this medication work? Incurin supplements female, spayed dogs with oestrogen. Replacing oestrogen will help to relieve your pet’s urinary incontinence when it is caused by low or absent oestrogen levels that occur as a result of the ovariohysterectomy (spay) surgery in female dogs.

What results can I expect? Your dog’s clinical symptoms should improve. He/she should stop leaking urine. Effectiveness is defined as no signs of incontinence for 7 consecutive days. An improvement will usually be noticed within a few days. Adjustment of the initial dose will often be necessary. Your veterinarian will help you to figure out the ideal dose of Incurin for your dog. Medication should be continued indefinitely if it is working.
