Indications for use
The treatment of hormone-dependent urinary incontinence due to sphincter mechanism incompetence in ovariohysterectomised bitches.

Adverse Reactions
Oestrogenic effects such as swollen vulva, swollen mammary glands and/or attractiveness to males and vomiting have been observed at the highest recommended dose of 2 mg per dog. The incidence is about 5-9 %. These effects are reversible after lowering the dose.

Use during pregnancy or lactation
Do not use this product during pregnancy or lactation. See also section “Contraindications”.
Interactions
None known.
Amounts to be administered and administration route
For oral administration.
A relationship between final effective dose and body weight has not been established and therefore the dose has to be determined for each dog on an individual basis.
The following dosing schedule is advised: start treatment with 1 tablet (1 mg estriol) every day. If treatment is successful, lower the dose to half a tablet a day. If treatment is not successful, increase the dose to 2 tablets a day to be given in one dose. Some dogs do not need daily treatment; treatment every other day may be tried, once the effective daily dose has been established.
The minimum dose given should not be less than 0.5 mg per dog per day. Ensure the dose used to achieve the therapeutic effect is as low as possible. Do not use more than 2 tablets per dog per day. If no response to treatment is obtained the diagnosis should be reconsidered in order to investigate other causes for the incontinence such as neurological disorders, bladder neoplasia, etc.
Animals should be re-examined every 6 months during treatment.
Overdose
In case of overdose typical oestrogen effects may occur. These effects are reversible after lowering the dose.
Withdrawal periods
Not applicable.
