Control of Oestrus (Heat)

Why has my veterinarian prescribed this medicine?

Several products are available for the prevention or postponement of oestrus (heat, seasons) in female dogs.

Hormonal control of oestrus is not recommended before the first season, in dogs with a history of vaginal discharge, false pregnancy, or irregular heat periods.

It is important that your pet should have a normal oestrus every 18 to 24 months. It is often difficult to predict when your pet will come into oestrus after the medication is stopped. Continual hormonal control of oestrus may cause side effects in your pet. If your pet is not intended for breeding, think about having your pet spayed (sterilised, neutered).
