Dog - Aglepristone

Why has my veterinary surgeon prescribed this medicine?

Aglepristone is used for pregnancy termination (abortion) in bitches. It can be given up to 45 days after mating.

A partial abortion may occur in 5% of bitches. Your veterinary surgeon may need to see your pet 10 days after treatment and about a month after mating to check that the medication has worked and that pregnancy has been terminated.

Continual hormonal control of pregnancy and seasons may cause side effects in your pet. If your bitch is not intended for breeding, think about having her spayed (sterilised).

How does this medicine work?

Aglepristone blocks the action of the hormone progesterone, which is needed for pregnancy to continue.

How do I give this medication?

• Your veterinary surgeon will administer this medicine to your pet by injection

Potential side effects

• Side effects include temporary pain and swelling at the injection site.
• In bitches treated after 20 days of pregnancy, signs of parturition (giving birth) such as loss of appetite, fœtal expulsion, and swelling of the mammary glands may be seen at the time of abortion.
