GWIC has received multiple enquiries this week regarding the use of various medications to control oestrus in female racing greyhounds.

Frequently used, permitted medications include:

• Noriday®
• Primolut®-N
• Orabolin® (currently in short supply)

If you have been prescribed an alternative treatment, please discuss the option carefully with your prescribing veterinarian to avoid an inadvertent positive swab.

Where ethyloestrenol/Orabolin® cannot be sourced, the only alternative for oestrus control in female racing greyhounds are products that ONLY contain norethisterone (e.g. Noriday®, Primolut®-N). Beware of alternative, single pills that combine norethisterone with other medications (such as oestrogen) - these can result in positive swab results. Always check the dosage with your prescribing veterinarian as strengths may vary between different brands of norethisterone.

If you require assistance with any recent prescriptions or wish to discuss suitable replacement treatments further, please contact our Veterinary Team vets@gwic.nsw.gov.au
