Regumate but horse still in season???

[opinionuk]

My mare has recently been put on regumate by vets recommendation, for 20 days now her temperament has improved and she's changed into a friendly horse which is great, however she is still coming into season, I thought the whole idea was to stop her coming into season???

How long has she been.on it for ? I used to do 10 days on 10 days off, but she came into season. So vet suggested half dose all through summer. Worked a treat! I could adjust it a bit once I knew when she was worse or better ie tailed off gradually on autumn.
