OvaMed® is indicated for the suppression of estrus in mares. Suppresion of estrus allows for a predictable occurrence of estrus following drug withdrawal.

OvaMed® Activity


PregnantHorse sm

  • Daily use of a synthetic progesterone can help maintain pregnancy.
  • In some cases, OvaMed® (altrenogest) Solution 0.22% produces a progestational effect in mares, interrupting the cycle of hormonal activity and preventing estrus.
  • In some cases, OvaMed® helps maintain pregnancy once a mare has already been bred.
  • Some mares have low natural progesterone during pregnancy, which can lead to loss of pregnancy.
