Regumate 2,2 mg/ml 1000 ml

Regumate Equine is a clear, light yellow oily solution. Each ml of Regumate Equine contains 2.2 mg Altrenogest as the active substance.

In mares with significant follicular activity during the transitional period between seasonal anoestrus and the breeding season (follicles of at least 20-25mm present at the beginning of treatment):

  • Suppression/prevention of oestrus (usually after 1 to 3 days of treatment) during the prolonged oestrus periods occurring during this period.
  • Control of the time of initiation of oestrus (approximately 90% of mares show signs of oestrus within 5 days following the end of treatment) and synchronization of ovulation (60% of mares ovulate between days 11 and 14 following the end of treatment).


  • Do not use in mares where uterine infection has been diagnosed.
  • Do not use in males.
  • Do not use in mares which produce milk for human consumption.

Adverse reactions, such as uterine infections, are extremely rare.

Instructions for use

The recommended dosage is 0.044 mg altrenogest per kg bodyweight per day, for 10 consecutive days. Carefully withdraw the volume of product corresponding to the mare bodyweight (1 ml per 50 kg bodyweight) and administer this volume via oral route.

Remove the original cap and in its place screw on the luer lock cap. Keeping the bottle upright, screw the syringe onto the luer lock cap orifice, turn the bottle upside down, and carefully withdraw the solution from the bottle using the syringe. Turn the bottle right way up before detaching the syringe. Securely replace the small cap on the luer lock cap.

Each ml of Regumate Equine contains Altrenogest 2.20 mg as the active substance and Butylhydroxyanisole (E3210) 0.07mg, Butylhydroxytoluene (E321) 0.07mg, Sorbic acid (E200) 1.50mg, and Benzyl alcohol 10.00mg as excipients.
