Ivermectin is a commonly used antiparasitic medication in horses, but its use in pregnant mares requires careful consideration. Generally, ivermectin is considered safe for use in pregnant mares when administered according to veterinary guidance. However, it’s crucial to consult a veterinarian before administering any medication to ensure the safety of both the mare and the developing foal.
