Can ivermectin be used on pregnant mares?

Ivermectin is commonly used in equine medicine to treat various parasitic infections. However, when it comes to pregnant mares, the use of ivermectin requires careful consideration. While generally considered safe, it’s crucial to consult a veterinarian before administering any medication to pregnant mares to ensure the health of both the mare and the developing foal.

Is Ivermectin Safe for Pregnant Mares?

Ivermectin is often deemed safe for use in pregnant mares, but veterinary guidance is essential. The drug has been widely used in equine medicine for controlling parasites like strongyles and bots. However, the health status of the mare, the stage of pregnancy, and the specific parasite load must be evaluated to decide on the most appropriate treatment.

How Does Ivermectin Work?

Ivermectin works by paralyzing and killing parasites. It targets the nervous system of the parasites, effectively eliminating them from the horse’s body. This action makes it effective against a broad spectrum of parasites, including:

  • Strongyles
  • Ascarids
  • Bots

What Are the Benefits of Using Ivermectin?

Using ivermectin in equine care offers several benefits, especially in controlling parasite populations:

  • Broad-spectrum efficacy: Effective against many parasites
  • Ease of administration: Available in paste, liquid, and injectable forms
  • Long-lasting effects: Provides protection for several weeks

Are There Risks Involved?

While ivermectin is generally safe, there are potential risks, particularly when used improperly:

  • Overdose: Can lead to toxicity, though rare in horses
  • Resistance: Overuse may contribute to parasite resistance
  • Pregnancy considerations: Always consult a veterinarian for pregnant mares

When Should Ivermectin Be Administered to Pregnant Mares?

Timing and dosage are critical when administering ivermectin to pregnant mares. Typically, it is safe to use during most stages of pregnancy, but the exact timing should align with a deworming schedule advised by a veterinarian. This ensures the mare’s health and minimizes any risk to the foal.

What Are Alternatives to Ivermectin?

If ivermectin is not suitable, other deworming options are available. These alternatives should also be discussed with a veterinarian:

Alternative Parasites Targeted Safety in Pregnancy
Fenbendazole Strongyles, ascarids Generally safe
Pyrantel Strongyles, tapeworms Generally safe
Moxidectin Strongyles, bots Use with caution
