Deworming a horse is an essential part of equine care, but it’s important to be aware of the potential side effects. While most horses tolerate deworming well, some may experience mild to severe reactions. Understanding these side effects can help you better manage your horse’s health and wellbeing.
What Are the Common Side Effects of Deworming a Horse?
Deworming medications, or anthelmintics, are designed to eliminate parasites in horses. However, they can sometimes cause side effects, which may include:
- Mild colic: Some horses may experience mild abdominal discomfort after deworming. This is usually temporary and resolves on its own.
- Diarrhea: A change in stool consistency can occur, but it typically subsides within a day or two.
- Loss of appetite: Some horses may temporarily eat less following treatment.
- Lethargy: A decrease in energy levels can happen, especially if the horse is dealing with a heavy parasite load.
How to Minimize Side Effects of Deworming?
To reduce the risk of side effects, consider the following strategies:
- Rotate Dewormers: Use different classes of dewormers to prevent resistance and reduce adverse reactions.
- Proper Dosage: Ensure the correct dosage based on your horse’s weight to avoid overdose or underdose.
- Monitor Health: Keep a close eye on your horse after deworming for any signs of distress or unusual behavior.
- Consult a Veterinarian: Before deworming, discuss your horse’s health and deworming history with a vet.
What to Do If Side Effects Occur?
If your horse exhibits side effects after deworming, here are some steps to take:
- Observe: Monitor your horse closely for any worsening symptoms.
- Provide Supportive Care: Ensure access to fresh water and a comfortable environment.
- Consult a Vet: If symptoms persist or worsen, contact your veterinarian for advice.
Why Are Anthelmintics Necessary for Horses?
Anthelmintics are crucial for maintaining a horse’s health by controlling internal parasites. These parasites can cause significant health issues, such as:
- Weight Loss: Parasites can lead to poor nutrient absorption and weight loss.
- Colic: Heavy infestations can cause abdominal pain and colic.
- Poor Coat Condition: A dull coat can indicate a parasite problem.
- Anemia: Blood-sucking parasites can lead to anemia and weakness.
How Often Should Horses Be Dewormed?
The frequency of deworming depends on several factors, including age, environment, and parasite load. Here are some general guidelines:
- Foals: Start deworming at 2-3 months old and continue every 2-3 months until one year of age.
- Adult Horses: Typically deworm 2-4 times a year, depending on pasture management and fecal egg counts.
- High-Risk Horses: Horses in high-risk environments may require more frequent deworming.

What Are the Signs of Worms in Horses?
Horses with worms may show signs such as weight loss, dull coat, colic, diarrhea, and poor performance. Regular fecal egg counts can help identify worm burdens.

Yes, deworming can sometimes cause colic, especially if the horse has a high parasite load. The sudden death of parasites can lead to intestinal blockages.
Is It Safe to Deworm a Pregnant Mare?
Yes, but it is crucial to use dewormers that are safe for pregnant mares. Consult your veterinarian for the best options during pregnancy.
How Long After Deworming Can I Ride My Horse?
You can usually ride your horse the same day after deworming, but if your horse shows any side effects, it might be best to wait until they feel better.
What Is the Best Deworming Schedule for Horses?
The best deworming schedule depends on your horse’s individual needs and risk factors. Work with your vet to develop a tailored plan based on fecal egg counts.
Conclusion
Deworming is a vital aspect of horse care, helping to prevent health issues related to parasites. By understanding the potential side effects and taking steps to minimize them, you can ensure your horse remains healthy and comfortable.
