Are there specific dewormers that are more likely to cause colic?
When it comes to horse care, understanding the potential side effects of dewormers is crucial. Some dewormers can indeed lead to colic, especially if not used correctly. Recognizing which dewormers might cause colic and how to use them safely can help you maintain your horse’s health.
What Is Colic and How Do Dewormers Affect It?
Colic is a broad term for abdominal pain in horses, often related to digestive issues. Dewormers, or anthelmintics, are medications used to eliminate internal parasites, which can affect a horse’s digestive system. Certain dewormers might cause colic if there is a heavy parasite load, as the rapid die-off of parasites can lead to blockages or inflammation.
Which Dewormers Are More Likely to Cause Colic?
While most dewormers are safe when used appropriately, some have been associated with colic under specific circumstances:
- Ivermectin: Generally safe, but can cause colic if there is a high parasite load.
- Moxidectin: Effective against encysted small strongyles, but poses a higher risk if the horse is heavily infested.
- Pyrantel: Safe in standard doses, but using a double dose for tapeworms can lead to colic in sensitive horses.
Why Do Some Dewormers Cause Colic?
The risk of colic from dewormers often arises from:
- High Parasite Load: A sudden die-off can lead to blockages.
- Improper Dosing: Overdosing or underdosing can cause complications.
- Sensitivity: Some horses are more sensitive to certain medications.
How to Minimize the Risk of Colic from Dewormers
To reduce the risk of colic when deworming your horse, consider the following strategies:
- Consult a Veterinarian: Always seek professional advice before deworming, especially if your horse has a history of colic.
- Perform a Fecal Egg Count: This test helps determine the parasite load and the appropriate dewormer.
- Follow a Deworming Schedule: Stick to a strategic deworming plan tailored to your horse’s needs.
- Monitor Your Horse: After deworming, observe your horse for any signs of colic, such as pawing, rolling, or lack of appetite.
Practical Example: Deworming Schedule
A strategic deworming schedule might look like this:
- Spring: Use a broad-spectrum dewormer like ivermectin.
- Summer: Perform a fecal egg count and deworm if necessary.
- Fall: Use a dewormer effective against tapeworms, such as a double dose of pyrantel.
- Winter: Use moxidectin to target encysted small strongyles.

How often should I deworm my horse?
The frequency of deworming depends on factors like age, environment, and parasite load. Typically, horses are dewormed every 6-12 weeks, but a fecal egg count can help tailor a specific schedule.
What are the symptoms of colic in horses?
Symptoms of colic include pawing, rolling, sweating, lack of appetite, and changes in behavior. If you suspect colic, contact your veterinarian immediately.
