Many veterinarians advise rotating different deworming “chemical classes” during different times of the year. There are three classes of dewormers available today: macrocyclic lactone, pyrimidine and benzimidazole. All of these contain several drugs within them. Additionally, there is a drug called praziquantel that doesn’t fall into any of the above classes. It was introduced a few years ago to treat tapeworms and is typically combined with a drug from the macrocyclic lactone class.
The downloadable chart provides a breakdown of the many equine dewormers on the market today. Each product is broken down by chemical class, drug (active ingredient) and manufacturer. Keep this chart handy when talking to your veterinarian about your horse’s deworming program.
