In the past, traditional deworming programs didn’t consider each horse as an individual, as common practice was to deworm the entire barn on a fixed, regular schedule.However, over the past 10 years, studies have shown there is a growing concern regarding parasite resistance to dewormers.
“Technically, veterinarians are not supposed to dispense a compounded drug if there is a commercially available product already, such as phenylbutazone [bute],” Moore says.“If your vet felt that there was a therapeutic use for a combination product of bute and vitamin E, then that is a legitimate reason for compounding it.It is available as an injection or in granular form and does not require a prescription.If given incorrectly, it can carry a risk of injury or illness for the horse.“There ares health-derived issues including gastric and colon ulcers, as well as renal impairment.
Renal impairment is more prevalent in older horses that have developed issues with their kidney function or with equine athletes that perform strenuous exercise and divert blood flow from their kidneys.Phenylbutazone, or “bute,” is one of the most commonly administered prescription drugs in the non-steroidal anti-inflammatory drug (NSAID) family.When used properly, NSAIDs offer relief from pain and help in the reduction of inflammation and fever.In equine medicine, compounding is the manipulation of one drug outside its original, approved form to make a different dose for a specific patient, whether it’s mixing two drugs together or adding flavouring to a commercially available drug. Last July, Equine Canada issued a notice asking their members to use compounded drugs with caution citing that because these medications are not available as a licensed product, they may contain different concentrations compared to a licensed product. fit=350,525&ssl=1" class="alignright size-full wp-image-57430" src="https://i2com/nz/wp-content/uploads/2014/07/feed-dish_3882.jpg? resize=350,525" alt="feed-dish_3882" width="350" height="525" srcset="https://i0com/ After being injected with a compounded vitamin supplement that was incorrectly mixed, all 21 ponies collapsed and died.There have been several instances where the medication contained too little of an active ingredient, leaving it ineffective, or too much, which can result in death. “The biggest issue with compounded drugs is that many horse owners are not often aware of what it means,” Moore says.Chronic or repeated dehydration is also a risk factor for renal impairment.
