If you’re going to medicate your horse, you should know what you’re giving him. Competitive equestrians in particular should be aware of which drugs are listed as banned substances or controlled medication.
Horse Medication Terms

Controlled Medication has the potential to affect performance and/or be a welfare risk to the horse.
