Horse Medications & Health Conditions
Equine medicine spans a broad range of conditions, from acute emergencies like colic and laminitis to chronic management of gastric ulcers and joint disease. Horses are hindgut fermenters with a one-way digestive tract — they cannot vomit — which makes gastrointestinal conditions particularly dangerous. Their large body size requires precise weight-based dosing, and many medications are available in paste, granule, or injectable formulations designed specifically for equine use. Understanding how these medications work helps horse owners provide timely first aid and make informed decisions alongside their equine veterinarian.
Common Conditions in Horses
The following conditions are among the most frequently treated in equine practice. Many require prompt veterinary attention and ongoing management.
- Colic (Abdominal Pain)
