Legend (hyaluronic acid) typically lasts 4 to 6 weeks in horses.
Legend is a hyaluronic acid injectable used to treat joint inflammation and support cartilage health in horses. After injection, its effects generally persist for about one month, though this can vary depending on the horse's condition, activity level, and joint health. Some horses may benefit from repeat treatments every 4 to 6 weeks, while others might need less frequent administration. Veterinarians often tailor dosing schedules based on individual response and the severity of joint issues.
Duration of Legend effects by administration route
| Administration Method | Typical Duration | Notes |
|---|---|---|
| Intra-articular (joint injection) | 4-6 weeks | Most common; localized effect |
| Intravenous | 4-6 weeks | Systemic distribution |
| Combination with other therapies | Variable | May extend or enhance effects |
