Questions & Answers

Side Effects & Adverse Reactions

Do not use in horses intended for human consumption.

NSAIDs should not be used concurrently with TILDREN. Concurrent use of NSAIDs with TILDREN may increase the risk of renal toxicity and acute renal failure. Acute renal failure has been reported in horses concurrently administered NSAIDs and TILDREN within a 48 hour period. Additionally, horses concurrently administered TILDREN and NSAIDs in field studies demonstrated a statistically significant increase in serum blood urea nitrogen (BUN) and creatinine concentrations. These elevations were not always associated with clinical signs of renal dysfunction. Therefore, appropriate wash-out periods should be observed between NSAID and TILDREN administration, and BUN and creatinine should be monitored. If treatment for discomfort is required after TILDREN administration, a non-NSAID treatment should be used.
