We are in need of a cost-effective alternative to a specific veterinary prescription for a horse. The requirement is for a product that provides the same efficacy as a well-known medication, with a dosage of 20mg, totaling 40 tablets consumed daily over a 10-day course. The current option is proving to be quite expensive, which is prompting us to explore other viable solutions. Could you please provide information on any alternatives available that would meet these specifications? We are particularly interested in options that maintain the same therapeutic benefits while being more budget-friendly. Any details regarding pricing, availability, and potential substitutes would be greatly appreciated as we work to ensure our horse receives the proper care without the financial strain.
