Megacilin Injection is a combination of Piperacillin and Tazobactam, a broad-spectrum antibiotic used for the treatment of moderate to severe bacterial infections. Piperacillin is a penicillin-class antibiotic, while Tazobactam is a beta-lactamase inhibitor that enhances the effectiveness of Piperacillin against resistant bacteria.

This injectable formulation is commonly used in hospital settings for serious infections requiring strong antimicrobial therapy.
