Zerogin Mouth Wash contains Chlorhexidine Gluconate 0.2% w/v, a potent antiseptic agent widely used for oral hygiene management. It is indicated for the prevention and treatment of gingivitis, periodontitis, and other inflammatory conditions of the oral cavity caused by bacterial infections. Chlorhexidine exerts its effect by disrupting the bacterial cell membrane, leading to cell death and a significant reduction in oral microbial load. Zerogin Mouth Wash is effective in controlling plaque formation and reducing oral malodor. It is commonly recommended as an adjunct to mechanical oral hygiene measures, particularly in patients with compromised oral health, post-surgical oral care, or those unable to perform adequate brushing and flossing. The product should be used as directed, typically twice daily after brushing, by rinsing the mouth with 10-15 ml for 30 seconds before expectorating. Prolonged use may cause tooth staining, altered taste sensation, and mucosal irritation; therefore, it is advised to limit use to the prescribed duration. Patients should avoid swallowing the solution and refrain from eating or drinking for 30 minutes post-rinse to maximize efficacy. Zerogin Mouth Wash offers a clinically proven approach to maintaining oral health and preventing bacterial complications.
