The vaginal flora normally contains "good" bacteria and fewer "undesirable" bacteria. When the vaginal pH is at its normal level (between 3.8 and 4.0), a healthy balance is achieved between all these bacteria that coexist to prevent infections. Bacterial Vaginosis occurs when this healthy balance between the "good" bacteria (Lactobacilli) and the "bad" bacteria (Gardnerella) becomes disrupted due to various external risk factors. When the number of "good", protective bacteria decreases, "bad" bacteria take over, leading to Bacterial Vaginosis infection. Prevegyne™ vaginal tablets treat Bacterial Vaginosis by acidifying the vaginal fluid to lower the pH to its physiological level and stimulate the growth of protective bacteria, and they prevent recurrence of Bacterial Vaginosis by ensuring a healthy and long-lasting balance of the vaginal flora. One of the benefits of Prevegyne™ specific formulation is that it rapidly neutralizes the abnormal odour typically caused by Bacterial Vaginosis.
