One of the best medicines that a doctor can prescribe to women who has bacterial vaginosis or BV is Zidoval. Zidoval vaginal gel contains the active ingredient metronidazole, which is a type of medicine called an antibiotic. Metronidazole is used to treat infections caused by bacteria and other micro-organisms called protozoa. Metronidazole works by entering bacterial and protozoal cells and interfering with their genetic material (DNA). It damages the DNA and also prevents the bacteria and protozoa from forming new DNA. This ultimately results in metronidazole killing the micro-organisms, which clears up the infection. Metronidazole kills a wide variety of bacteria that are known collectively as anaerobic bacteria. This means that they do not need oxygen to grow and multiply. Metronidazole gel is inserted into the vagina using an applicator to treat an infection called bacterial vaginosis. This is one of the best BV treatment but if you go for the natural way, you find the best of all natural bacterial vaginosis cures in this book guide called “Bacterial Vaginosis Gone Forever”.
