Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Vaginitis is the broad term which include variety of infection including bacteria, parasite, fungus etc. The infection you have mentioned here is bacterial or coccbacilili. So this type of vaginitis is caused by the bacteria. Sone times the infections are very resistant to the drug prescribed so changing of drugs is necessary. In your case norfloxacin and metronidazole combination is necessary please take it under your doctors guidance. Please maintian good local hygiene this is very important in treating infection as taking the antibiotics. Avoid sex till you are cured with the infection. Or you can use the condom to prevent transmission of the infection. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
