Fishy odor down there is usually due to the phenomenon of bacterial vaginosis. Anti-anaerobic drugs are used to treat bacterial vaginosis, mainly metronidazole, tinidazole and clindamycin.
Bacterial vaginosis is due to the decrease of lactobacilli in the vagina and the increase of anaerobic bacteria such as Gardnerella, resulting in endogenous mixed infections. Clinical features are thin, fishy-smelling vaginal discharge that is markedly increased. It is necessary to go to the hospital for a leukorrhea test to confirm the diagnosis.
For patients with bacterial vaginosis, the drugs of choice are metronidazole and tinidazole. Accompanied by bacterial infections need to be accompanied by cephalosporin, levofloxacin drugs. For the accompanying vulvovaginal pseudomycosis, it is necessary to add fluconazole drug treatment.
The first choice is to go to the hospital to get a clear diagnosis of the fishy smell down there, and then standardize the treatment after the diagnosis is confirmed.
