Metronidazole is an antibiotic used to treat various bacterial and parasitic infections, including certain sexually transmitted diseases (STDs). It is commonly prescribed for the treatment of trichomoniasis, a sexually transmitted protozoan infection caused by Trichomonas vaginalis. Metronidazole is generally efficient in eliminating T. vaginalis infection and has a low risk of serious side effects. It is also used to treat bacterial vaginosis, an infection caused by an overgrowth of bacteria in the vagina. Metronidazole works by stopping the growth of bacteria and is not effective against viral infections. It is important to take metronidazole as prescribed and to avoid alcohol while taking the medication, as it can cause more severe side effects. If metronidazole is unsuitable, alternative treatments may be recommended by a healthcare specialist
