Medications for trichomoniasis include vaginal suppositories and oral medications. Metronidazole or tinidazole, which are mainly used to treat anaerobic infections, such as metronidazole suppositories, tinidazole suppositories, or compounded metronidazole suppositories, are effective in treating trichomoniasis when inserted into the vagina. In addition, oral metronidazole or tinidazole tablets can also treat trichomoniasis. Since both of these medications may cause gastrointestinal reactions, resulting in nausea and vomiting, it is recommended that they be taken only after meals. To treat Trichomonas vaginitis, it is important to stop taking the medication and go to the hospital for 3 days after the symptoms have disappeared in order to find out if the trichomonas has been completely invisible under the microscope, i.e., if it has been clinically cured. In addition, it is recommended to stop the medication only if 3 consecutive tests are negative.
