Metronidazole is used to treat trichomoniasis. All sexual partners should be treated. Anyone with trichomoniasis should also be checked for other STDs and treated appropriately.
Metronidazole can cause nausea, a bad taste in the mouth, and vaginal infection.
Metronidazole is highly effective against trichomoniasis. The individual should follow safer sex practices to avoid another infection.
Any new or worsening symptoms should be reported to the healthcare provider.
