Trichomoniasis

Medications

Trichomoniasis (trich) is usually treated with a medicine called metronidazole. The cure rate in treating trich using metronidazole is 90% to 95%.⁷

Medication Choices

Antiprotozoals, such as metronidazole, are medicines that kill the tiny parasite that causes trich.

What To Think About

Metronidazole vaginal suppositories or creams are not recommended because oral metronidazole is much more effective. Vaginal medicines are not effective in treating trich in areas other than the vagina and cervix. Vaginal medicines cure trich in less than 50% of cases.

Metronidazole vaginal gel, which is used to treat bacterial vaginosis, is not recommended for treatment of trich.¹⁰
