Trichomoniasis - Medications

Trichomoniasis (trich) is usually treated with a medicine called metronidazole. The cure rate in treating trich using metronidazole is 90% to 95%.5Tinidazole has been shown to be this useful too.

Medicine choices

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

What to think about

Trich during pregnancy raises the risk of premature rupture of membranes (PROM) and premature delivery. Treating the infection doesn't appear to reduce this risk.3 If you are pregnant and have trich, talk to your doctor about the pros and cons of treatment.

Metronidazole vaginal suppositories or creams aren't recommended, because oral metronidazole is much more effective. Vaginal medicines cure trich in less than 50% of cases.5

Metronidazole vaginal gel, which is used to treat bacterial vaginosis, is not recommended for treatment of trich.7
