Treatment

The most common treatment for trichomoniasis, even for pregnant women, is to swallow one megadose of either metronidazole (Flagyl) or tinidazole (Tindamax). In some cases, your doctor might recommend a lower dose of metronidazole two times a day for seven days.

Both you and your partner need treatment. And you need to avoid sexual intercourse until the infection is cured, which takes about a week.

Don't drink alcohol for 24 hours after taking metronidazole or 72 hours after taking tinidazole, because it can cause severe nausea and vomiting.

Your doctor will likely want to retest you for trichomoniasis from two weeks to three months after treatment to be sure you haven't been reinfected.

Untreated, trichomoniasis can last for months to years.
