Treatments and drugs

By Mayo Clinic staff

The most common treatment for trichomoniasis, including if you're pregnant, is to swallow one megadose of either metronidazole (Flagyl) or tinidazole (Tindamax). Taking the medication by mouth is much more effective for trichomoniasis than inserting a cream or gel version of the medication into the vagina.

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

Side effects of the medication may include:

  • Nausea
  • Vomiting
  • Headache
  • Metallic taste
  • Dizziness

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