Metronidazole is the usual treatment. Alternatives include tinidazole. Both are administered orally (1,2).

  • metronidazole 400 mg twice a day for 5-7 days or 2 g as a single dose if compliance is a problem
    • or
  • tinidazole 2 g as a single dose

Note: Stat doses should be avoided if pregnant or breast feeding (1,2).

In pregnancy a dose of metronidazole 200mg tds for 7 days is a possible treatment regimen. The male partner should also be treated; especially if there is a recurrence. During treatment, a condom should be used during intercourse. It is advisable to treat an asymptomatic woman in whom trichomonas has been found, before it becomes an established infection.

Note that when one sexually transmitted disease is found, others frequently co-exist and should be looked for (Gonorrhoea often co-exists with trichomoniasis). GUM clinic review is recommended.

Alcohol abstinence is advised during the course of the treatment and at least for 2 days afterwards because of the possibility of a disulfiram-like reaction (1).

Current sexual partners of women diagnosed with TV should be offered a full sexual health screen and should be treated for TV irrespective of the results of their tests (3)

Recurrent TV is usually due to re-infection, but consideration should be given to the possibility of drug resistance (3)
