What is Trichomonas?

Trichomonas vaginalis is an infection of the vagina or urethra, caused by the parasite trichomonas vaginalis.

Trichomonas is transmitted through unprotected sexual contact and is common in many places in the world, but rare in Denmark.

What are the symptoms of trichomonas?

The symptoms can be foamy, greenish-yellowish, foul-smelling discharge. There may also be itching and irritation in and outside the vagina, as well as burning when urinating.

Both men and women can be infected with trichomonas vaginalis, but men will rarely experience symptoms.

Complications of trichomonas

Infection with trichomonas during pregnancy can cause premature birth.

How is trichomonas detected?

The infection can be detected by examining secretions from the vagina under a microscope. Trichomonas can also be detected via a swab from the urethra.

How is the treatment done?

The infection is treated with an antibiotic called metronidazole.

Metronidazole can act like Antabuse (disulfram) and cause vomiting and discomfort when consumed simultaneously with alcohol, and alcohol must therefore not be consumed 3 days before, during and up to 3 days after treatment.

Possible side effects of treatment

In rare cases, nausea and mild stomach discomfort may occur during treatment with metronidazole tablets.
