Trichomonas infection

Trichomonas infection is a sexually transmitted infection (STI). Caused by the Trichomonas vaginalis organism, it is also called trichomoniasis.

Many people do not have any symptoms with this infection. Women may notice an abnormal discharge and this may have an offensive smell. It is easily treated with antibiotic tablets called metronidazole. It is important not to drink alcohol for at least 24 hours after taking these tablets because this could make you very sick.

Using a condom during sex is the best way to protect yourself from getting or passing on this infection.
