Sexually Transmitted Diseases : Trichomoniasis (trik-o-mon-i-a-sis)

Trichomoniasis is a very common infection of the vagina. Some women may notice an increase in vaginal discharge with a foul odor and a change in colour. Many women and men have no symptoms.

By direct contact, usually sexual, with an infected person.

Trichomoniasis is rarely dangerous but it can be very uncomfortable. In women, it can cause vaginal discharge, itching and pain when passing urine. Men often have no symptoms, but a few may notice a burning feeling when passing urine or after sex. This should be treated right away.

Usually with a drug called metronidazole which comes as a pill, a suppository or vaginal cream. The pills should not be taken in early pregnancy or while breastfeeding. Tell the doctor if you are pregnant, or think you may be pregnant.

Finish your treatment and don't drink alcohol until two days after the pills are finished. Alcohol reacts with metronidazole pills and will make you very sick. Metronidazole can also cause nausea. Take your pills with meals to help protect against this.

Wear cotton underwear and loose clothing. This will keep the area dry and speed up healing. Use cold compresses or soak in a tub to relieve the itching.
