Patient Delivered Partner Therapy for Trichomoniasis

Urgent and Private Information About Your Health

Your sexual partner has recently been treated for Trichomoniasis. Trichomoniasis is a sexually transmitted infection (STI), caused by a single cell protozoan. If symptoms do occur, they usually appear within 1 week after being infected, but can take up to 6 months to appear.

For some people, symptoms may go away and then return later. Many people, particularly men, will have no symptoms. It is important to know that Trichomoniasis can be easily treated and cured with an antiprotozoal medication.

You may have been infected with Trichomoniasis.

It is important that you get treated even if you have no symptoms.

Trichomoniasis can increase the risk of acquiring and transmitting HIV in both men and women. Not treating Trichomoniasis during pregnancy can increase the risk of preterm labour and premature delivery.

Make an appointment with your health care provider as soon as possible if you experience:

  • Penile discharge
  • Burning when peeing or after sex
  • Pain or redness at the tip of the penis
  • Vaginal itching
  • Pain during sex or when peeing
  • Foul smelling grey, yellow or greenish vaginal discharge

To protect your health, it is recommended that you visit your health care provider and take an antiprotozoal medication called Metronidazole (Flagyl) as soon as possible. If you are unable to see a health care provider right away, you may visit any of our confidential clinics for FREE testing and treatment.
