Trichomoniasis: Care Instructions


Trichomoniasis is a sexually transmitted infection (STI) caused by a parasite. It's often called trich (say "trick"). You can get it by having sex with an infected partner. Trich may cause vaginal itching and a smelly discharge. But in many cases, there are no symptoms.

Trich needs to be treated so that you don't spread it to others. Both you and your sex partner(s) should be treated at the same time so you don't infect each other again.

If you're pregnant, your doctor will talk with you about treatment. Trich may cause problems with pregnancy. You could pass it to your baby during a vaginal delivery. But this is rare.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Take your antibiotics as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.
  • Do not have sex while you are being treated. If your doctor gave you a single dose of antibiotics, do not have sex until one week after both you and your partner or partners have been treated.
  • Tell your sex partner or partners that they will also need to be tested and treated.
  • Use a cold water compress or cool baths to relieve itching.

How can you prevent it?

Here are some ways to help prevent STIs.

  • Limit your sex partners. Sex with one partner who has sex only with you can reduce your risk of getting an STI.
  • Talk with your partner or partners about STIs before you have sex. Find out if they are at risk for an STI. Remember that it's possible to have an STI and not know it.
  • Wait to have sex with new partners until you've each been tested.
  • Don't have sex if you have symptoms of an infection or if you are being treated for an STI.
  • Use a condom every time you have sex. Condoms are the only form of birth control that also helps prevent STIs.
  • Don't share sex toys. But if you do share them, use a condom and clean the sex toys between each use.

Vaccines are available for some STIs, such as HPV. Ask your doctor for more information.

When should you call for help?

Call your doctor or nurse advice line now or seek immediate medical care if:

  • You have unusual vaginal bleeding.
  • You have a fever.
  • You have new discharge from the vagina or penis.
  • You have pelvic pain.

Watch closely for changes in your health, and be sure to contact your doctor or nurse advice line if:

  • You do not get better as expected.
  • You have any new symptoms or your symptoms get worse.
