What is trichomoniasis?
Trichomoniasis is an infection of the vagina and penis. It
is a sexually transmitted disease that can be treated and
does not cause any serious permanent damage. However, if a
pregnant woman is infected and does not get treated, the
disease can cause premature delivery and low birth weight in
the baby.
How does it occur?
A tiny organism called Trichomonas vaginalis causes the
infection. Sexual partners not using condoms can spread
these organisms to each other during sex.
What are the symptoms?
Many women infected with Trichomonas do not have any
symptoms. When they do have symptoms, the most common ones
are:
- frothy, green or yellow, foul or strong smelling vaginal
discharge
- itching, redness, and soreness of the vagina
- burning when going to the bathroom
- pain during sex.
Men usually do not have symptoms. When they do, the most
common symptom is irritation at the tip of the penis.
How is it diagnosed?
Your health care provider will ask about your symptoms and
examine you. Your provider will get a sample of fluid from
the vagina or penis. The fluid will be examined under a
microscope or grown in a culture to see if Trichomonas is
there. Results of the culture may be available in 2 to 7
days.br />
Your health care provider may also test for other
infections.
How is it treated?
Trichomoniasis is treated with a medicine called Flagyl. If
you may be or are pregnant, tell your health care provider.
This medicine should not be used during the first 3 months
of pregnancy.
Do not drink any alcohol while you are taking Flagyl and for
2 days after you finish the medication. Drinking alcohol
while you are taking Flagyl may cause a severe nausea and
vomiting.
Flagyl may be taken with food to prevent nausea and vomiting
(possible side effects of the drug).
Your sexual partner(s) should also be treated.
How long will the effects last?
For most people, the symptoms disappear less than 1 week
after treatment.
How can I take care of myself?
- Tell everyone with whom you have had sex in the last 3
months about your infection. They must also be treated
with Flagyl, even if they have no symptoms. Do not have
sex until your symptoms are gone and both you and your
partner have finished your treatment.
- Because trichomonas is sexually transmitted, there are
ways that you can help prevent this infection. Use of
latex or polyurethane condoms are the only way to protect
against trichomoniasis. In addition, you are less likely
to get an STD if you have just one sexual partner.
When should I call my health care provider?
Call during office hours if:
- Your symptoms last more than 7 days.
- You have other questions or concerns.
