How Is Trichomoniasis Treated?

The usual treatment for trichomoniasis is a very large oral dose of either tinidazole or metronidazole, both of which usually destroy the organisms responsible for the condition, Mayo Clinic says. The treatment can take up to a week to cure the disease fully, and patients should avoid sexual activity during this time. If a person requires treatment for trichomoniasis, doctors should treat any recent sexual partners as well.

Trichomoniasis is a parasitic infection that transmits during sexual activity, explains Mayo Clinic. Condoms reduce the risk of infection, but only abstention from sexual activity fully prevents it. Pregnant women with trichomoniasis may be at higher risk of giving birth prematurely. They are also at a higher risk of having a baby with low birth weight and may pass the infection on to the infant during birth.

Infection by the trichomoniasis parasite often causes no symptoms early, and in men it often never causes symptoms, Mayo Clinic says. In women, it can cause symptoms that include genital redness, pain with urination, pain with sexual intercourse, itching and burning. It can also cause a large amount of vaginal discharge, which can have a foul smell and be gray, yellow, green or white. When men have symptoms, they include burning during urination, discharge from the penis and irritation inside the penis.
