256. Beating Trichomoniasis


Trichomoniasis is caused by a protozoan. In females, when symptoms are present, they include vaginal itching and burning, a yellow, green, or gray vaginal discharge with odor, and burning or pain when urinating. In males, symptoms include mild itching and irritation of the penis, pain during intercourse, discomfort when urinating, and a discharge from the foreskin (in uncircumcised men). Men who have trichomoniasis usually don’t experience any symptoms, however, and may unknowingly infect their sexual partners.


Trichomoniasis is diagnosed by examining a drop of vaginal fluid or penile discharge under a microscope or by growing a culture.



If you’re being treated for trichomoniasis, follow these simple guidelines.

  1. Take medication as prescribed. The medication metronidazole (brand name Flagyl) is usually taken orally. (If you’re a female, don’t take this drug during the first three months of pregnancy.)

  2. Avoid drinking alcohol for 24 hours before or after taking the metronidazole. The combination causes vomiting, dizziness, and headaches.

  3. Women should douche with a solution of diluted providine iodine or a mild vinegar-and-water solution. (Don’t use as a substitute for metronidazole, however.) Ask your doctor what proportions he or she recommends, how often you should douche, and for how long.

  4. To soothe irritated skin around the penis or vagina, wash the genital area with mild, unscented soap and water at least once a day.


If you have trichomoniasis, your partner should be treated simultaneously. Otherwise, you’ll continue to re-infect each other.
