The recommended single dose of the antibiotic metronidazole or tinidazole doesn’t always eliminate the trichomoniasis, or “trich” parasite, which causes the most common curable sexually transmitted disease (STD), say researchers at Tulane University School of Public Health and Tropical Medicine in New Orleans.
For the study, half of more than 600 women diagnosed with trichomoniasis received the usual single dose of metronidazole, and the other half were given a seven-day course of the antibiotic. According to the researchers, women who were treated for seven days were about 50 percent less likely to still have the infection than those given a single dose.
Each year, trichomoniasis affects about 3.7 million women in the United States, increasing the risk of having serious birth complications, like preterm delivery and low birth weight, and contracting HIV (human immunodeficiency virus). In most cases, trichomoniasis infection doesn’t cause symptoms.
