Abstract

Since the early trials of metronidazole (Flagyl - M & B)¹ in 1960 the recommended dosage for treating trichomoniasis has been 200 mg three times daily for 7 days, although good results have also been obtained with a 5-day course.² Apart from an occasional report to the contrary³ the standard course continues to give satisfactory results. Shorter courses of treatment would be of value for the many patients who do not take their drugs reliably and for the male consorts who should be treated, but who are commonly symptom-free and may see no reason to take the course. A possible disadvantage of a short course is that early reinfection from an infected consort is more likely unless the consort is treated at the same time.
