[Metronidazole therapy in rosacea (author's transl)].

Metronidazole was administered (500 mg daily the first month, 250 mg daily the second month and, in some cases, 250 mg every other day the following months) to 62 patients suffering from rosacea or perioral dermatitis. 90 p. 100 of them improved within 2 months and Metronidazole was particularly effective against papulo-pustules. Relapses after interruption of treatment seemed to be less frequent than with Tetracycline therapy. Side-effects (gastro-intestinal disturbances) occurred in few patients but long-term tolerance remains uncertain. So, the length of treatment was less than 6 months and the drug was not given to pregnant women.
