Terbinafine 250 mg pp daily was administered to 21 patients affected by tinea unguium of the toenails. In 14 cases Trichophyton rubrum was the aetiological agent while Trichophyton mentagrophytes var. interdigitale affected the rest. The treatment was administered randomized during 12 or 24 weeks in two groups of 11 (group A) and 10 (group B) patients. The clinical and mycological response was evaluated at week 12, 24 and 48. Adverse events were registered during the therapeutic period. At week 24, 55.5% of patients from group A were cured, only one patient did not improve and cultures were positive. In group B 66.6% were cured and three were clinically improved but cultures were positive, in the last control after 48 weeks the results were similar except one patient of the group B who worsened of his nails lesions. Only one case of acute urticaria was noted, the symptoms disappeared after the withdrawal of terbinafine. Terbinafine per os is a safe and effective antifungal for the treatment of the tinea unguium of the toenails. A period of 12 weeks of administration is enough in most of cases but when T. rubrum is the aetiology relapse could be possible.
