Treatment of Tinea Barbae

First-Line Treatment

• The British Journal of Dermatology recommends terbinafine as the first-line treatment for tinea barbae caused by Trichophyton species at a dose of 250 mg daily for 2-4 weeks for adults weighing >40 kg 1
• Terbinafine is fungicidal and shows higher efficacy against Trichophyton species compared to other antifungals 1
• Dosing for terbinafine based on weight is as follows:

Alternative Treatment Options

• Griseofulvin is an alternative option, particularly if the infection is caused by Microsporum species, though this is less common in tinea barbae 1
• Itraconazole 100 mg daily for 2-4 weeks can be used as a second-line treatment if terbinafine is ineffective or contraindicated 1

Management of Treatment Failure

• Consider the following factors in treatment failure: lack of compliance, suboptimal absorption of drug, relative insensitivity of the organism, and reinfection 1
• If there has been no clinical improvement after initial therapy, switch to second-line therapy 1
• For resistant cases, consider increasing the duration of treatment 2

Prevention of Recurrence and Transmission

• Screen and treat family members if infection is caused by anthropophilic species 2
• Clean contaminated personal items with disinfectant 2
• Avoid sharing personal items and skin-to-skin contact with infected individuals 2

Treatment Duration and Follow-up

• In cases of clinical improvement but ongoing positive mycology, continue current therapy for a further 2-4 weeks 1, 3
• Follow-up should include both clinical and mycological assessment until clearance is documented 2
