Systemic Treatment
Patients were started in systemic treatment on day one of FLE treatment. The oral dose of isotretinoin was 5 mg/day and tetracycline (Lymecycline) 300 mg/day. Tetracycline was preferred to doxycycline because of its less photosensitizing effect.69 The patients were prescribed to take retinoids regularly throughout the study. Tetracycline was stopped after 12 weeks while isotretinoin was continued until acceptable clearance was obtained for each case. 9 patients (5 males, 2 with IGA 4 and 3 with IGA 3 and 4 females with IGA 4) started isotretinoin 5 mg/day and 3 patients (2 males and 1 female both with IGA 3) tetracycline (Lymecycline) 300 mg/day (Table III). Finally, patients were prescribed a cleaning soap for greasy skin and a moisturizing gel for acneic skin with isomerate saccharide and nicotinamide and a lip balm for patients taking retinoids.
Patients were advised to avoid or minimize UV-exposure or use UVA and UVB high protection, especially during the summer period and for patients taking isotretinoin.
