Hello,
The most consistent results may be seen with minocycline. Other modalities include keratolytics; intramuscular, oral, and topical forms of vitamin A; sodium thiosulphate; ammoniated mercury; oral contraceptives; oral and topical retinoids; thyroid extract; ultraviolet light; propylene glycol; antibiotics; antimycotics; and calcipotriene. There have been successful treatments with Azithromycin( Zithromax) and this has been published in many journals.
