Answer

Intralesional corticosteroid therapy is usually recommended for alopecia areata with less than 50% involvement. Administration is as follows:

  • Injections are administered intradermally using a 3-mL syringe and a 30-gauge needle

  • Triamcinolone acetonide (Kenalog) is used most commonly; concentrations vary from 2.5-10 mg/mL

  • The lowest concentration is used on the face

  • A concentration of 5 mg/mL is usually sufficient on the scalp

  • Less than 0.1 mL is injected per site, and injections are spread out to cover the affected areas (approximately 1 cm between injection sites)

  • Injections are administered every 4-6 weeks
