On May 24, 2011 the FDA approved a new strength of Zyclara which offers clinicians greater flexibility when treating patients with imiquimod therapy.  Zyclara 2.5% has been approved for actinic keratoses(AK). The 3.75% cream was approved in March of this year and has an additional indication for both genital and perianal warts.  The main advantage of the 2.5% concentration is efficacy of the product with better tolerability to the most common side effect of imiquimod agents, local skin reactions ^[1],[2]
