Methotrexate: role of treatment in skin disease.

ABSTRACT

Methotrexate has been used for over half a century to treat a wide spectrum of skin conditions. It is a valuable steroid sparing agent, preventing protracted steroid courses and their undesirable side effects. While many alternative therapies exist and continue to emerge to treat these dermatologic conditions, the long history, affordability, and relative safety associated with methotrexate ensure its enduring utility. Further, ongoing research focusing on the pharmacogenetic properties of the drug may allow for more effective and targeted therapeutic strategies.
