Psoriasis - Topical Medications

Topical Medications


Topical medications are those applied only to the surface of the body. They come in the following forms:

  • Creams
  • Foams
  • Gels
  • Lotions
  • Occlusive tapes
  • Ointments
  • Shampoos
  • Solutions
  • Sprays

In general, topical treatments are the first line for mild-to-moderate psoriasis, but they may also be used, alone or in combination, with more powerful treatments for moderate-to-severe cases. Topical medicines rarely clear up symptoms completely, however.

Topical Corticosteroids

Topical corticosteroids are the mainstay of psoriasis treatment in the United States. These drugs work for most patients because they:

  • Decrease inflammation
  • Block cell production
  • Relieve itching

Corticosteroids are available in a wide range of strengths, and are generally given as follows:

  • Less potent drugs are used for mild-to-moderate psoriasis.
  • Stronger drugs are reserved for more severe disease.

Topical steroids are often rated by how strong or potent they are:

  • Low potency (some are available over-the-counter)
  • Low-to-medium potency
  • Medium- to upper-mid potency
  • High potency
  • Very high potency
