  • Initially, use dithranol only in low concentrations and increase the concentration very slowly (s.a. psoriasis vulgaris). Accompanying daily brine baths and tar baths are also possible (e.g. Balneum Hermal with tar). If necessary, use in combination with UVB. Increase UV doses very carefully. Avoid Dermatitis solaris under all circumstances.
  • Alternative: Short-term external application of glucocorticoids, especially in case of fresh attacks. Pustules disappear after hours or days. After stopping the pustular flush, change to the classic external therapy scheme. Caution! Avoid irritating external agents!

Notice! The push activity is usually limited in time. Therefore the focus of the therapy has to be put on external measures!

Internal therapy

Systemic therapy according to psoriasis vulgaris. In addition to retinoids, fumaric acid esters or methotrexate have also proved successful. In case of resistance to therapy, a combination of methotrexate and fumaric acid esters would be possible under strict control of laboratory values and immune status.
