General therapyThis section has been translated automatically.
External therapyThis section has been translated automatically.
- Careful phototherapy cycles with UV rays, especially UVB, and possibly also UVA1, should be observed during therapy breaks. Alternatively outpatient balneo-phototherapy with UVB or PUVA therapy (as systemic PUVA therapy or as PUVA bath therapy).
- Dermatological climate therapy (maritime climate), which generally leads to a significant improvement.
- Nursing external measures. Oily O/W lotions or saline or urea-containing creams and ointments(e.g. basodexan, nubral, calmuride).
- In case of distinct itching creams or lotions containing glucocorticoids. Sparing use of cleaning agents such as syndets or soaps. Instead, use hydrophilic body oils as washing substitutes (e.g. ready-to-use preparations that are generally used as oil baths such as oil bath cordes, Balneum Hermal oil bath, Linola fat oil bath).
