General therapyThis section has been translated automatically.
First, experiment with bland-free Lotio alba, ethanolic zinc oxide shaking mixture rp. 292, emulsions or gels. Active-ingredient-free cooling gels temporarily relieve itching rp. 039 . Cool showers, cool packs or moist compresses, e.g. with 0.9% NaCL solution, also have a soothing effect. If not sufficient, apply tannin 3-5% in lotio alba or external agents containing menthol or polidocanol (e.g. rp. 158 , rp. 200 , rp. 197 , Optiderm). The next step is glucocorticoid-containing emulsions (e.g. hydrogals, rp. 123 ) or 0.5% hydrocortisone cream (119). Furthermore, narrow band spectrum UVB was successfully applied.
