S. and Acne vulgaris (overview)
ManifestationThis section has been translated automatically.
Especially among adolescents and young adults; more pronounced among boys or men. With acne tarda courses up to the 4th decade of life and beyond.
Clinical featuresThis section has been translated automatically.
In the area of the seborrhoeic zones, especially on the face, shoulders and back, in the upper sternal region, disseminated follicular comedones, inflammatory red papules and papulo-pustules as well as larger nodules are found, which become denser towards the body axis (centrofacial, middle of the back). If the inflammation is extensive, ruptures of the nodules, painful, deep abscesses, cyst and fistula formation, and deep scarring when healed may occur.

External therapyThis section has been translated automatically.
- See below Acne vulgaris. Depending on the extent of the seborrhoea and the skin sensitivity, benzoyl peroxide 2.5-10% in a gel base (e.g. Akneroxid Gel, Aknefug oxid, Benzaknen, Cordes BPO, PanOxyl) or in a cream base (e.g. Klinoxid, PanOxyl) or suspension as minute therapy (e.g. Akneroxid-L, PanOxyl W).e.g. Akneroxid-L, PanOxyl W), initially 1 time/day, after habituation 2 times/day or azelaic acid 20% (Skinoren), initially 1 time/day, later 2 times/day or 0.05% isotretinoin (e.g. Isotrex cream/gel) 1 time in the evening or adapalene 0.1% (Differin gel/cream) 1 time in the evening. New topical retinoid since 2020: Trifarotene (Selgamis, Aklief) 1 time in the evening.
- If treatment is not successful enough, this basic therapy can then be supplemented by the morning application of a topical antibiotic. Established are clindamycin (Basocin) and erythromycin in alcohol, gel or ointment base (e.g. Aknemycin/Stiemycine Lsg., Aknemycin Ointment, Acne Cordes/Clinofug 2/4% Gel). Alternatively, tetracycline in ointment base (e.g., Imex Ointment). Alternatively nadifloxacin (Nadixa cream). Application in each case 2 times/day.
Internal therapyThis section has been translated automatically.
- S.u. Acne vulgaris. If there is no visible treatment success after 4-6 weeks of extended external therapy, internal antibiotics can be given additionally. Minocycline (Aknosan, Klinomycin) initial 2 times/day 50 mg p.o. Alternatively: Doxycycline (Supracycline) initial 2 times/day 100 mg p.o., later 1 time/day 100 mg p.o. Alternatively: Tetracycline (e.g. Tefilin, Tetracycline-Wolff) initial 1 g/day p.o., later 500-750 mg/day p.o.
- In women with severe seborrhoea and/or androgenisation also administration of antiandrogenic contraceptives (e.g. Clevia, Esticia, Diane 35, Neo-Eunomine).
Notice! Possible reduction of the anticonceptive effect with simultaneous administration of antibiotics!
