Therapy
Once the doctor has made the correct diagnosis, it depends on the cause how the rash is treated with blisters.
- Chickenpox: Symptom treatment with cool, moist compresses against itching and paracetamol or ibuprofen against pain
- Shingles: cool, moist compresses, antivirals, pain relievers and ointments
- Blistering diseases: Drugs to suppress the immune system (e.g. cortisone)
- Burns: immediate cooling with tap water, nourishing ointments for regeneration
Diagnosis
A glance from an experienced general practitioner or dermatologist is often enough to make a diagnosis, as many skin rashes show typical patterns. The localization of the rash, the vaccination status and the accompanying symptoms also provide information about the probable cause of the rash. If a rash is not related to any disease or does not improve with therapy, a sample excision or punch biopsy (tissue sample) can be taken by the dermatologist.
