Are rashes, vomiting, lack of strength, itching and peeling of the skin a cause for concern during the treatment with Hydrocortisonum SF?

Thank you for sharing your case. According to the Summary of Product Characteristics of Hydrocortisonum -SF, erythema, rash and inflammation of the skin are listed as potentially occurring adverse reactions. However, I do not find any information in the medical literature on vomiting and weakness. If you are concerned about the effects of the medicine, it is best to talk to your doctor, who is familiar with your health condition in detail. If you do not have the opportunity to consult your doctor, you can use the teleconsultation here:

Please remember that side effects of medications should be reported to your doctor or individually. By reporting side effects, you help other patients, including your relatives, who may also need the same medication in the future. This step also allows us to gather more information on the safety of medicinal products and to keep their data up to date. I encourage you to report an adverse reaction if you haven't already done so:
