Hydrocortisonum, opinions and questions

Hello, for 2 weeks I have been getting a rash, red itchy blisters. There was an ambulance because my face was all swollen. They asked if I was taking zyrtec clatra and lime. I'm taking it, but no results. The rash occurs all over the body. Every day. It stings terribly. Can anything else help?

Hydrocortisonum sp 10mg tablets are taken by anyone and is it normal to have a rash, vomiting, lack of strength and itchy skin and flaking?

Good morning, for two weeks on the thigh I have some strange rash or something similar to this, at the beginning there was a pimple and Then it spread more and still does, I used only hydrocortidonum ointment but to no avail I will add photographs below

Hello, the dermatologist stated that I have contact dermatitis with irritation. Skin in the area of the labia slight erythema. No obvious signs of infection. Recommended hydrocortisone 0.5% 2x 5-7 days. Can I combine this ointment with clatra. If so, at what interval?
