Why is my mother not getting relief from extremely itchy, reddish-black rashes on her hands and back, as well as an itchy head, after 10 days of using terbinafine, Ebast 20, Candid B soap, and levocetirizine, and what should we do next given her history of an underactive thyroid?
Since her symptoms haven't improved after ten days of using terbinafine, Ebast 20, levocetirizine, and Candid B soap, the underlying cause might not be fungal. Reddish-black rashes can sometimes point to eczema, an allergic reaction, or skin changes linked to her underactive thyroid. Please consult a dermatologist or her primary doctor soon. They can evaluate her thyroid status, accurately diagnose the rash, and adjust her treatment safely. In the meantime, keeping her skin moisturized with a plain emollient and avoiding hot water can help soothe the itching.
