Your elevated IgE level of 457 suggests an underlying allergic response. Hydroxyzine, the medication you are taking, provides only temporary relief. For safer, long-term management, daily use of second-generation, non-sedating antihistamines like levocetirizine, fexofenadine, or loratadine is often recommended under medical supervision. Keeping your skin well-hydrated with fragrance-free moisturizers also significantly reduces itching. To find a more permanent solution, it is highly recommended to consult a dermatologist or allergist. They can help identify specific allergy triggers through testing and tailor a long-term treatment plan. Please do not worry, as chronic itching is highly manageable with the right daily strategy.

Managing long-term allergic rhinitis is very common and highly treatable. For daily control and to reduce nasal inflammation, a generic corticosteroid nasal spray (such as fluticasone or mometasone) is highly effective. For quick relief of sneezing and itching, non-drowsy oral antihistamines (like cetirizine, loratadine, or fexofenadine) work well. Additionally, regular saline nasal rinses help clear allergens like dust and pollen. If your symptoms persist, montelukast, an oral medication, can also be beneficial. Please consult your local physician or allergist to tailor a specific treatment plan that works best for you.

It is completely understandable to feel concerned, but please try to remain calm. Since your antihistamines and antifungal treatment have not improved the rash after three days, and it continues to spread, you should consult your doctor promptly for a review. The current treatment may need adjustment, or the rash might have a different underlying cause. Avoid scratching, use cool compresses to soothe your skin, and stop applying any new skincare products. However, if you develop any severe symptoms like difficulty breathing, swelling of your face or lips, or dizziness, please seek emergency medical attention immediately.
