Since your itching has lasted three years, you may have chronic urticaria or contact dermatitis. While antihistamines like levocetirizine provide temporary relief, long-term management requires a targeted approach. I highly recommend seeing a dermatologist or allergist for a proper diagnosis. For long-term control, they may suggest: 1. Topical calcineurin inhibitors (like tacrolimus), which are steroid-free and safe for sensitive areas like the face and neck. 2. Biologic therapies (like omalizumab) if diagnosed with chronic hives. 3. Identifying triggers through allergy testing. Meanwhile, use gentle, fragrance-free moisturisers daily and avoid harsh soaps to soothe your skin barrier. Many highly effective, safe options exist to help you find lasting relief.
