Medications like Isolor (loratadine) and Teczine (levocetirizine) aren't bringing relief. Since there is no rash, the itching is likely not an allergic reaction, which explains why these antihistamines haven't helped. Itching on the lower legs and body without a rash can be caused by simple dry skin, circulation issues, or sometimes underlying conditions related to your thyroid, kidneys, or liver. Please be reassured that this is common. I highly recommend consulting your doctor for simple blood tests to identify the root cause and get you the right relief.

Since your desonide (Desowan) lotion and levocetirizine (Teczine) are not providing relief, it is important to have your skin re-evaluated. For severe itching and blisters, a doctor may recommend stronger prescription topical corticosteroids, or oral medications to calm the system. Keeping the wounds clean and applying protective ointments like petroleum jelly can support skin healing and prevent infection. Please consult your dermatologist soon so they can examine the blisters and tailor a safer, more effective treatment plan for you.

Since daily antihistamines have not helped after several months, the cause may not be allergic. It is very important for them to consult a healthcare provider or dermatologist. Persistent lower body itching can stem from non-allergic issues like dry skin, circulation changes, nerve irritation, or localized skin conditions that require targeted prescription treatments rather than allergy pills. In the meantime, they can find some relief by applying a gentle, fragrance-free moisturizer and wearing loose, breathable clothing. Please reassure them that a doctor can help find the right solution.

Taking Teczine Tablet (Levocetirizine) and Ketasma Tablet (Ketotifen) frequently is generally considered safe under medical supervision, but needing them every two days suggests that your allergy triggers are not well controlled. You should consult your doctor or an allergist to identify the underlying cause and to ensure that these antihistamine medications are the most appropriate long-term treatment for you.

Currently, there is no permanent cure for allergies to prawns, crabs, and eggs in adults. The most effective long-term strategy is strict avoidance of these trigger foods. Always read food labels carefully and inform restaurant staff about your allergies. While you can continue using levocetirizine (Teczine) for mild symptoms like itchy skin patches, it is highly recommended to consult an allergist. They can discuss personalized management plans and evaluate if you need to carry an emergency epinephrine auto-injector for accidental, severe exposures.

Since standard antihistamines and nasal sprays haven't brought relief, you are an excellent candidate for allergen immunotherapy (allergy shots or sublingual drops), which helps desensitize your immune system to dust. First, I recommend consulting an allergist for diagnostic testing, such as a skin prick test or specific IgE blood test, to confirm your triggers. We can also evaluate you for nasal anatomical issues.
