Your current routine may be failing because Dosetil cream (desoximetasone), a strong topical steroid, can cause rebound flare-ups or worsen underlying fungal or bacterial issues when used long-term. The white spots and bumps suggest a complex skin condition that steroids alone cannot resolve. Additionally, stopping your antihistamine, levocetirizine (Xyzal), can allow itching and inflammation to flare up. Because recurring rashes require identifying specific triggers, please consult a dermatologist.

Since your symptoms have progressed despite using oral steroids (Zampred), antihistamines (Xyzal M, Alaspan), antibiotics (Agithral, Clindatime), and topical creams (Fucibet, Chitomesh SF), this may indeed be an adverse reaction, drug allergy, or contact dermatitis. Your most important next step is to stop applying the topical creams and consult a dermatologist or urologist immediately. They can safely assess the area, perhaps perform a skin biopsy or patch test, and find a gentle, targeted way to help you heal comfortably.

Since Xyzal can sometimes cause drowsiness, there are excellent, truly non-drowsy generic alternatives available. I highly recommend trying fexofenadine or loratadine. Both are very effective daily antihistamines that will help soothe your hives without making you feel sleepy. Please follow the package instructions closely. If your hives do not improve, or if you ever experience any swelling of your face or lips, or difficulty breathing, please seek immediate medical care.

Continuing levocetirizine (Xyzal) is excellent for controlling your hives; tracking and avoiding food triggers will also help. For the dark spots, gentle topical treatments like azelaic acid are safe for your skin and won't impact your kidney stones or uric acid levels. Since weight and high uric acid are connected, a balanced, low-purine diet can help manage both safely. Please consult a dermatologist and your primary care doctor to tailor this plan safely to your needs.

Since they have returned, a great next step is to consult an allergist or dermatologist for allergy testing, such as patch or skin prick tests, to identify your specific triggers. For long-term management, we often recommend starting daily oral antihistamines, such as cetirizine, a few weeks before your typical allergy season begins. Keeping your skin barrier strong with gentle, fragrance-free moisturizers is also key. Your doctor may also discuss non-steroidal topical creams for safe, long-term control.

Since Xyzal and Dazit are causing sleepiness, you might discuss switching to fexofenadine with your doctor, as it is generally considered the least sedating second-generation antihistamine. For your Winolap (olopatadine), ensure you apply gentle pressure to the inner corner of your eyes after using the drops to limit medicine absorption into your body. Additionally, managing exam stress, taking cool baths, and wearing loose cotton clothing can naturally soothe your hives. Please consult your doctor before making any changes so you can safely stay alert and comfortable.
