I'm sorry to hear that your severe itching at night has not improved with the use of Teczine Tablet (levocetirizine). This medication is an antihistamine commonly used to relieve allergy symptoms by blocking histamine, which causes itching and other allergic reactions. However, if your symptoms persist despite a week of treatment, it may indicate that the cause of your itching needs further evaluation.

Here are some steps you can consider:

• Revisit your doctor or a dermatologist: Persistent itching can have various causes such as eczema, infections, scabies, or other skin conditions that may require different treatments.
• Avoid irritants: Use mild, fragrance-free soaps and detergents, and avoid scratching to prevent skin damage.
• Maintain skin hydration: Apply moisturizers regularly, especially after bathing, to soothe dry skin.
• Note any other symptoms: If you experience rash, swelling, fever, or worsening symptoms, inform your doctor promptly.

Since your current medication has not resolved the issue, a specialist doctor like a dermatologist can provide a thorough examination and may recommend additional tests or alternative treatments.
