Severe itching on your body can be very uncomfortable and may be due to allergies, skin conditions, or other causes. An antihistamine like cetirizine (found in Cetzine 10 mg tablets) is often used to relieve itching caused by allergic reactions.

• You can consider taking an antihistamine such as cetirizine, but only under a doctor's prescription and guidance.
• Avoid scratching the affected areas to prevent skin damage or infection.
• Keep your skin moisturized with gentle, fragrance-free lotions.
• Identify and avoid possible triggers like certain soaps, detergents, or foods.
• If itching is accompanied by swelling, difficulty breathing, or spreading rash, seek immediate medical attention.
