A rash all over the body can be caused by various factors such as allergic reactions, infections, or irritants. Since you have already given half a tablet of Alzero (levocetirizine), an antihistamine used to treat allergic reactions, it may help reduce itching and rash if allergy is the cause.

🩺 Possible Causes

• Allergic reaction to foods, medications, or environmental triggers
• Viral or bacterial infections
• Skin irritation from contact with substances like soaps or plants

🏥 What You Can Do Now

• Continue monitoring the rash for changes in size, color, or if it spreads rapidly
• Keep the skin clean and avoid scratching to prevent infection
• Use cool compresses to soothe itching if needed

⚠️ When to Seek Immediate Medical Care

• Rash is accompanied by difficulty breathing, swelling of face or lips, or high fever
• Rash develops blisters, pus, or severe pain
• Rash worsens despite antihistamine treatment or new symptoms appear

It is important to consult a pediatrician promptly to determine the exact cause and appropriate treatment for your son's rash.
