It sounds uncomfortable to have an allergic rash after flea or tick bites, and managing it promptly is important to reduce symptoms and prevent complications.

🩺 Immediate Steps to Take

• Gently clean the affected skin with mild soap and water to reduce irritation and risk of infection.
• Avoid scratching the rash to prevent worsening or secondary infection.
• Applying a cool compress can help soothe itching and inflammation.

💊 Medication Options

• Antihistamines like cetirizine (found in products such as Avil NU 10 mg Tablet) can help relieve itching and allergic symptoms. However, these should be taken only after consulting a doctor to ensure safety and correct dosage.
• Topical anti-itch creams or calamine lotion may provide additional relief.

⚠️ When to Seek Medical Help

• If the rash spreads rapidly, is accompanied by swelling of the face or difficulty breathing, seek emergency care immediately.
• If you develop fever, pus, or increased pain at the bite sites, consult a doctor promptly as this may indicate infection.
• Persistent or worsening symptoms despite initial treatment also warrant specialist evaluation.

It is best to consult a dermatologist or an allergist who can assess your condition and recommend appropriate treatment tailored to your situation.
