From the Guidelines
For a 1.5-year-old with mosquito bites on the face, treatment should focus on relieving itching and preventing infection. Apply a cold compress to the affected area for 10 minutes to reduce swelling and itching, as suggested by the 2024 American Heart Association and American Red Cross guidelines for first aid 1. Use children's diphenhydramine (Benadryl) liquid at 1.25 ml for a child weighing 20-24 pounds, following package instructions for proper dosing based on weight. A thin layer of 1% hydrocortisone cream can be applied to bites up to twice daily for 2-3 days. Calamine lotion is another option to soothe itching. Keep your child's fingernails short and clean to prevent scratching that could lead to infection. Dress them in light, loose clothing to minimize irritation. If signs of infection develop (increasing redness, warmth, swelling, or pus), or if the child develops a fever or widespread rash, contact your pediatrician immediately. These treatments work by reducing the histamine response that causes itching and inflammation after a mosquito bite. For prevention, use age-appropriate insect repellents containing 10% DEET or less, applying to your hands first then to the child's skin, avoiding eyes and mouth.
Some key points to consider:
- Cold compresses can help reduce local pain and swelling, as mentioned in the practice parameter update 2011 for stinging insect hypersensitivity 1.
- Oral antihistamines and oral analgesics can help reduce the pain or itching associated with cutaneous reactions.
- Many physicians use oral corticosteroids for large local reactions, although definitive proof of efficacy through controlled studies is lacking.
- Topical corticosteroids, such as 1% hydrocortisone cream, can be used to reduce inflammation and itching.
- Calamine lotion can be used to soothe itching and reduce the risk of scratching and infection.
It's essential to note that while these treatments can help alleviate symptoms, they may not completely eliminate the risk of infection or other complications. Therefore, it's crucial to monitor the child's condition closely and seek medical attention if any signs of infection or other concerns arise. Additionally, using age-appropriate insect repellents and taking preventive measures, such as dressing in protective clothing and avoiding peak mosquito hours, can help reduce the risk of future mosquito bites.
