From the Guidelines
For an infected mosquito bite, clean the area with mild soap and water, then apply an over-the-counter antibiotic ointment like Neosporin or Polysporin 2-3 times daily for 3-5 days, as recommended by general medical guidelines 1. Some key points to consider in the treatment of infected mosquito bites include:
- Cleaning the area with mild soap and water to prevent further infection
- Applying an over-the-counter antibiotic ointment to reduce the risk of infection
- Covering the area with a clean bandage if needed
- Taking acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) as directed for pain or swelling
- Applying a cold compress for 10-15 minutes several times daily to reduce inflammation
- Watching for signs of worsening infection, such as increasing redness, warmth, swelling, pus, red streaks extending from the bite, fever, or swollen lymph nodes, which require prompt medical attention as oral antibiotics may be necessary 1. It's also important to note that infections occur when bacteria, typically Staphylococcus or Streptococcus from your skin or the environment, enter the small wound created by scratching the bite, and that avoiding scratching future bites can help prevent infection 1. Additionally, considering using an antihistamine like diphenhydramine (Benadryl) or applying hydrocortisone cream to reduce itching may be helpful 1. However, the most recent and highest quality study, which is from 2014 1, provides the most relevant guidance for the treatment of infected mosquito bites.
From the Research
Infected Mosquito Bite Treatment
- The treatment for an infected mosquito bite can vary depending on the severity of the infection and the individual's overall health.
- According to a study published in 1985 2, topical antibiotics such as triple antibiotic ointment containing bacitracin, polysporin, and neomycin can be effective in preventing streptococcal pyoderma, a type of skin infection that can occur as a result of mosquito bites.
- In cases where the infection is more severe, oral antibiotics may be necessary, as seen in a study published in 2003 3 which found that spider bites can result in necrotizing soft tissue infections that require aggressive surgical debridement and treatment with intravenous antibiotics.
- For individuals who experience anaphylaxis as a result of mosquito bites, immunotherapy using whole body mosquito extracts may be a viable treatment option, as shown in a study published in 1995 4.
- Antihistamines such as cetirizine can also be effective in reducing the symptoms of mosquito bites, including wealing and pruritus, as seen in a study published in 1990 5.
- In addition to these treatments, it is also important to take preventative measures to avoid mosquito bites, such as using insect repellents containing DEET, as recommended in a study published in 1998 6.
Prevention of Mosquito Bites
- Using insect repellents containing DEET can provide protection against mosquito bites, with a study published in 1998 6 finding that DEET-based repellents can provide nearly 100% protection when used in combination with permethrin-treated clothing.
- Wearing protective clothing, such as long-sleeved shirts and pants, can also help to prevent mosquito bites.
- Avoiding areas where mosquitoes are common, such as near standing water, can also help to reduce the risk of being bitten.
