What is the treatment for Noseeum bites?

Treatment for Noseeum Bites

For noseeum bites, the most effective treatment is topical hydrocortisone to relieve itching, with oral antihistamines potentially helping with sleep but having limited efficacy for daytime itch relief. 1, 2

Understanding Noseeum Bites

• Noseeum bites (from tiny biting midges) typically present as pruritic weals and delayed papules, similar to mosquito bite reactions 2
• Reactions result from sensitization to the insect saliva injected during feeding 2
• Symptoms usually include localized itching, redness, and small raised bumps 2

First-Line Treatment Options

Topical Treatments

• Hydrocortisone cream/ointment is FDA-approved for temporarily relieving itching associated with insect bites 1
• Apply topical hydrocortisone to affected areas to reduce inflammation and itching 1
• Cool compresses may provide symptomatic relief of itching, though evidence is limited 3

Oral Medications

• Oral antihistamines may help with sleep at night but have questionable efficacy for daytime itching 3
• One observational study with 89 participants did not find statistically significant reduction in symptoms with oral antihistamines 3

Treatment Algorithm

1. Initial management:

   • Clean the affected area with soap and water 3
   • Apply cool compresses to reduce inflammation 3

2. Pharmacological treatment:

   • Apply topical hydrocortisone (available over-the-counter) to affected areas 2-4 times daily 1
   • Consider oral antihistamines primarily for nighttime use if itching interferes with sleep 3

3. When to seek medical attention:

   • If symptoms worsen or show signs of secondary infection (increasing redness, warmth, swelling, pain) 3
   • If systemic symptoms develop (fever, extensive swelling, difficulty breathing) 3

Special Considerations

• Low-potency corticosteroids (like over-the-counter hydrocortisone) may have limited efficacy compared to higher-potency prescription corticosteroids 3
• For severe reactions, prescription-strength topical corticosteroids may be more effective 3
• Avoid scratching to prevent secondary bacterial infection 3

Prevention Strategies

• Use insect repellents containing DEET or picaridin when in areas where noseeums are common 2
• Wear long-sleeved shirts and pants when outdoors during peak activity times (dawn and dusk) 2
• Consider using fine mesh screens on windows and doors as noseeums can pass through standard screens 2
