From the Guidelines
For bed bug rash treatment, over-the-counter corticosteroid creams like 1% hydrocortisone are most effective, applied 2-3 times daily for 3-7 days to reduce inflammation and itching. Oral antihistamines such as diphenhydramine (Benadryl) 25-50mg every 4-6 hours or cetirizine (Zyrtec) 10mg once daily can also help control itching 1. Antibiotics are not typically needed as bed bug bites are not bacterial infections, but if scratching leads to secondary infection (indicated by increasing redness, warmth, swelling, or pus), topical antibiotics like bacitracin or mupirocin may be applied 2-3 times daily, or oral antibiotics might be prescribed by a doctor 1. To prevent infection, keep the area clean with mild soap and water, avoid scratching, and apply calamine lotion for additional itch relief. Cold compresses can also reduce swelling and itching. These treatments work by reducing the body's inflammatory response to bed bug saliva, which contains proteins that trigger allergic reactions in many people. Most bed bug rashes resolve within 1-2 weeks with proper treatment.
Some key points to consider:
- Bed bug bites are not typically bacterial infections, so antibiotics are not usually necessary 1
- Over-the-counter corticosteroid creams and oral antihistamines can help reduce inflammation and itching 1
- Topical antibiotics like bacitracin or mupirocin may be used if secondary infection occurs 1
- Keeping the area clean and avoiding scratching can help prevent infection 1
- Calamine lotion and cold compresses can provide additional relief from itching and swelling 1
It's essential to note that the provided evidence does not directly address bed bug rash treatment, but rather skin and soft tissue infections in general. However, the principles of treatment for skin irritation and infection can be applied to bed bug rash treatment. According to the most recent and highest quality study available, the best approach is to use over-the-counter corticosteroid creams and oral antihistamines to reduce inflammation and itching, and to prevent infection by keeping the area clean and avoiding scratching 1.

From the Research
Treatment Options for Bed Bug Rash
- There is no specific antibiotic treatment for bed bug rash, as bed bugs do not transmit diseases to humans 3.
- Treatment for bed bug rash typically involves relieving symptoms such as itching and inflammation.
- Antihistamines and topical corticosteroids may be used to alleviate symptoms 4.
- In some cases, bed bug infestations may trigger allergic reactions, and treatment may involve antihistamines or other medications to manage these reactions 4.
Eradication of Bed Bugs
- The most effective way to treat bed bug rash is to eradicate the bed bugs themselves 5, 6, 3.
- This can be done through nonchemical means of control, such as washing and drying bedding and clothing, and using mattress encasements 3.
- Insecticides may also be used to control bed bug infestations, but their use should be judicious and carefully managed to avoid harming human health 3.
Diagnosis and Prevention
- Accurate diagnosis of bed bug infestations requires a thorough history and physical examination, including consideration of social drivers of health such as housing status and living environment 5.
- Prevention of bed bug infestations involves taking steps to reduce the risk of infestation, such as inspecting for signs of bed bugs when traveling and using mattress encasements 3.
