What is the best ointment for bed bug bites? - briefly
A 1 % hydrocortisone cream applied several times daily effectively reduces inflammation and itching from bed‑bug bites. For rapid soothing, a calamine or antihistamine ointment provides additional relief.
What is the best ointment for bed bug bites? - in detail
When treating bites from Cimex lectularius, select a topical product that reduces inflammation, eases itching, and promotes skin healing. Three categories dominate clinical recommendations:
-
Low‑strength corticosteroid creams (e.g., 1 % hydrocortisone). These suppress the local immune response, diminishing redness and swelling within hours. Apply a thin layer to the affected area up to three times daily; limit use to seven days to avoid skin thinning.
-
Topical antihistamines (e.g., diphenhydramine 1 % cream). Histamine blockade curtails pruritus, providing rapid relief. Use after washing the bite; reapply every 4–6 hours as needed. Avoid on broken skin to reduce irritation.
-
Local anesthetic ointments (e.g., 5 % lidocaine or 5 % benzocaine). They numb the site, interrupting the itch‑scratch cycle. Apply once, allowing 5–10 minutes for onset; repeat no more than three times per day.
Adjunctive options include calamine lotion, which forms a cooling film and absorbs exudate, and zinc‑oxide paste, which creates a protective barrier and supports tissue repair.
Application protocol
- Clean the bite with mild soap and lukewarm water; pat dry.
- Apply the chosen ointment in a pea‑sized amount, spreading evenly.
- Cover with a non‑adhesive dressing only if the bite is open or prone to scratching.
- Monitor for adverse reactions (e.g., increased redness, swelling, or rash). Discontinue use if symptoms worsen.
Safety considerations
- Children under two years should not receive corticosteroids without medical supervision.
- Persons with known allergies to lidocaine, benzocaine, or antihistamines must avoid those formulations.
- Persistent lesions exceeding 48 hours, signs of infection (pus, warmth, fever), or severe allergic responses require professional evaluation.
Conclusion
A 1 % hydrocortisone cream offers balanced anti‑inflammatory action for most bites, complemented by diphenhydramine for itch control or lidocaine for immediate numbing. Selecting the appropriate ointment depends on individual tolerance, severity of symptoms, and any contraindications.
