What should be applied to bedbug and tick bites? - in detail

When a bite from a bed‑bug or a tick causes irritation, the primary goal is to reduce inflammation, prevent infection, and alleviate itching.

Immediate care

• Clean the area with mild soap and lukewarm water; gentle cleansing removes saliva residues and lowers bacterial load.
• Pat dry with a clean towel; avoid rubbing, which can worsen skin trauma.

Topical agents

1. Antihistamine creams (e.g., diphenhydramine 1 % or levocetirizine ointment).

   • Mechanism: blocks histamine receptors, decreasing pruritus.
   • Application: thin layer 2–3 times daily for up to 48 h.

2. Corticosteroid ointments (hydrocortisone 1 % or clobetasol 0.05 % for severe reactions).

   • Mechanism: suppresses local immune response, reducing erythema and swelling.
   • Application: thin film once or twice daily; limit use of potent steroids to ≤7 days to avoid skin atrophy.

3. Calamine or zinc‑oxide paste.

   • Provides a cooling effect and creates a protective barrier.
   • Apply 3–4 times daily until itching subsides.

4. Antiseptic solutions (povidone‑iodine 10 % or chlorhexidine 0.5 %).

   • Prevents secondary bacterial infection, especially if the bite is scratched open.
   • Apply once after cleaning; reapply if the wound re‑exposes.

Oral medications (if needed)

• Antihistamines (cetirizine 10 mg, loratadine 10 mg).

  • Indicated for widespread itching or systemic allergic response.
  • Dosage: one tablet daily for up to 5 days.

• Analgesics (acetaminophen 500 mg or ibuprofen 200 mg).

  • Relieve pain and reduce mild inflammation.
  • Follow standard dosing intervals.

Special considerations for tick bites

• Preserve the attached tick if removal is incomplete; use fine‑tipped tweezers to grasp close to the skin, pull upward with steady pressure, and disinfect the bite site.
• Assess for signs of tick‑borne disease (fever, rash, joint pain) within 2–4 weeks; seek medical evaluation promptly.
• In regions where Lyme disease is endemic, a single dose of doxycycline 200 mg may be prescribed prophylactically within 72 hours of removal, according to local guidelines.

Follow‑up

• Monitor the lesion for increasing redness, swelling, pus, or fever; these indicate infection and require professional medical treatment.
• If itching persists beyond 48 hours despite topical therapy, consider a short course of a stronger corticosteroid or referral to a dermatologist.

Applying the described cleansing steps, appropriate topical preparations, and, when necessary, oral agents provides comprehensive management of bites from bed‑bugs and ticks, minimizing discomfort and preventing complications.
