How to treat bedbug bites in a person? - in detail
Bedbug bites typically appear as small, red, raised spots that may itch, swell, or develop a blister. Prompt care reduces discomfort and lowers the risk of secondary infection.
First, cleanse the affected area with mild soap and lukewarm water. Rinse thoroughly and pat dry with a clean towel. This removes potential contaminants and prepares the skin for further treatment.
Apply a topical antihistamine or corticosteroid cream to alleviate itching and inflammation. Options include:
- Over‑the‑counter hydrocortisone 1 % cream, applied 2–3 times daily.
- Antihistamine ointments containing diphenhydramine, applied as needed.
- Calamine lotion for a soothing, drying effect.
If oral relief is required, an antihistamine tablet such as cetirizine 10 mg or diphenhydramine 25 mg can be taken every 12 hours, respecting dosage limits and contraindications.
For persistent swelling or pain, a non‑steroidal anti‑inflammatory drug (NSAID) like ibuprofen 200 mg may be used every 6–8 hours, provided there are no contraindications.
Monitor the lesions for signs of infection: increasing redness, warmth, pus, or fever. Should any of these appear, seek medical attention promptly. A clinician may prescribe a short course of oral antibiotics if bacterial involvement is suspected.
To prevent further irritation, avoid scratching. Trim fingernails short and consider wearing light cotton gloves at night if compulsive scratching occurs.
In cases where the bite area becomes ulcerated or the individual experiences an allergic reaction (e.g., widespread hives, difficulty breathing), emergency care is required.
Finally, address the source of the infestation. Professional pest control, thorough laundering of bedding at 60 °C, and vacuuming of mattresses and furniture are essential steps to eliminate the insects and stop new bites from occurring.
