Bed bug bites are treated using either antihistamines or corticosteroids for allergic reactions and antibiotics for potential bacterial infections, reports the American Academy of Dermatology. Washing with soap and water is an effective at-home remedy to reduce the chance of infection and itching from the bites.
Anti-allergy medication is commonly used to treat the swelling and itchiness, such as antihistamines or corticosteroids, reports the American Academy of Dermatology. In the case of severe allergic reactions, epinephrine may be administered. Severe skin infections require prescription antibiotics, but mild infections may only need a topical antiseptic skin wash. Such antiseptic washes may be recommended even when no infection is present to prevent any possible infections. Itchy bites are treated with liquid forms of prescription antihistamines, and at-home treatment includes corticosteroids.
Bed bug bites are characterized by a zigzag pattern of three to five itchy and reddened bites, adds the American Academy of Dermatology. These bites are commonly mistaken for mosquito or spider bites or a skin rash such as chickenpox, as bed bugs are rarely actually seen. If raised, itchy or oozing lesions are seen on the skin, a dermatologist should be consulted to determine the best way to treat the bites.
