Wash bedbug bites with soap and water to prevent infection and keep itching at bay, according to the American Academy of Dermatology. A weak form of corticosteroid can reduce itching, and a stronger corticosteroid can be prescribed if necessary.
Bedbug bites tend to go away naturally on their own within two weeks, notes the American Academy of Dermatology. It is important to avoid scratching them, as scratching bedbug bites can cause an infection. A doctor or dermatologist may prescribe an antihistamine pill or liquid to reduce itching or an antiseptic to prevent an infection.
Consult a dermatologist if there are several bites, if the bites are infected, if there is an allergic reaction to the bites or if the bites blister, states the American Academy of Dermatology. Signs of an infection include tenderness and oozing pus. Signs of an allergic reaction include hives and swollen or red skin.
Bedbug bites usually occur in a diagonal zigzag pattern, notes the American Academy of Dermatology. The only way to stop the bites is to get rid of the bedbug infestation. The best way to treat bedbugs is to contact a pest control specialist, as foggers and bug sprays are not usually effective.
