If allergy: A bed bug bite usually does not produce many symptoms, other than a mild local reaction. If you happen to be allergic to bug saliva, you may develop a welt at the site. If there is marked itching and a swelling at the site of the bite, you may take an over the counter antihistaminic, however, the side effects of medication may be more than those of the bug bite.
