Low risk of anaphylaxis to penicillin:
- nonspecific symptoms unlikely to be allergic: GI distress, headache, yeast vaginitis
- nonurticarial maculopapular (morbilliform) rash without involvement of mucous membranes, palms, or soles
- pruritis without rash
- family history of penicillin allergy but no personal history
- no recollection of allergic symptoms or treatment
