If someone is allergic to penicillin, are dermal filler safe to use?

Penicillin allergic patients can receive dermal fillers. There is no cross reactivity between penicillin and dermal fillers (hyaluronic acid, Radiesse, Sculptra). I have safely injected many patients with penicillin allergy. 

Most commonly used dermal filler Is Hyarulonic acid. though uncommon,late or recurrent inflammatory reactions can occur with this filler,however no known cross reaction with penicillin.

There is no issue with getting fillers if you have an allergy to penicillin. I have safely injected many people with penicillin allergies and have experienced no issues. "This answer has been solicited without seeing this patient and
