It's probably a good Idea if you can wear metal. I can't wear jewelry my self. I am sure you can get on inscribed with both.

Meant to say how do i get medical bracelet I'm allergic to penicillin

If you’re looking for the right wording for your medical alert bracelet, it could say:
Allergic to Penicillin | SLE Lupus Patient
or Penicillin Allergy | SLE Lupus

Niranjana thanks for finding my answer useful🌹

I got my medical bracelet thru Amazon. Turned out very nice!
