Thank you for asking at HCM.
I went through your history and would like to make suggestions for you as follows:
1. It is possible that your triple antibiotic ointment
may be containing penicillin or an antibiotic which is related to penicillin.So that you may have reacted to that particular antibiotic.
2. I would like to know what type of reaction you have now to guide you further.
3. However, at present, I would suggest you to consult your doctor, inform him/her that you are allergic to penicillin and to show him/her your allergic reaction
so he/she could make further changes.
Hope above suggestions will be helpful to you.
Should you have any further query, please feel free to ask at HCM.
Wish you the best of the health ahead.
Thank you & Regards.
