Brief Answer:
Allergy test needed again

Detailed Answer:

Dear Nss, I have gone through your question and I can understand your concerns..

Unfortunately penicillin requires an allergy test before taking it each and every time.. This means that even if you had an allergy test to penicillin last year, you have to repeat it before taking penicillin now. it is more safe to take amoxicillin if that's okay with your doctor..

I hope I answered your question, feel free to ask further..
