Hi kendal122 -
is it Suprax ? A third generation oral cephalosporin antibiotic which is a beta-lactame antibiotic like penicillin has been sold in the States under this name since about 2004 or so;
if you are allergic to penicillin I could immagine that you are at high risk with the Suprax too. I recommend asking your doc (or even your pharmacist !? - sometimes I have the feeling my pharmacist is even more cautious than any doc I have seen so far....). Greetings to you, dorit.
ps: the rocephin belongs into the same category as far as I know; did you take that w/o allergy? would be interesting to know. I have this allergy problems too, it is really a challenge to check which may work w/o causing additional chaos.
