The term "hapten" does not belong in the list because it is not a complete antigen. Haptens are small molecules that can bind to antibodies, but they are unable to induce an immune response on their own.
That is a very good question again asked by the expert on this subject. In the first place you do not know the exact mechanism by which penicillin allergy occurs. It may be due to traces of bacterial proteins remaining in the preparation or may be mediated through hapten mechanism or either of them or very rarely both of them may be responsible for the allergic reaction of penicillin. When you prepare the amoxicillin from penicillin, the protein/proteins responsible for allergic reaction may be destroyed and you do not get the allergic reactions of amoxicillin so commonly. Nevertheless severe anaphylactic reacions with injectable ampicillin has been obsevered by the cotntributor, although very rarely as compared to penicillin. And injectable ampicillin should be better avoided in patients allergic to penicillin.
A hapten is a small molecule that can elicit an immune response only when conjugated with a large carrier such as a protein. Typical haptens include drugs, urushiol, quinone, steroids, etc. This is what I read on Creative Biolabs.

Because the molecule is too small to cross-link with immune-cells
fagan asked this at ysu? haha fail.
No; there is no penicillin in ibuprofen.
iv penicillin
What is the taxonomy of penicillin?
Penicillin does not have sulfur in it.
