Is it dangerous to eat moldy bread if you have a penicillin allergy?

Is it dangerous to eat moldy bread if you have a penicillin allergy?

No: Most mold on bread is rhizopus, not penicillium, and would not cause a reaction in those with allergy to the drug penicillin. There have been a few penicillium molds producing penicillin found in some sausages and cheeses, but generally, there probably is not enough penicillin to cause a reaction, since this is almost never seen. The usda recommends that moldy breads be discarded for everyone.

What occurs if you ate bread mould and are allergic to penicillin?

What occurs if you ate bread mould and are allergic to penicillin?

Nothing serious: Penicillin currently in use as an antibiotic is synthetic and not related to the mold spores found on bread. The bread mold may not taste so good, but should not induce an allergic reaction if penicillin allergic. An allergist can test for penicillin drug allergy as 75% of people will lose this allergy after 15 years of avoidance.

If I'm allergic to penicillin and eat berries with mold, will I have a reaction?

There are many...: ...Many, many kinds of mold. You will have a reaction if you allergic to penicillin and you eat the type of mold that makes penicillin (penicillium). Penicillium species are found all over the world, and are sometimes involved in food spoilage, so there is a chance that mold growing on berries could be of the penicillium variety. I advise not eating moldy fruit.

Can you take cephalosporin if you are allergic to penicillin?

Can you take cephalosporin if you are allergic to penicillin?

Pcn & Cehalosporins: The conventional number is 10% of penicillin allergic people are also allergic to cephalosporins, however the data is weak since the patient reported incidence of penicillin allergy may only be 10% accurate. There are also 3 generations of cephalosporins and the "cross reactivity" may vary between them. There does seem to be a direct relationship between reaction severity and cross reactivity.

This may be an odd question, but I shall ask it in any case. Is there any evidence that people who are allergic to penicillin are more likely to have an allergy to some other medications? If so, what?

This may be an odd question, but I shall ask it in any case. Is there any evidence that people who are allergic to penicillin are more likely to have an allergy to some other medications? If so, what?

Possible: Some people who are allergic to penicillin can also react to a class of drug called cephalosporins. But this is rather unusual. The only way to know for sure is to try a drug sometime and see if you react to it. It also makes a difference how severe the reaction was to penicillin.
