Generally, your immune system is supposed to fight off the bacteria that make you sick. But sometimes your body fights the medicine itself. That’s what happen when you have a penicillin allergy, which is an abnormal reaction of your immune system to the antibiotic drug penicillin. Penicillin is prescribed for treating various bacterial infections.

If you have penicillin allergy, you may experience:

  • Anaphylaxis
  • Fever
  • Hives
  • Itching
  • Itchy, watery eyes
  • Skin rash
  • Shortness of breath
  • Swelling
  • Runny nose
  • Wheezing

You may also experience side effects of penicillin when you take it with other medications, which are not an allergic reaction to the drug. Depending on the type of penicillin, common side effects may include mild nausea or diarrhea, headache, or vaginal itching.

I cannot take penicillin either, but this is not something that is uncommon with penicillin. It is an antibiotic. And there are plenty of antibiotics that the doctor can use to replace it in case you have another infection. So this will not affect taking certain meds. Just make sure you should always give this information to all your doctors.
hey me too! if im allergic to penicillin does that also mean im highly allergic to blue cheese as well? i've never had it because i was afraid of that sooo...???
If you are allergic to penicillin, you may not be allergic to eatables like blue cheese.You may try it and if you get an allergic reaction,take an anti-allergic tablet.But surely you will be allergic to all the derivatives of penicillin like ampicilline and amoxicilline.
be careful! im allergic to penicillin and the off brand amoxacillin, which i get red flushed out skin, i also get itchy skin much like the hives. i was perscribed amoxacillin for a tooth infection and i told the doc i was not sure if i was allergic to it, he told me to go ahead and take it and if i had any problems to just call him and he would give me something else.But like I said red flushed skin, so if you skin got itchy after having blue cheese you should definitely stop!
If you r a person that is VERY allergic to Penicillin then you d better no. But if your slightly allergic then it depends.
You should wear an Allergy ID bracelt, necklace, whatever. Carry something in your wallet/purse that also identifies your allergies. Because penicillin is found in a lot of drugs and everyone should be aware of your allergy in case of an emergency. I almost lost my mom a couple of years ago because she was allergic to HCTZ and no one knew. Now that we know, we aren't going to risk another chance of losing her.
Penicillin is one of the basic antibiotics. Many people around the world are allergic to Penicillin. Some people could have fatal allergic reactions after injection of Penicillin.

People who are positive in a Penicillin skin test can't get injection of Penicillin and may not be able to take it orally either.

There're many other antibiotics, being allergic to Penicillin doesn't affect your treatment much.
