I have a question which is is there are test for a penecilin allergy?

The reason I ask is that my nephew's father and his (the father's) mother are both allergic to penecilin, now they are both a little out of touch with reality and NEITHER of them wear medic alert bracelets, and my sister was shocked to learn about this allergy after dating the guy for well over two years!!!

Anyway, since I have a drug allergy (benadryl) as soon as I heard about the allergy I told my sister once my nephew was born to ask a lot of questions to the doctors. They are telling her that there isn't a test to see if you're allergic, and she'll have to wait until the first tme he's given the medication and then you'll know, which terrifies me and my sister as well for obvious reasons!

My mother swears that I was tested for an allergy to penacilin when I was two years old after developed a rash which she feared it was a reaction to penaclin (it wasn't it turned out to be the beginning of a learning process about my sensative skin and changes to any soaps and detergents!).

So my question is has anyone else heard about such a test or can point me somewhere where there is more info so that I can give the info to my sister?

A little info on my nephew he is only six and a half months old so I'm not evens sure what can be done right now but any information would be nice. With any luck it won't be an issue for him for a while! Iif it does become one his doting antie will be on the medic alert website investing in the cutest medical alert braclet she can find for the boy!

Thanx for any help with in advance!!!

Hi Dustytiger,

It's great that you are so involved and concerned for your nephew. I know many of us with allergies wish our families were so concerned.

Just my opinion, I don't think penicillin allergy, or allergies in general, are familial Meaning that just because you are allergic to peanuts doesn't mean your child will also be allergic to peanuts. The child may have more of a tendency to allergies, but not the same specific allergy.

And with allergies to medications, it is usually due to repeated exposure to the drug, such as many courses of antibiotics during childhood. When I was a child, they gave you one shot of penicillin for strep throat. Didn't have to do a 10-day course of oral meds. But this caused many children to develop penicillin allergies over time, so this practice was discontinued.

Both skin and RAST testing are available for penicillin allergy, but it is probably not necessary for your nephew. These tests are only used if there is a question as to which med may have caused a reaction. And if he were to get, say, an ear infection and need meds., the reaction would not necessarily be immediately life-threatening. It usually starts with more minor problems, such as a rash. Your sister would be extra cautious, and could call the Pediatrician if this happened. Only with repeat exposure after the initial diagnosis of allergy, like in your brother-in-law's case, would penicillin be dangerous. You are definitely right to kindly suggest to him that he get a medic alert bracelet. (Most doctor's offices and pharmacies have the pamphlets.)

Allergies to meds run the range from intolerances to true allergies.

Hope this helps,
Daisy

that does help a lot, i know about enviornmental allergies more then druge allergies and such, so that's why i'm trying to get information, and that does help it's just a concern that i have because in my research of environmental allergies you are more likely to have allergies if you have family members with the same allergies, not always of course but it can happen

i'm glad that there are some tests out there if when he goes on antibodies the the first time if there is any kind of reaction to it the first time he has it, my sister a a five minute walk or two minute run for our doctor's office so if somethin were to happen it woudln't take long for her to get over there

oh i have tried to subtly hint at my brother in law that he needs one, as well as give him the catolgues that medic alert sends me with all their jewlery pointing out th ones that are manly, that look like sports watches but he just doesn't clue in. he's not overly health conscience and generally ignores doctors orders

he's an astmatic who won't take his meds, he has a history of sleep apnia but won't go on diet, heck there are probably other things that he has wrong that no one even knows about because he just won't admit it so it's an uphill battle that's for sure! with any luck my nephew will not take after my brother in law and find the happy medium between his doctor-phobic daddy and his hypocondric mommy who is at the doctor's so much that the staff generally call her name instead of mine when i go in!!

I would agree with Daisy - the little guy may run a higher risk than normal of having allergies (or allergic diseases like eczema and asthma), but it's not a given that he would have a penicillin allergy.

I just did a google and found this:

http://www.clevelandclinicmeded.com/dis ... llergy.htm

which was kind of interesting. Might be a bit of overkill for what you're looking for, but it does confirm that there is a skin and blood test for penicillin. Oh - and it does say

Quote:
Race, **, personal or family history of atopic disease, and allergy to other drugs do not appear to be predisposing factors.


(There's your medical reference, Daisy. :) )

However, if it were me, I would still mention the family tendency to allergies to any doctors prescribing antibiotics, just so that they know that there is a history of such allergies in the family. Just to be safe.

First I do have to agree with what Daisy posted. But I still won't allow my youngest son to have penicillin.

My father-in-law had anaphylactic reactions to penicillin. (He didn't use that word, but it's what he described.) He does not wear a medic-alert.

My husband's brother had a bad reaction to penicillin. Possibly his sister did as well (wasn't very clear in explaining it).

My two oldest son's had minor reactions the first and second time they were given penicillin. (Not my fault. Doctor had marked their file NO PENICILLIN and then prescirbed them penicillin. I didn't know what it was -- so many names for things.)

So, I refuse to allow my youngest to have penicillin. Allergist actually told me, there's probably no risk at all. But, with total avoidance - it means even less risk. :D

It does have a lot of names and variations which is what makes me so nervous. Luckily my mother is a PSW (personal support worker) and has a lot of medical training from that and her dabbles in nursing courses but struggling with the math and science parts (grrr) as well as she has taken a pharmacy tech corrospondence. So if my sister were ever in doubt my mother could help her out, and we all know that and generally when we get something we ask our mother what is and such.

Wow it's kind of scary that the pharmacy didn't realise there a problem with the drug they had given your son. I know when I was trying some new drugs and I was worried about interactions (cause i was seeing a specialist as well as my own doctor who were both giving me scripts) both doctors assured me that if they missed something the pharmacy's computers would red flag my file and I'd get a call saying I coudln't be on whatever.

My daughter had a skin test in May for amoxycillin. Not all allergists do it. First they did a scratch test to which she didn't react, then they injected a little just under her skin. When this was also negative, they sent us home with an oral challenge. I had to give her a few specks on a spoon for a few days, then increase the powder until she finished one whole capsule in 6 days. The seventh day, I gave her a whole capsule, with no adverse effect.

We weren't sure she was allergic because she developed a rash a few days after a 14 day course about 7 years ago, so we just said she was allergic after that. But then my husband had sinusitis back in November and developed a bad rash after 5 days on amoxycillin, and we found out soon after that my MIL is also allergic to amoxycillin. The allergist assured us however that it was not genetic, but part of me doesn't totally agree. And as the literature that accompanied the oral challenge says, even if the oral challenge is successful, you can always become allergic, so you always have to be careful.

I'm allergic to penicillin & ampicillin, but Alexander has had amoxicillin and been okay. I was nervous about him getting it, but he was in the Children's Hospital at the time, so I felt much safer! Thankfully it all worked out.

As for the testing, I believe both times they've tested it on me (at 9 and 21 years old), they've just injected some under the skin on my forearm.

Just thought I'd add my two cents! : )

all of this stuff is really interesting, and those are the kinds of things that i'm looking for so that when my sister and i get a chance to have a chat next i've got a lot of info for her, our doctor is usually pretty open to listening to our fears so...

now we just have to get from my brother in law and his mother what exactly their reaction is since that also effects what to do for my nephew my fear is that if it's not caught early for my nephew that he will also be resistant about doing something about his allergy just like his daddy!

thank you sooo much for the information there's quiet a lot and i agree that allergies not be "genetic" as with some diaseses (diabetes, alzimers, cancer) but having someone in the family (esp father, mother, grandparent) does statiscially increase your chances of developing allergies and it's something that my sister and esp my brother in law should keep an eye on!

I was just at the allergist's last week, and he told me that there is currently no test for penicillin, it won't be available for another year, year and a half. My son was told he was borderline a few years ago, and to be retested. But this is what Dr. Ham Pong told me, and then said to keep him away from penicillin in the meantime.

You can get tested for penicillin, perhaps your doctor just doesn't test. Ask your family doctor to refer you to an allergist who does.
