pIf you have a positive skin prick and subcutaneous test, and a negative blood test, can you still be allergic? This is for milk - a friend's son had positive skin tests for milk allergy and negative blood tests. The allergist said the blood test is the one to abide by.br /
So, he is on dairy. However, he is always constipated, has no appetite, weighs 28 pounds and is one month shy of his 3rd birthday, small, bony looking, has asthma, is on flovent, serevent, singulair, zyrtec, flonase and albuterol.br /
Thanks!br /
I know this is not peanut related, but since many of your PA kids are also MA, I thought I'd ask. I'm still on the waiting list for acceptance to the Yahoo group POFAK!br /

Sorry, but are you saying that the child is on all those drugs at the same time?

My dd has a posotive skin test to egg but the RAST was negative. I have never given her straight egg but she eats things with egg in them all the time with no problems. The closest she came to eating straight egg was in a sherbert my mom made where there were uncooked egg whites and she got 3 tiny little bumps around her lip. I will not give her straight egg because I think she may react to that with maybe hives. But, I don't want to find out!!!

Yes, he is on this drugs at the same time, give or take one or two.
I appreciate your advice - I have become very impressed with the knowledge on this board!

We need help from the parents dealing with asthma---is it normal to be on several asthma
drugs at the same time? Could over-medication be affecting his health?
It sounds like this boy has different problems than allergies. Has he been tested for celiac? "Celiac Disease is a medical condition in which the absorptive surface of the small intestine is damaged by a substance called gluten. This results in an inability of the body to absorb nutrients: protein, fat, carbohydrates, vitamins and minerals, which are necessary for good health. "

Well I am no expert w/ asthma to be sure, but can tell you our experience.
After my son's visit w/ the ped. allergist, he was prescribed many of those same drugs.
Singulair is a daily asthma controller. Asthma needs to be well-managed (under control) especially if he were to have an accidental peanut ingestion.
Flovent & Serevent were to be taken only when his asthma flared or at first sign of a cold to prevent an asthma flare up. My son's Dr. said: The Flovent is a steroid to help w/ inflammation and the Serevent is bronchiodialtor (like a long lasting albuterol)
Albuterol is used as a rescue med. for an asthma attack.
The zyrtec is a long lasting antihistamine to help w/ his eczema.
Can't help w/ the flonase as we have no experience w/ that.
Also, I remember my son's regular ped. saying that tests can be wrong, we go more by the child's history of reactions.

That may be the way your doctor has your child using these meds, but in general they are used on a daily basis to prevent asthma attacks, so it's perfectly reasonable for an asthmatic person to be using these inhalers (even along with Singulair) on a daily basis. I think people often go on Singulair, though, in hopes of weaning off the other inhalers.
Of the other meds the OP's child was on, (Zyrtec, Flonase and albuterol), the Zyrtec is an antihistamine, to prevent reactions ranging from asthma to itchy eyes to a stuffy nose to itching to whatever [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]. The Flonase is a nose spray to keep the nose from getting stuffy, especially during allergy season, and the albuterol, of course, is to deal with any asthma episodes that occur despite all the other drugs. :-)
So it makes sense to me that the OP's child was on all these meds simultaneously, although I do wonder if he's on them all just seasonally or all the time.

He was tested for wheat allergy and it was negative, so I guess that rules it out.
He does have pretty bad asthma, too. We were just wondering b/c of his lack of appetite, constipation, and low weight would be due to the fact that is IS allergic to milk, even though his RAST was negative. Those who have had kids with positive skin pricks and negative RASTs eliminate that product, or leave it in diet?
My apologies, also, to anyone bothered by the fact that this post is in the wrong place. I am a busy working mom of twins plus an older singleton. I just now had time to read the "rules" for posting on this board. I will try to put new topics in their proper place from now on!

Celiac is not a wheat allergy. It is a condition in the bowels. Nothing at all to do with the immune system only the digestive system.
If this child has not been tested for other medical conditions other than allergies, you might want to investigate with a pediatrician. You could try eliminating dairy but please talk to your doctor first. It sounds like the child is not getting many nutrients to begin with and you don't want to make it any harder on him.
