Food Dye Allergy
I want to go get a blood test for allergies. Will this assess for all types of allergens? Will it tell if I'm allergic to food dyes?
Uncertain: Every single test needs be interpreted with the history and physical findings in context. Food dye allergy. other than to red carmine dye, is very rare if non-existent although it was in vogue over 40 years ago. ...Read more
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
Can a high positive ANA cause allergies? I never had allergy symptoms and now I react to so many things (food, medication, contrast dye, pollen, dust)
Hi I was wondering if I may have an allergy to rye (i'm allergic to rye grass) or gluten (not allergic to wheat or corn though) or dextrin or food coloring dyes that are artificial , since I was eating cheez-its and starburst last night and noticed my thr
Beware that allergy: is simply a label for behavioral response. Pretense is that someone else (Doc, etc.) really understands what is happening when actually just repeating the clients complaints//descriptions of behavior(s), using different words/diagnostic-labels, while promoting theories to justify low-level theories aimed at justifying what is being promoted/sold. Best don't miss bigger issues & internal controls. ...Read more
My daughter has a skin irritation/rash around her face when she eats certain food not sure what it is ava age 3, healthy
no known allergies so far
immunizations up to date?
Thinking it might be red dye #40?
Rash: This could simply be a basic irritant dermatitis due to little ones getting as much food on their face as they get in their mouth. And the food can irritate the skin. Also, kids will lick around the mouth, causing irritation. See the pediatrician for evaluation or a dermatologist. ...Read moreSee 1 more doctor answer
Can environmental allergies (food, pollen, dust mites, contrast dye, penicillin) cause a high positive ANA?
I have seen this: While the +ANA is suggestive of SLE there can be other causes - other connective tissue disease, autoimmune thyroid disease, auto immune hepatitis to name some. I have seen a lot of people with + ANAs who only have as another problem a history of allergic reactions and I am convinced that thee allergic reactions can cause a + ANA. Everyone can have very low titters (amount) of ANA. ...Read more
Patch testing: Quite a number of hair dyes are notorious allergens. If you read the small print on the dye , it warns of reactions. If you develop a rash and/or severe itching on your neck, upper back and/or your forehead and eyelids initially a week after dyeing your hair and with time the interval getting shorter, odds are significant. For diagnosis, see an allergist/immunologist for patch testing. ...Read more
Patch Test: To test for allergy to hair dye, a small patch containing the hair dye chemical is placed on the skin and held in place by tape for 48 to 72 hours. After removal, the doctor will look for a local reaction where the hair dye contacted the skin to diagnose allergy to the dye (phenylenediamine). ...Read more
Can be a challenge: Allergic reactions to hair dye and other hair hair chemicals (perms) can lead to skin reaction on the scalp called dermatitis. These products may also lead to skin reaction on the eyelids. Another scalp condition is seborrheic dermatitis (cradle cap in infants). A dermatologist or allergist would be a good resource to sort out the cause of the rash. Allergy patch testing may be helpful. ...Read more
Avoidance: There is no treatment for contact allergy other than avoidance and oral steroids. Because of side effects, long-term or repeated doses of steroids is not a good idea. If you've developed a contact allergy to a hair dye, the only reasonable thing to do is stop using it. Patch testing by an allergist can help you figure out which dyes you should avoid. ...Read more
Steroids: I think you need immediate attention, this is a serious allergy and can cause loss of hair and patchy hair if you do not treat it properly. Go see a doctor immediately. ...Read more
Unrelated: There is a common misunderstanding that one can be allergic to iodine yet this is incompatible with life -our thyroid hormone production depends on it. You are allergic to the muscle protein in shellfish and not to the iodine. The contrast dye reaction is from the molecular structure of the dye which releases histamine. You are not at higher risk for a dye reaction because of a shellfish allergy ...Read more
Is it likely to develop an allergy to benadryl (diphenhydramine)? I've seen 1 or 2 tiny hives and slight flushing, feel nervous, after taking it. I take dye-free.
Benadryl (diphenhydramine): Allergic reactions to Benadryl (diphenhydramine) are unusual but they do occur. Benadryl (diphenhydramine) does have side effects such as sedation or agitation. Hives and flushing can be seen with allergic reactions. A visit to the doctor may help sort this out. ...Read more
Not aware of testing: The risk of an adverse reaction to non ionic IV contrast dye is very low, less than 1 in 100 injections. Most of the reactions are mild and easily treated. Severe reactions occur in 1-2 per 10, 000 injections of IV non ionic contrast. If a person was severely allergic to many different things, perhaps a consultation with an allergist could be obtained. ...Read more
I have an allergy rash from hair dye. I have been taking Benadryl (diphenhydramine) for a few days and it has still not completely gone away. What should I do?
Is there a test an allergist can do that will confirm my allergy to antihistamines? I had hives after taking dye free benadryl (diphenhydramine).
I have true allergy to Benadryl (diphenhydramine) (had hives when taking the dye-free for a headache.) is allegra safe for me? And would it help my allergic reactions?
Yes: Allergy to Benadryl (diphenhydramine) is rare if at all present. Allegra is quite different from Benadryl (diphenhydramine) in structure and thus should be safe for you. Make sure you are not allergic to the gelatin on the Benadryl (diphenhydramine) capsules. Whether Allegra would work for you or not is another issue but it should be no less effective than benadryl (diphenhydramine). ...Read more
