Isovue Allergy In Children
Contrast allergies.: Isovue is a contrast agent often used in CT scanning. If someone is allergic, they may have more mild symptoms such as hives after an injection. More significant reactions include feelings of tightness in throat, drop in blood pressure, or facial swelling, shortness of breath, anaphylaxis. Severe allergies are not common but can occur. Discuss any history of prior allergies or asthma with doc ...Read more

All idodinated contrast agents used for radiographs can cause kidney injury. The risk is proportional to your level of renal function and they should be avoided if kidney function is impaired.
If it is absolutely necessary to use them special preparations to reduce the risk can be taken. ...Read more
Allergy? Renal prob?: Isovue is a common intravenous contrast agent though can be administered by other methods. It is iodine based so there the risk of allergic reaction. Additionally, if you already have problems with your kidney function there is a risk of having acute worsening and you should consult with your treating physician before receiving IV contrast. ...Read more
Contrast Agent: Isovue is a contrast agent usually administered through an IV route for an imaging study. When used appropriately is safe with no side effects. Some can be allergic to the agent. Allergic reactions can range from minor such as a rash to more severe reactions such as anaphylactic shock. Sometimes it can cause reversible or irreversible decreased kidney function which is usually dose dependent. ...Read more
Probably not: Two of the best, most rigorously conducted and analyzed studies done in the last few years came to nearly identical conclusions: with normal kidney fxn to begin with modern iodine contrast agents used properly do not result in more kidney problems than is seen in the general population of patients who have medical imaging. In severe kidney disease pts some caution is still needed. ...Read more
It is possible: Iv contrast can cause temporary kidney problems. If your kidneys are not functioning normally in the first place, they are more susceptible to this. Your doctors should make sure that the benefits of the test that requires contrast outweighs any risks. There are medications that help reduce the risk if you must have the test. ...Read more
Not in Normal people: Patients with compromised kidney function are the only one suffer this complication. Enough fluid intake before and after administration of isovue will help on those patients. A person with normal function should not worry up to 150 ml of Isovue injection. ...Read more
Can having sp. Injections w/ lidocaine, Depo-Provera medrol, (methylprednisolone) isovue contrast dye affect a drug urinalysis?
No: This will not affect drug screens.Get a more detailed answer ›
Exposure + Genes: One needs both a genetic component and "exposure" to a said allergen to develop an allergy. There is a growing support over the past 20 years, that growing up in an environment which is "too clean" can also lead to development of allergies down the road. Either way, allergies are on the rise. ...Read more
Nut allergy: Maybe. Your children may have inherited genes from you that make them more likely to develop an allergy, but they do not inherit a specific allergy to a food e.g. Nuts. The children have to be exposed to food proteins in the diet, before an allergy can develop. Once one develops an allergy then they are always allergic and need proper medical attention to prevent severe problems. ...Read more
Allergy tests: There are several types of testing. Some involve certain types of blood tests. Another method is to do a series of skin tests done by pricking the skin and applying different allergens. Other tests are provocative tests that can involve challanging the patient with allergic materials. Testing should be done by doctors specializing in allergy to obtain the best results. ...Read more
Skin & blood tests: Prick testing with allergenic extracts or fresh foods can help confirm allergy, as can blood tests for specific ige antibodies (rast-type tests). However, both types of testing can produce false positive results, and confirmation with food challenges may be needed. ...Read more
Not exactly: The ability to react to certain proteins in an allergic way is passed on from parents to their children, but a specific allergy is not. So if a mom is allergic to pollen and the dad is allergic to fire ants, their child may develop allergies but it may be to a food instead. If 1 parent has allergies, the child is 50% likely to develop allergies, but it's a 75% chance if both parents are allergic. ...Read more
Can I as a 46 year old, take children's Benadryl. It's all I have in the house and my allergies are terrible.
Okay to use: Okay to use children's Benadryl. Dosage will be 20 ml (4 teaspoons) per dose. ...Read more
Where can I find a statistic for the number of children who died from allergies causing anaphylaxis in the u.S.?
Only overall numbers: The incidence of anaphylaxis in children is unknown. Estimates of anaphylactic deaths (from drugs, foods, insect stings, and latex) in the us are 0.002 percent annually (2 per 100, 000): 500 fatalities from penicillin anaphylaxis; 40 fatalities from bee stings; 125-150 from food anaphylaxis. ...Read more
My husband has nut and fish allergies. I have 4 children, 2 without allergies should I get rest of kids tested before giving them these foods?
I give my 17mnth old 1/2 teaspoon of children's zyrtec (cetirizine) for allergies but some days it's not enough. Can I increase the dose or try something differ t?
Do not increase: A 17 month old should not have allergies to inhaled items like dust or pollen. Zyrtec (cetirizine) could cause drowsiness and I would avoid long term use of zyrtec (cetirizine) in your child. If your child has a runny or stuffy nose that is unresponsive to zyrtec (cetirizine) then see your doctor to make sure there isn't an infection brewing. ...Read more
Yes: Not all of the food allergies are created equal. Food allergies like dairy, egg, wheat tend to be outgrown. Tree nut and peanut are less likely (although recent studies suggest that 20-30% outgrow the peanut allergy). Environmental allergies tend to "grow on you" with time. Note: the allergy test may remain positive despite the child having outgrown the allergy. Consult with an allergist. ...Read more
It depends: It really depends on the age of the child, and whether you're talking about food or environmental allergies. I generally will skin test children over age 2 for environmental allergies, while many younger kids need food testing. In terms of frequency, children with environmental allergies may benefit from repeat testing after 2 years, as their allergies can change as they get older. ...Read more
Hygiene hypothesis: The immune system has two opposing arms, one makes protective antibodies against bacteria and viruses, the other makes allergic antibody. One theory is that early antibiotic use disrupts the gut flora which tips the scale away from fighting infection and more toward making allergic antibodies. Clean environments might be at fault as well, farm kids don't get allergies as much as city kids. ...Read more
Sometimes: But not all the time. Nasal allergies are not a frequent cause of a really bad persistent cough. In a child with allergies and a really bad cough (assuming no fever) I would be concerned about a reactive airway/asthma type condition. If the child also had eczema I would be even more concerned. ...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
