Denavir Allergy In Children
Denavir allergy: Denavir (penciclovir) is an antiviral drug. An allergy occurs when your body’s immune system creates antibodies to a foreign substance causing a reaction that can be mild to severe. For potential adverse effects see: http://www.rxlist.com/denavir-drug.htm ...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
Good drug: This anti-herpes virus drug works in two ways: the active triphosphate is present at much higher concentrations in virally infected cells than in uninfected cells; and the drug targets viral dna polymerase to a much greater degree than human dna polymerases: this means it doesn't kill healthy cells. ...Read more
Different: While they are both topical treatments for cold sores (herpes simplex), they are different medications. They both may shorten the duration of an active cold sore outbreak somewhat, but through different mechanisms. Abreva has an advantage in that it is available without a prescription. ...Read more
Yes: All medications take time to work -- and viral replication is not automatically stopped just because a medical is applied that moment. So -- they can still be infectious for some time after the medication is started (generally a few days). ...Read more
My dentist gave me denavir (penciclovir) for canker sores and I have used as directed ut they are still there?
Get Valcyclovir: canker sores are painful in the mouth and are usually caused by the herpes virus. Stress, chocolate etc.. Can cause these to become more prevalent and more painful. Valcyclovir is an antiviral drug that your doctor or dentist can prescribe for you that should help alleviate the pain within a day. However if it does not respond to it. It may not be viral and will respond to laser therapy ...Read more
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
Breastfeed!: Breastfeeding is shown to be protective for children with a strong family history of allergies. If unable to breast feed, try a hypoallergenic formula such as "nutramigen" or "alimentum". Try to avoid introducing baby foods until 4-6 months of age; once you do, introduce them slowly. Interestingly, exposure to dogs & cats appears to reduce the risk of becoming allergic to those household pets! ...Read more
Nasal, eye, skin: Children will exhibit sneezing, itchy nose/eye, stuffy nose or cough with close exposures with pets. If licked by a cat or dog and allergy is present, a rash could develop at that site. The allergies could manifest as asthma with cough, wheezing or difficulty breathing. Typically a pattern will be seen, but if it is an indoor pet, the symptoms may be continuous. ...Read more
No: The pain is minimal with skin testing, similar testing can be done with a blood test which requires some blood being withdrawn with a needle. ...Read more
