Should I keep a cat even if it causing allergy problems with my children ages 2 thru 7?

Should I keep a cat even if it causing allergy problems with my children ages 2 thru 7?

Depends: Several factors here. I usually never recommend it if the family is attached to the pet, but if it is causing severe symptoms, you should sequester the animal out of the bedrooms and living spaces. Then make sure you thoroughly rid those areas of cat dander as it is a potent and tenacious allergen. ...Read more

Can a parents allergies be passed on to their children?

Can a parents allergies be passed on to their children?

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

How severe does a nut allergy need to be to warrant carrying around an epi pen?

How severe does a nut allergy need to be to warrant carrying around an epi pen?

Always carry EpiPen (epinephrine): Peanut and tree nut allergies have some of the highest rates of fatal anaphylaxis, and Epinephrine can be life saving. Unfortunately, you cannot predict how severe a person's reaction will be based on a previous reaction--there are too many variables. For that reason, in general we recommend that everyone with any history of reaction to these foods carry an epi pen. See an allergist for more info. ...Read more

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?

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

Pick one: While both zyrtec (cetirizine) and Claritin (loratadine) are approved for treatment of allergies in children, it is rarely necessary to use both at the same time. In my experience, Claritin works for many and zyrtec works for most patients. While there is little harm to combining these, it doesn't add to the effectiveness. ...Read more

Yet people do acquire allergic reactions to new things as they get older, and it could be real. Blood tests can reveal if it is a true allergy which would likely persist over time vs a non allergic reaction that may not be real. ...Read more
