Each person is different.
I like Claritin.
My Mom likes Zyrtec.
I hate Zyrtec. It makes me tired and IRRITABLE.
There is also Allegra for kids.
Again, each person is different. Each allergy med does work. But each person is different.
You might get, an air purifier for your home or the rooms or her room.
When I was a kid, my parents did that. FOR me.
It helps. I HIGHLY recommend this.
Also, when she is outside, then comes back in the house, have her change clothes. Why? Well because, lots of pollen/dust that is not visible to the eye, adheres to our clothing. And we bring it home. On our clothes. So, when she comes home, simply have her, change clothes.
And, wash her face with clear water, and wash her hands.
Having seasonal allergies or to pollens/dust is not fun. But it is not completely avoidable. I have that too. Plus, in Hawaii, we have "Vog." Which is, air smog from the Volcano. So we learn to live with it.
But you can do preventative things. Like I mentioned.
ALSO, when vacuuming the home, do NOT have her there. Do NOT have her in the same room. Why? Well, vacuuming kicks up a lot of dust in the air. Which we cannot see. My Mom's Doc, told her, do not vacuum, or use a face mask while doing it... or, do not enter a room that was vacuumed for 1 hour. Until the dust settles down.
No matter what allergy med you use, it has to be the "children's" version. AND you need to know about dosage.
I have those same allergies too. Mostly seasonal.
I tried those homepathic ones too.
It did NOT work, for me. Either.
