She seems to have a relapse.
Usually they recommend an inhaler.
Make sure it is not Bronchitis or something...
"wheezing" in a child per asthma, is not always present.
The asthma symptoms in a child, is different sometimes.
Claritin, is fine.
Zyrtec is similar.... but not all antihistimines work for everyone... thus, some people take Claritin, some take Zyrtec. Each person being different.
If she has a sinus infection.... there will be post-nasal drip... down the throat. It can sometimes then, cause a lung infection.... because of the mucous. I had that happen to me before. I have Asthma as well. In my case, it turned into a bronchitis and then Pneumonia. All started by a head-cold.
"Coughing" can be caused by 2 things:
1) a head-cold... because post-nasal drip causes coughing and throat irritation
2) a lung/chest cold or infection.
Thus, a "cough" does not always indicate that the origin is the chest, per say.
Her cough is probably worse at night because she is laying down... thus, the mucous just sits there and gets stuck in her throat.
Watch her and make sure she does not have any fever. A fever would indicate an infection or a secondary infection....
Yes, take her to the Doctor again.
all the best,
Susan
