Hi,I had gone through your query and understand your concern.
It seems that your daughter has poor
asthma control.This is very important to have good asthma control during
pregnancy since it may affect the child.
If you could mention the name of the inhalers,it would help me to give you a precise suggestion.
If I were the treating physician ,I would first confirm the diagnosis by objective test,check for triggers and follow up thoroughly for any abnormality related to pregnancy.
Then I would I advise
steroid inhaler twice daily and
salbutamol inhaler as required for asthma and other medications if required.
Since this is a prescription medicine ,so my opinion is :please consult with a respiratory medicine specialist to confirm the diagnosis and get treatment accordingly.
Please do not worry.Asthma will be under good control with proper medication.
Wish your daughter safe pregnancy.
