Asthma Problem

Please let me know the medication / care I should be taking for my five year old son. The details of his ailments are as mentioned below:

He took mother's milk only for 10 months because another pregnancy occurs. During this period he is normal and no asthma attack happened.

After two months, he had his first acute asthma attack by way of wheezing and continues cough sequence. During the attack he often wakes up coughing in the last part of the night at 3-4 o clocks. Respiration and heart beat very fast.

This attack occur in both winter and summer seasons. The reasoning of attack some time I noticed that eating banana, ketchup, 7-up cold drink.

After homeopathy medication he recovers his breathe problem but cough take at least seven or more days. His color becomes yellowish.

My grand-father and a brother has asthma problem. Is there any medicine to stop transfer to next generation?


Please suggest medicine for my son;

For his Respiration and heart beat very fast
For continues cough (with no break in cough).
For his late night severe cough.
