Hi welcome to Health care magic forum.
Thanks for asking a question to H.C.M.F.
Your sisters son who is 9 months old is suffering with cold
and nose block. doctor gave deriphyline injection, and nebulizer
with asthanol, infection and symptoms reduced to 90%, still you are doubting whether the dose and the drug suits to the child or not.
It is rediculous to think this way, the doctor examined the child, judged the condition, and prescribed, and he didn't prescribe for a long time. And the kid is happy with it.
There are side effects with the drugs, but applicable only to some people, if thought before using it no one can use any drugs.
That is why one should be concerned when the patient is abnormal, after taking the drug.
If the child is having the disease since child of one month he will be cured of it by the age of 3 years.
Don't worry about all these things your doctor will take care of all these things. Avoid giving fruits and juices when he has the cold or cough
I hope you got my point in the reply.
