Hi,
Thanks for writing your query.
After reading your post, I will also agree with your doctor that you are having
allergy to cold.
You should take precautions to avoid sudden change in temperature of the environment. Wear proper clothing while in A.C.
Avoid cold drinks, ice creams, etc.
Steam inhalation and gargle with warm saline water may be helpful.
Rotacaps usually contains a
bronchodilator or a
steroid which helps in bronchodilatation and proper passage of air.
Allegra contains antihistaminic which helps to control allergic episodes.
Viznil contains antihistaminic along with
Montelukast, which helps in preventing asthmatic attacks.
You can take viznil for control of your symptoms. Rotacaps can be taken whenever you are having breathing problems along with cough.
I would suggest that you should first get yourself clinically examined by your doctor and let him decide which medicine is best suitable to you.
I hope this is helpful to you.
Thanks.
