These drugs which you have been prescribed are to improve your general health and prevent you from the allergy
The drug telekast is a montelukast
, which mainly act by stabilizing the release of histamine
from the mast cells in case of allergic exposure and thus prevent you from the allergy. It is mainly used in prevention of asthmatic attack when some allergic exposure is causing the asthmatic attack. If your condition is because of some allergic reaction
causing this type of sign and symptoms than this can help you.
Another drug astymin-forte is mainly a multivitamin
+ milti mineral and have different amino acid
for the general well being and supplementation.
Since you have told that once you have investigation showing high eosinophils count in your blood, this can be because of that eosinophilia
, which some times cause respiratory symptoms. I would suggest you to consult a respiratory specialist and take treatment for this eosinophilia condition.
Another problem is the occasional cough and cold. This can be because as you are having more secretion in lungs in the form of phlegm which make you more prone to infection causing this thing. So once your excessive phlegm can be treated than this cough and cold hopefully will be gone.
Thanks and take care.
