Thanks for your query.
Benitec-40 is a medicine prescribed to control high blood pressure
It contains Olmesartan
and this drug belongs to ACE inhibitor
In few persons taking this drug or any drug from this group dry cough
is seen as a side effect of this medicine.
In case you have dry cough you should consult your doctor and get medicine changed but if you tolerate it well and do not have any side effect it is a good medicine.
As for Homochek it will better if you can write what is the content of this medicine as I guess it is a local brand.
Probably it is for protection from heart issues or blocked arteries.
I would suggest you to continue your medicines as advised by your treating doctor and you should be fine.
