Thanks for your query to us.
I hope eritel 80-5 has 5 mg amlodipine
and 80 mg telmisartan
yes, we must expect better result with this higher dose, as the maximum dose for telmisartan is 80mg per day only.
Please also see following things- Are you under some kind of stress? Do you check BP at same time everyday refraining from smoking
and tea for at least 1 hour prior to it? Have you gained some weight?
Hope this helps.
