Pharmacy/olmesartan side effects


Dear sir,

I have sought your guidance as regards olmesartan 40. I have started it and my bp is under control since few days. I feel severe headache which appears to be a side effect. Will it disappear gradually ?

Or should I try telmisartan 80 in its place though I am not sure whether telmisartan is as effective as olmesartan.

I seek your views and not your recommendation. I shall highly obliged to receive your response.

In  comparative studies olmesartan has proved to be  more  effective than telmisartan, and in large clinical trials  neither drug produced any headache which you have experienced. As a result it is difficult to  comment on the same, I would suggest you continue it for a few days, bt if the  headache does not settle down please revert to telmisartan.
All the best
