( ED ) you are facing can be caused by the high blood pressure
itself and it can also be caused by the medicine ATENOLOL
,being taken by you.
It is very difficult to say which of these factors is responsible more for your erectile dysfunction or it may be due to both the factors.
If ED is troubling you ,then you must consult your doctor and try to switch your ATENOLOL to some other medicine.
A group of drug called as ARB's like TELMISARTAN
can be prescribed to you which not only stops your trouble of ED but it may improve your sexual function also.
Make sure that keeping your BP normal is more important than any other thing.
