You will be killed?

How many kinds of medicine do you take everyday?
I take four and one supplement now. I used to take six before.
We often hear the assertion that you will be killed by too many medicines.
It was usual before for us to take medicines doctors offered.
Now some people including doctors suggest that we should refrain from taking too many medicines.
They say that we would be killed if we follow the orders of doctors.
So I have stopped taking two medicines reading the doctor’ face.
