When I was first diagnosed with high bp, I was put on one of the medications ending with 'piril'. I started having the most dreadful coughing fits, totally out of control, and was sent to the local hospital, chest clinic. The professor in charge put me through a battery of tests, most of which came up pretty clear, and then he told me that he was certain that his first reaction that it was the bp tabs that was causing it. So, he had to order my GP to change this medication and within three months this debilitating cough disappeared. However, the Telimisartin did not really bring down my bp and I became quite worried anytime anyone needed to take it, knowing that I would get a high reading. Eventually, another GP told me to stay with that and also gave me another pill. Together these work magically, my bp is within reasonable rates most of the time and there are no side effects. Took me nearly ten years to reach that point.
As has been said, there are many different bp tabs out there, it does take experiment and time to find the correct ones for each individual.
