Has anyone here had any sustained success with bp medicine? If so, how long did it take to find the right ones? I was diagnosed with high blood pressure in 1999. My doctor at the time prescribed Labatalol and Cozar. They both worked really well for years, but within the last year they don't seem to work anymore. The doctor I see now wanted to double the Labatalol, but I was concerned about it. He said he will prescribe another medicine for me, Norvasc. I know there are a lot of medicines for blood pressure, but so far my doctor has only recommended these three. I'm really concerned about taking three medicines now, especially since the first two don't seem to be effective anymore. Thanks for your help.
