Thankfully through diet and exercise, I am maintaining a blood pressure below 120/80 so I don't need the drugs for now.
My HMO doctor prescribed me the diuretic knowing full well that I was taking lithium. He said it was ok, which shows his familiarity with lithium.
My Pdoc got my blood results and told me to go off lithium immediately. Since I had been on the same dose of lithium for almost 3 years, I knew it was the diuretic that caused the high lithium level.
The way I dealt with it was to stop the High Blood pressure diuretics. I was simply asking for advice on other hypertension drugs here so I can go into the doctor when I need to with some recommendations for him to consider. Being bipolar puts me in a category that not all HMO docs deal with. And no, they do not communicate, both have more patients than they can handle and I relay information between the two.
