high blood pressure
"Diovan effectively controlled my high blood pressure for 2 years. Then suddenly I developed low potassium levels; fluctuating blood pressure, rapid pulse, ringing in the ears, nausea and deep tissue pain with chronic inflammation. The dose was dropped by 1/2. Sleep apnea began. It took three months- many-ER visits, two hospitalizations and cardiac monitoring to figure out what my blood pressure was actually doing. Eventually it took only 1/4 of the dose of the medication to "control" my pressure without causing side effects.  The onset of these symptoms without doctors recognizing them created concern for me about this medication. I recommend regular monitoring of your own blood pressure."
