Valturna
"I was on Valturna 300MG for six months and it did do a good job maintain my high blood pressure.  While on this medicine I suffered daily unstable angina with severe attacks 1 to 3 times per day; severe sinus problems; low red blood count with mild anemia; congestion turning to pneumonia; and extreme weakness and fatigue.  I accidentally ran out of the medicine for four days and all these symptoms stopped. Went off the medicine for three weeks and was a new man and felt great. My doctor didn't believe me so I went back on it and on the 3rd day had another severe angina attack. I stopped the medicine now for 3 months, no symptoms. While experiencing these symptoms I had all the heart tests including Angiogram, Stomach Endoscopy, and Gall Bladder Tests all tests were negative."
