I have been on Yaz for 2 years. I have had severe headaches since taking the medicine. I recently went to an urgent care clinic because my headache was so bad. My blood pressure was 167/120 and has stayed high despite being put on a diuretic this past week. I am only 24! I am normal weight, 63" 115lbs, and eat very healthy. Has anyone else experienced high blood pressure on Yaz?
