... insurance will not pay for my benicar anymore. In June I was changed to losartan HCTZ I was on that for 4 weeks it didn't bring the pressure down so they changed me to Irbesartan HCTZ, I had a real bad headache on that and felt ill, so I could not take that, now today the doctor changed me to Lisinopril hctz, I have so much anxiety about starting this one in the morning. Seem I can't take the one that worked until I have tried all the others, something about the step program with the insurance. I keep reading about all the side effects and am worried about the new drug tomorrow. Is there anyone that has had good results with this drug
