I have just started using the above medicine and have noticed a severe drop in my blood pressure as well as a rise in my heart rate. Before using it my (BP) was around 118/71 and a heart rate of 60 ish. Now the figures are around the low 90/53 ish and a heart rate of above 80,these figures are all taken at rest. Additionally I have a slight headache and shortness of breath. My question is will these conditions persist with regular use and/are these conditions dangerous to me?
