Biaxin and hypertension

I have been on biaxin,flagyl,prevacid for 3 days and I am not taking it anymore. I was suppose to be on these meds. for 2 weeks for a stomach disorder I have. I was very sick in bed while on these meds. my symptoms where blurred vision,diarreah,chills,confusion,horrible metalic taste,I could'nt eat or drink anything and I called my doctor and he said keep taking it!!!!!! yes, believe it he did, so needless to say I 'm finding another doctor asap. I have hypertension and it also increase my heart rate and my pressure was high.
We go to the doctor because we are sick and need help and they prescribe meds. to us that makes us worse! We can't take them so we pay for prescriptions we can't take! I think when doctors prescribe something we can't take or they change it (oh, my mistake they should have to reinburse us)
