Amlodipine
"I'm currently on  Amlodipine 5mg tab- The first 72-96 hours on this medication were very rough-very severe headaches, palpitations, dizziness, etc.  After the 3rd day, the headaches subsided and by the 5th day they were gone.   BP had been elevated due to non-tolerance from previous med combo.  By the end of the 1st week BP was down into the 120s over 80s.  So far I have been using this med for just over one month without any major side effects other than slight water retention leading to slight swelling of hands and ankles. My weight has remained steady.  



The med worked for me and I am glad as I had been trying so many different types of med to control BP that I was starting to lose hope."
