Amlodipine
"I am a 62 year old male who just entered the VA medical system. I have been taking Amlodipine for about 40 days and am now having intermittent swelling of my ankles and feet. This is new in my life. I have had ringing in the ears for over 30 years,  and I am able to ignore it. But I have noticed it getting louder also. This is a symptom in 1% of new patients. I will see my doctor and the Pharmacy tech in the next 3 days. Sleeping with my feet elevated over my heart worked well last night. I will ask to get off this calcium channel blocker and check for side effects on the new one. This product is also for Angina, I don't have that. Just elevated blood pressure."
