My doctor has me on Atorvastin. I was seen two weeks ago and I was taking 1/2 of a 25 mg tablet every day. When I was at his office my heart rate was high and my blood pressure low. My dad dropped dead at age 68 of a heart attack. My brother died in shower of massive heart attack at 68. My doctor upped my Atorvastin to 25 mg per day and it's not agreeing with me. My heart is pounding hard and I get dizzy and I do t feel well. Could it be the dosage being upped that's causing this
