Amlodipine
"I was put on amlodipine and had been taking it for about 2 months.  I was not happy when I found that this medication could possibly react with simvastatin - so I asked the doctor to switch it - he said let it go for a couple of months to see.  So I did.  Blood pressure still wasn't getting close to normal - and I was also getting horrible chest pains, horrible tinnitus - seems like I was holding water.  I finally got him to instead switch the amlodipine to Lisinopril/ hydrochlorothiazide 10/12.5 mg dose.  By the second day of taking this my blood pressure totally returned to normal 120/80 - right around there.  I was ecstatic!!! It's been about a week now on the new."
