Supraventricular Tachycardia
"I have SVT and high blood pressure. After 10 years the dr. switched me to Metoprolol from Atenolol. The medication works great with one caveat - you MUST check which brand you&#039;re getting.  The dr. changed my dosage, which resulted in different dosage pills. Suddenly my blood pressure jumped and my heart was beating erratically, chest pains (which I&#039;ve never had), and I was constantly worn out. I checked the brands of the former medications and the new and found they were different. I switched back to the old meds at the new dosage for a couple of days and within 1 day my blood pressure dropped 20 points and I felt back to normal. Now the pharmacy special orders the Mylan brand, as the Aurobindo doesn&#039;t work at all."
