[|Human|] I m a 63 yr. old female gastric bypass /roux-en-y Aug. 2013. Been on Losartan Potassium 100mg. qd for awhile now, put on Bystolic 5 mg. maybe 6 mos. before surgery both meds are taken q AM I m having periods of funny strange drifting feelings lasting approx. 30 sec. pulse rate regular running 55-61..BP 128/76. Could this be the two bp meds fighting each other, my BP is nothing as it was before the surgery (always elevated) Which med should I start to taper off of first? Weight has gone from 269 to 194.
[|AI|]  Hello! Thank you for asking on Chat Doctor! Your blood pressure values and heart rate seem to be within the normal limits. Regarding your concern, I would explain that losartan and nebivolol both increase potassium levels in the blood. I recommend performing blood electrolytes levels, to monitor potassium levels and avoid any abnormal increase, which may lead to bradycardia. The decrease in your weight is another factor contributing in lowering your blood pressure. This is a good way to control your blood pressure. If your blood pressure gets lower, I recommend consulting with your doctor to consider the possibility of lowering systolic dose (which also contributes in a low heart rate). Hope to have been of help! Best regards,
