My bp is running 115/88 and sometimes even 103/89 most of the day.if i take bp meds it drops too low.my dr dont think it's high enough for meds?

I agree: The top number or systolic blood pressure is very normal and suggests if medications were used it would drop that measurement even further and you might have symptoms such as dizziness. Unfortunately, we don't have a medication that would only affect the diastolic blood pressure (bottom number). Aggressive lifestyle approaches are indicated: ideal weight, limit alcohol & salt, daily exercise
