I just started that medication too. Since my blood pressure tends to run low, I was told to take it only if my systolic is 120 or over and only if my bpm is 60 or above. Otherwise, everything might go to low. This means I have to be vigilant with taking my bp, which I haven’t done a very good job with.
Also, I was told to split the 25 mg- 1/2 in am and 1/2 in pm.
Not sure if this helps.
Hope you get some answers.
This disease is quite perplexing.
