I began taking Midodrine 2.5 mg at 8 a.m. and 2 p.m. as needed if BP is below 95. Because I was still dizzy, dosage was increased to 2 pills at each time if needed. This seems to help for about three hours and then wears off. Also, should not lay down after taking this med or 3 to 4 hours before bedtime. Try to follow directions, but difficult, with other prescriptions since also using Eliquis, metoprolol succinate and digoxin. I'm 86 & can't figure out if I'm hypo or hypertensive. It seems to be a game of dice figuring out how to take the meds. However, haven't had any blackouts or AFibs for about 4 months, just weakness, numbness in feet and hands and fluttering when getting up or laying down too fast. Med also affect emotions and sleep patterns.
