high blood pressure
"I was on lisinopril 10 mg for years and years but my BP kept going up. On Monday the Doctor started me on lisinopril 20/25 because my BP was 180/110.  This ok the meds Tuesday, Wednesday, and Thursday without problems.  Friday I fainted but thought I was sick, Saturday I fainted again 1.5 hours after taking the dose.  Don't know if I should drop back down to 10 mg for Sunday and Monday but will be going into the office first thing Monday morning!"
