Ruth,
I was diagnosed with high bp several years before my first attack, and began taking bp meds to control it.(it must have been genetic because at that time i only weighed about 118lbs.)
(And i was diagnosed with MGUS about two years before the SCLS.)
I am presently on Benicar for my bp.
I was on a different one before the first episode, but after my second episode and SCLS diagnosis they changed me to the Benicar. I also use it along with hydrochlorothazide.
My effexor(for depression) also increases the bp.
After an episode, it is two to three weeks before i resume the Benicar, checking my bp thru out the day.
If my bp is high i struggle with severe headaches.
During my second attack, they did several cts, one of my heart which showed left ventricular hypertrophy(Arturo and Dr.Greipp feel free to correct my medical lingo), which is a thickening of the heart that develops with long term uncontrolled high bp.
After changing to benicar, (getting my bp closer to 120/80 or 110/70 rather than in the 130s), my most recent ct of my heart showed the heart had healed and was back to a normal size.
When my doctor told me this good news, i replied, "Praise God!",( I'm sure he thought, "and benicar, too.")
I am not a doctor, but i think 180/100 is definitely not safe, more than likely considered "severe hypertension".
Your physician should be able to find a bp med that is right for you. It may take several tries before you find what's best. Some cause side effects like sleepiness, fatigue, headaches, etc... I know because initially i went thru about three different ones before finding one that made me feel normal.
sincerely, marilyn
