I was started on low dose Lisinopril 2.5 mg./day a few weeks ago. My pharmacist told me there are absolutely no side effects except for possibly an ACE inhibitor cough. That immediately made me think this drug was too good to be true. I am very sensitive to medication and have only had the need to take an occasional tylenol or motrin - ever. Usually I thrive on stress and am the type of person to go, go, go all day and once I hit the sofa after supper, I relax. Now I just feel unusually tired and wiped out during the daytime. I started with a headache yesterday that took 2 tylenol to make go away. I am able to get energy bursts, but then the tiredness! I have felt some fluttering of my heart as well. My hands feel unusually cold and achy when I type or hold the steering wheel of my car or a shopping cart. I am usually very focussed, but things are a little fuzzy in that department from time to time over the past few days. My most recent BP was 114/61 - perhaps too low? I see the MD next week for a follow up. If I tell her I'm unusually tired, she will try to put me on thyroid meds (I have been borderline for years). She also said my blood sugar and cholesterol bear watching. You know, I've been healthy for 52 years and all the doctor can say is that now my life is catching up with me. I can't help but think she has some long term pharmacological cocktail planned for me!
