My husband used to take Altace fo HBP. It wasn't working so his dr. put him on Lisinopril in Feb. of this year, 2007. He had to keep lowing the dosage until he reached 5mg. It knocked him on his ass, he has no energy at all, no sex drive, we have not had sex since Jan. He is tired, tired tired all the time. He also coughs but is a smoker, wakes up at night with his t-shirt soaked. He has told his dr. this and he says it's where his BP gets low and his heart is pumping trying to keep up with his body. He had bloos work done and has found out he's anemic. I don't know if the medication has caused this or not. Since June 2007 he has had to have 2 blood transfusions, has gone through scopes, more blood work and we are waiting results of the lastest done Aug. 7, 2007. He goes for a CAT Scan Aug. 21, if the dr. isn't satisfied with that he's doing a bone marrow test. Could this be the result of lisinopril? Anyone else having these systoms?
