Beta blocker medication symptoms and conditions

I have been taking Lisinopril for about the last maybe 8 to 10 years. It started with 20 miligrams and has now gone to 40 miligrams. Recently my pharmacy change the manufacturer of their Linsinopril. My face is extremely dry, as well as my hair has dried out so bad, that I am beginning to loose my hair. I honestly just received revelation of this on last night, as I could not figure out why I would stay so dry. I try to drink lots of water, but it seems that I am literally drying out. And to be honest my hair has had so many issues since being on this high dose of Lisinopril. Has anyone experienced dry skin or hair, resuluting in hair loss or extremely dry skin?

I was given Yutopar when I went into premature labor with my first son in 1992. When I went into premature labor with my secon son 2 years later, I was given brethine. My doctor said that Yutopar was taken off of the shelves because it had caused heart defects in the babies.
My first son has been diagnosed with Long QT Syndrome and has been placed on beta blocker medication. My other 2 children, my husband, and myself have not been diagnosed with genetic LQTS.
Is there any correlation between Long QT Syndrome and Yutopar? Please let me know...
