Yes, my husband is taking Donepezil. Can that make him feel dizzy & weak? He also is one Prevastatin, 40 mg Lisinipril 10 mg Aspirin 81 mg Dexilant 60 mg Pure Fish Oil Vit B-100 Complex Vitamin D3 4000 iu. He takes each one daily. He had heart surgery 16 years ago & our family Dr said after heart surgery, they usually put you on Beta Blockers. He was doing fine until about 2 months late, he started having the weak, dizzy, faint spells. After a while I convinced the Dr s he wasn t having these problems until he started taking Beta Blockers. So he s off them now, but still having the same feeling sometimes.Is one of the medications he s taking interfering with the Donepezil.
