Hi! Yes, I started losing my hair after taking Lisionpril for about a month. My hair's very fine & thin anyhow, so I can't afford to lose more. It's definitely the medication! Also, other symptoms I told my doctor about caused her to prescribe another medication: Cozaar. I'm afraid to take another, however. I just stopped Lisinopril Oct. 1 and I'm having terrible cramping at the back of my thighs. I guess one should gradually lessen the dosage instead of suddenly stopping it. Tonight I had to take 1 Lisonpril because the pain was so bad (my blood pressure suddenly went up as well...146/85). I was put on this stuff because I was recently diagnosed with type 2 diabetes and it's supposed to protect my kidneys.
