I have been on lipitor for 21 months. However, not steadily. During that time period, when my husband and I were trying to have a baby, I'd stop it, then I'd go back. (Did not get pregnant). My point is, during the last 3 months, I have noticed a significant hair loss. On the top of my head, I am developing a bald spot. This would be greatly upsetting to anyone, but since I'm a 39 year female, I'm taking this pretty hard. My doctor claims, it's not the lipitor, the side effect would have shown up months earlier. A friend of mine, also said she had significant hair loss after 18 months on Lipitor. Why is my doctor so adamant that it cant be the Lipitor?
