How long does it usually take for Lipitor to lower cholesterol? Most people see their LDL cholesterol drop within 2 weeks after starting Lipitor, with the full effect reached in 4 to 6 weeks. When should you get a follow-up blood test? Doctors typically check lipid levels 4 to 12 weeks after the first dose to decide if the dose needs adjusting. Does Lipitor also lower blood pressure? Lipitor is not approved or prescribed for blood pressure. It lowers cholesterol; any small blood-pressure changes reported in studies are indirect and not considered clinically meaningful for hypertension treatment. How does Lipitor compare with blood-pressure drugs like amlodipine? Blood-pressure medicines such as amlodipine act within days, while Lipitor’s cholesterol benefit builds over weeks. They treat separate conditions and are sometimes prescribed together. What happens if cholesterol stays high after 6 weeks? Your doctor may increase the dose, add another lipid-lowering drug, or check for adherence and diet factors before deciding on the next step. When does the patent for Lipitor expire? The original U.S. patent for atorvastatin (Lipitor) expired in 2011, allowing generic versions to enter the market. Who makes the generic versions available today? Major manufacturers include Pfizer’s own authorized generic, plus companies such as Teva, Mylan, and Ranbaxy.
