How long does it take for liver enzymes to rise after starting Lipitor? Liver enzymes can increase within 2 to 4 weeks after patients begin Lipitor. This early rise appears in clinical studies where transaminases (ALT and AST) show occasional elevations, but most cases stay mild and asymptomatic. How common are these changes? About 0.7% of patients on atorvastatin reach enzyme levels three times the upper normal limit. Higher doses bring larger risk. Higher doses also produce earlier and clearer increases. What happens if liver enzymes stay elevated? Doctors monitor enzymes at 6 to 12 weeks and then periodically. Persistent elevation may prompt dose reduction or drug discontinuation. Discontinuation lets most levels return to normal in 1 to 4 weeks. Why does Lipitor affect liver enzymes? Lipitor belongs to the statins class. It interferes with cholesterol synthesis in the liver, which can trigger mild hepatitis-like reactions. This mechanism accounts for the observed enzyme changes. When does the patent expire for Lipitor? Lipitor's primary patent expired in 2011. Generic versions entered the market right after.
