Key takeaways
Simvastatin (Zocor, Flolipid) and pravastatin (Pravachol) are both statins used to lower cholesterol and reduce the risk of heart problems like heart attack and stroke. Simvastatin is available in both tablet and oral solution forms, while pravastatin is only available as a tablet. Simvastatin is typically taken at night because it is short-acting, whereas pravastatin can be taken at any time of day, though nighttime is often recommended. Simvastatin has a higher risk of causing severe muscle damage (rhabdomyolysis) compared to pravastatin. Additionally, simvastatin interacts with more medications and requires you to avoid grapefruit, which is not a concern with pravastatin. Both medications are not recommended during pregnancy or breastfeeding. Both medications can cause liver problems and should be used cautiously in people who drink alcohol regularly.
