how long does it take for statins to work

Statins typically begin to work within about 4 weeks of regular use. During this time, cholesterol levels should start to drop noticeably if the medication is taken as prescribed. More specifically, LDL cholesterol can decrease significantly within 4 to 6 weeks, with some effects starting as early as the first few days, especially on higher doses or more potent statins like atorvastatin or rosuvastatin. The maximal cholesterol-lowering effect is usually reached around 6 to 8 weeks after starting treatment. Statins are most effective and safest when taken consistently over a long period, often many years, to maintain reduced cholesterol levels and cardiovascular risk. Although people do not usually feel any different, the treatment reduces the risk of heart attacks and strokes. Missing doses can blunt the effect of statins, so adherence is important. Overall, expect significant changes within about a month, with continued benefits over time.
