Statin drugs: what they do and what to watch for

Statin drugs are the most common medicines doctors use to lower LDL cholesterol — the "bad" cholesterol that raises heart disease risk. If you've been told your LDL is high, statins usually come up fast because they reliably reduce heart attacks, strokes, and death in people with high risk. But how they work, who should take them, and what to watch for isn't always obvious. This page gives clear, practical points you can use when talking with your doctor.

How statins work — short and simple

Statins block an enzyme in your liver that helps make cholesterol. With that enzyme slowed, your liver pulls more LDL out of the blood, lowering overall LDL levels. Most people see significant drops in LDL within a few weeks. Doctors pick a statin and a dose based on your heart risk, age, and other health issues.

Ask your doctor what LDL target you should have. For example, people with existing heart disease or diabetes often aim for lower LDL than those at lower risk. Statins are one part of the plan — diet, activity, and blood pressure control matter too.

Side effects and liver checks — practical advice

Common side effects are mild: muscle aches, tiredness, or digestive upset. Serious problems are rare but can include muscle breakdown or liver enzyme changes. Your doctor will usually test liver enzymes before starting a statin and may check again later if you have symptoms. If you get unexplained muscle pain or dark urine, tell your doctor right away.

Statins can interact with some other drugs and supplements. For example, certain antibiotics and antifungals can raise statin levels and increase side effect risk. Always mention every medicine and supplement you take when your dose is chosen.

Not comfortable with the first statin offered? There are alternatives and different dosing options. Your doctor can try a different statin, lower the dose, or add non-statin drugs if needed. Lifestyle changes — losing weight, cutting saturated fat, and adding exercise — often help reduce the needed dose.
