What if statins are not enough to lower cholesterol?

If statins are not sufficient to lower low-density lipoprotein (LDL) cholesterol to the target range, your doctor may recommend additional treatment options. These options include adding other cholesterol-lowering medications or adjusting the statin dosage, while continuing to adhere to healthy lifestyle changes, including diet and exercise [1].

When are statins considered insufficient?

Statins are the first line of treatment for most cases of high cholesterol, as they work to reduce cholesterol production in the liver and increase the liver's ability to remove LDL cholesterol from the blood [1]. However, statins alone may not be sufficient in some cases, especially if LDL cholesterol levels remain very high, if the patient is at high risk for heart disease and stroke, or has a history of these conditions [3]. Under these circumstances, doctors may resort to adding other medications to enhance the cholesterol-lowering effect.

Additional Pharmacological Options

There are several types of medications that can be used in addition to statins or as an alternative if statins are not tolerated:

• Cholesterol absorption inhibitors: These medications work by preventing the absorption of cholesterol in the body and can be used if statins alone do not lower cholesterol sufficiently or if the patient cannot take statins [1].
• Bile acid sequestrants: These medications prevent the absorption of bile acids in the intestines, which prompts the liver to use cholesterol found in the blood to produce more bile acids, thereby lowering the level of LDL cholesterol [2]. A doctor may prescribe them if the patient cannot take statins or if statins do not lower cholesterol sufficiently [1].
• PCSK9 inhibitors: These medications work by blocking a specific protein (PCSK9), which helps the liver remove LDL cholesterol from the blood [1]. A doctor may prescribe them with statins if the patient is at high risk for complications such as heart attacks or strokes, or if they have familial hypercholesterolemia [1].
• Niacin (nicotinic acid): This is a type of vitamin B that reduces the amount of fat the liver produces, which lowers LDL cholesterol and triglycerides, and raises high-density lipoprotein (HDL) cholesterol [1]. You should consult your doctor before taking it in high doses due to potential side effects [1].
• Fibrates: These medications are primarily used to lower triglyceride levels and may also increase HDL cholesterol and slightly reduce LDL cholesterol [1].

Important Considerations and Next Steps

When the doctor determines the appropriate medication and required dosage, they take into account your cholesterol levels, your risk of heart disease and stroke, your age, any other health issues you have, and the potential side effects of the medications [1]. It is important to continue taking prescribed medications and undergo regular cholesterol checks to ensure levels remain within the healthy range [1].

Medications do not treat cholesterol permanently; rather, they help manage it [1]. Therefore, one must adhere to healthy lifestyle changes, including diet and exercise, even while taking medications [1].
