Statins are among the most commonly prescribed cholesterol medications. They lower low-density lipoprotein cholesterol, commonly called LDL cholesterol, and can reduce the risk of heart attack, stroke, and other cardiovascular complications in appropriate patients. A statin's value shouldn't be judged only by whether it moves a lab number — the bigger question is whether it lowers your actual cardiovascular risk while remaining safe and tolerable.
Common Statin Medications
Examples include:
- Atorvastatin
- Rosuvastatin
- Simvastatin
- Pravastatin
- Lovastatin
- Pitavastatin
- Fluvastatin
Statins vary in strength, metabolism, dosing, interactions, and ability to lower LDL cholesterol.
How Do Statins Work?
The liver produces cholesterol.
Statins block an enzyme involved in cholesterol production. They also help the liver remove more LDL cholesterol from the blood.
Their value is not limited to improving laboratory numbers. Certain statins have demonstrated an ability to reduce cardiovascular events in patients with heart disease or elevated cardiovascular risk.
Who May Be Prescribed a Statin?
A healthcare professional may consider factors such as:
- Existing cardiovascular disease
- Previous heart attack or stroke
- LDL cholesterol level
- Diabetes
- High blood pressure
- Age
- Smoking
- Family history
- Overall cardiovascular risk
A cholesterol result should be interpreted within the larger clinical picture.
Do Statins Cause Muscle Pain?
Muscle aches are among the most discussed statin concerns.
Patients may describe:
- Soreness
- Cramping
- Weakness
- Heaviness
- Reduced exercise tolerance
Muscle symptoms have many possible causes, including exercise, thyroid disease, vitamin deficiencies, other medications, and underlying muscle conditions.
Do not stop a statin without discussing the symptoms with the prescriber. Possible approaches may include:
- Reviewing interacting medications
- Checking relevant laboratory tests
- Adjusting the dose
- Trying a different statin
- Changing the dosing schedule
- Considering a non-statin treatment
Severe muscle pain, profound weakness, fever, or dark urine requires prompt medical attention.
Can Statins Affect the Liver?
Statins can affect liver enzymes, but serious liver injury is uncommon.
Tell your healthcare professional about:
- Existing liver disease
- Heavy alcohol use
- New abdominal pain
- Severe fatigue
- Yellowing of the skin or eyes
- Dark urine
Monitoring recommendations depend on the patient and medication.
Do Statins Cause Diabetes?
Statins may slightly increase blood-glucose levels in some patients.
For people at meaningful cardiovascular risk, the reduction in heart attack and stroke risk may outweigh that concern. Treatment decisions should be individualized rather than made from a single side-effect headline.
Can Statins Interact With Other Medications?
Yes.
Potential interactions can involve:
- Certain antibiotics
- Antifungal medications
- HIV medications
- Transplant medications
- Some heart medications
- Grapefruit with selected statins
- Other cholesterol-lowering medicines
The interaction risk differs among statins.
Provide the pharmacist with a complete list of prescriptions, OTC products, vitamins, and supplements.
What About Pregnancy?
FDA removed the strongest blanket pregnancy prohibition from statin labeling in 2021, but it continues to advise that most pregnant patients should stop statin therapy. A small group of exceptionally high-risk patients may require individualized decisions with their healthcare professionals.1
Patients who are pregnant, planning pregnancy, or breastfeeding should discuss their medication plan promptly with the prescriber.
What If One Statin Is Not Enough?
Other cholesterol-lowering medications include:
- Ezetimibe
- PCSK9 inhibitors
- Inclisiran
- Bempedoic acid
- Fibrates
- Selected omega-3 prescription products
These medicines are not interchangeable and may target different lipid problems.
The Bottom Line
A statin should not be judged only by whether it changes a cholesterol number. The larger question is whether it reduces an individual patient's risk of heart attack, stroke, or another cardiovascular event while remaining tolerable and safe.
Frequently Asked Questions
Should I stop my statin if I get muscle aches?
Don't stop without talking to your prescriber first. Muscle symptoms have many possible causes, and options like adjusting the dose, switching statins, or changing the schedule can often resolve them without giving up the cardiovascular benefit.
Do statins damage the liver?
Statins can affect liver enzymes, but serious liver injury is uncommon. Tell your healthcare professional about existing liver disease, heavy alcohol use, or symptoms like yellowing skin or dark urine.
Can I take a statin while pregnant?
FDA removed the blanket contraindication in 2021, but still advises most pregnant patients to stop statins. A small group of very high-risk patients may need an individualized decision with their healthcare team.
Do statins cause diabetes?
Statins may slightly raise blood glucose in some patients, but for those at meaningful cardiovascular risk, the reduction in heart attack and stroke risk generally outweighs that concern. This should be an individualized discussion, not a single-headline decision.
A statin isn't just a number-changer. Ask whether it's reducing your actual risk of a heart attack or stroke — and if side effects show up, talk to your prescriber about adjusting rather than quitting outright.
