Should I take statins?
Last updated on January 26, 2025
Overview
Statins are prescription medications that lower cholesterol by blocking its liver production, typically prescribed for high LDL levels, heart disease, or high cardiovascular risk. While they effectively reduce heart attack risk by 25-35% in most people, about 10-20% experience side effects like muscle pain, and some may see increases in other blood fats like Lp(a). Starting statins requires initial blood tests and regular monitoring, with cholesterol-lowering effects beginning within days but cardiovascular benefits taking 1-2 years to emerge. The medication is usually long-term, though alternatives exist for those who can’t tolerate them.
What are statins?
Statins are medications that lower cholesterol by inhibiting HMG-CoA reductase, an enzyme crucial for cholesterol production in the liver. By reducing low-density lipoproteins (LDL) in the blood, statins help prevent cardiovascular events like heart attacks and strokes. They also stabilize arterial plaque and have been widely prescribed since their FDA approval in 1987, starting with lovastatin. Their primary function is reducing the transport of cholesterol to tissues while having a modest effect on increasing the removal of cholesterol via high-density lipoproteins (HDL).
When do doctors prescribe statins?
Doctors typically prescribe statins based on several key risk factors: elevated LDL levels (usually above 190 mg/dL), history of cardiovascular disease, diabetes in patients aged 40-75, or a calculated 10-year cardiovascular risk greater than 7.5%. The decision also considers family history, age, blood pressure, and smoking status. Guidelines from the American College of Cardiology and American Heart Association recommend statins for primary prevention in high-risk patients and secondary prevention for those with established heart disease.
How do I get statins?
Statins require a prescription from a licensed healthcare provider. You can get them through a primary care physician, cardiologist, or other qualified medical provider after an evaluation of your cardiovascular risk factors and appropriate blood tests.
Do statins work for everyone?
For most people, statins effectively lower cholesterol and reduce cardiovascular risk. However, about 5-10% of patients show poor response to treatment, and 10-20% experience side effects like muscle pain that may limit their use. Genetic factors can influence both effectiveness and side effect susceptibility.
Multiple large clinical trials have demonstrated that statins significantly reduce cardiovascular events and mortality in both primary and secondary prevention for most people. Studies show they lower the risk of heart attacks by 25-35% and strokes by 18-30%, with benefits typically appearing within 1-2 years of starting treatment. Their effectiveness is particularly well-documented in patients with existing cardiovascular disease or multiple risk factors.
The key landmark trials supporting statin efficacy include:
• 4S (1994) – First major trial showing simvastatin reduced mortality in patients with heart disease
• WOSCOPS (1995) – Demonstrated pravastatin’s effectiveness in primary prevention
• CARE (1996) – Showed pravastatin benefit in patients with average cholesterol levels
• LIPID (1998) – Confirmed pravastatin’s mortality benefit in patients with prior heart disease
• HPS (2002) – Large study showing simvastatin benefits across wide range of patients
• JUPITER (2008) – Demonstrated rosuvastatin’s benefit in people with normal LDL but elevated inflammation
However, given how widely statins are prescribed, the number of people who experience poor response or side effects is substantial—potentially millions of patients worldwide. This fact has led to significant public skepticism about statins, with some patients and advocates questioning whether they are overprescribed and if their benefits have been overstated by pharmaceutical companies. These concerns have gained traction on social media and alternative health websites, though major medical organizations maintain that statins’ benefits outweigh their risks for most prescribed patients.
The contrarian view on statins faces a challenge in finding large, rigorous studies that definitively support skeptical positions. Critics often cite:
• DuBroff (2019) meta-analysis questioning primary prevention benefits of statins
• ALLHAT-LLT trial (2002) finding no mortality benefit in certain groups
• PROSPER study (2002) showing limited benefit of statins in elderly
However, unlike the pro-statin landmark trials, these studies tend to be smaller, focus on specific subgroups, or examine secondary outcomes. Most analyze existing data rather than conducting new randomized controlled trials.
Furthermore, while statins effectively lower LDL cholesterol by upregulating LDL receptors, they can paradoxically increase levels of Lp(a), particularly in people carrying smaller Lp(a) variants. Research suggests this may occur through increased hepatic production of apolipoprotein(a), as demonstrated by higher LPA mRNA levels in cell cultures exposed to statins. This effect is notably different from other cholesterol-lowering drugs like PCSK9 inhibitors, which reduce both LDL and Lp(a) levels.
How do statins work?
Statins work by inhibiting HMG-CoA reductase, a key enzyme in the liver’s cholesterol production pathway. This inhibition triggers several mechanisms: reduced cholesterol synthesis, increased expression of LDL receptors on liver cells, enhanced removal of LDL from blood, and reduced production of very low-density lipoproteins (VLDL). These combined effects lead to lower blood cholesterol levels, though they can paradoxically increase certain lipoproteins like Lp(a).
How long do statins take to work?
Statins begin lowering cholesterol within 2-3 days of starting treatment, with maximum effects typically seen within 4-6 weeks. The reduction in cardiovascular risk, however, develops more gradually, with clinical trials showing benefits in reducing heart attacks and strokes emerging after 1-2 years of consistent use.
What tests do I need when taking statins?
Before starting statins, doctors typically require a lipid panel and liver function tests (LFTs) as baseline measurements. During treatment, LFTs should be checked within 6-12 weeks of starting treatment and periodically thereafter. Lipid panels are usually monitored every 3-12 months to assess effectiveness. Additional tests like creatine kinase (CK) levels are ordered if muscle symptoms develop.
Would I need to take statins forever?
Yes, statins are typically prescribed as a long-term medication. Once started, they usually need to be taken indefinitely to maintain their protective effects against cardiovascular disease, as stopping them allows cholesterol levels to return to baseline within a few weeks. However, some patients may be able to reduce or stop statins if they achieve significant lifestyle changes or if their risk factors change substantially.
What are the risks of taking statins?
The main risks of statin therapy include muscle problems (myopathy) affecting 10-20% of users, ranging from mild pain to rare but serious muscle breakdown (rhabdomyolysis). Other significant risks include a small increased risk of type 2 diabetes, temporary liver enzyme elevation, and potential cognitive effects like memory issues. However, severe adverse events are rare, occurring in less than 1% of users, and regular monitoring can help identify problems early.
Building on the risks mentioned above, statin side effects can be categorized by frequency: common (>1%), less common (0.1-1%), and rare but serious (<0.1%). These percentages are approximate and individual risk varies based on factors like age, other medications, and genetic predisposition.
Common Side Effects (>1%):
• Muscle pain / weakness (10-20%)
• Increased liver enzymes (1-3%)
• Digestive issues, e.g., nausea, diarrhea (5-10%)
• Headache (2-5%)
• Fatigue (2-4%)
• Sleep problems (1-2%)
• Blood sugar elevation, including a 9% increased diabetes risk
Less Common (0.1-1%):
• Memory problems / cognitive issues (0.1-0.5%)
• Kidney problems (0.1-0.5%)
• Peripheral neuropathy (0.2-0.3%)
Rare but Serious (<0.1%):
• Rhabdomyolysis, i.e., severe muscle breakdown (0.01%)
• Severe liver injury (0.001%)
• Autoimmune myopathy (0.01-0.1%)
With what frequency do statins increase other atherogenic lipids?
Statins can increase Lp(a) levels in between approximately a quarter and a third of patients. Carriers of small apo(a) variants (i.e., less than 22 K4 repeats in their LPA gene) are particularly susceptible to this increase. In these individuals, studies showed Lp(a) levels increased from 66.4 to 97.4 mg/dL after starting statins. However, the frequency of this effect varies across populations and studies have shown mixed results.
How many people in the US take statins?
According to recent estimates, approximately 40 million U.S. adults take statins. The breakdown by age:
• Ages 20-39: ~2% (~1.5 million)

Conclusion
The complexity surrounding statins illustrates a broader challenge in modern medicine: treatments that work well for most but may harm specific subgroups due to genetic or metabolic differences. While statins remain a cornerstone of cardiovascular disease prevention, their paradoxical effects in some patients (like raising Lp(a) in those with specific genetic variants) point to the growing importance of personalized medicine. Moving forward, genetic testing and biomarker screening could help identify which patients will benefit most from statins versus alternative treatments, potentially transforming the current one-size-fits-most approach into more targeted therapy strategies.
