Statins medication helps lower bad cholesterol to reduce the risk of heart attack and stroke, though some patients worry about potential side effects.

How Does Statins Medication Work?

These drugs block a specific enzyme in the liver that the body needs to produce cholesterol. By reducing the amount of LDL (bad) cholesterol, these medications prevent the buildup of plaque in the arteries. This prevents arteries from narrowing or hardening, which reduces the likelihood of blood clots that cause strokes or heart attacks.

Depending on the type, these drugs can lower bad cholesterol by 25% to 50%. They also help lower triglycerides and increase HDL (good) cholesterol, which carries bad cholesterol away from the blood and back to the liver for removal.

Common and Rare Statins Side Effects

Most people tolerate these drugs well, but some experience adverse reactions.

Common issues: These include headaches, dizziness, nausea, skin flushing, and digestive problems like bloating, gas, or constipation.
Muscle issues: Aches, tenderness, and weakness are frequent complaints. While clinical trials showed this in about 3% of people, real-world data suggests up to 30% of users report muscle pain.
Rare risks: Liver inflammation and glucose intolerance (affecting about 5 in 1,000 people) are uncommon.

Regarding the link between statins and dementia, research indicates that these drugs do not cause cognitive deficits. In fact, by preventing vascular disease, they may help mitigate the progression of dementia.

Who Is at Higher Risk for Side Effects?

Certain factors can increase the likelihood of experiencing muscle pain or statin intolerance:

Age 80 or older.
Being female or of Asian descent.
Having pre-existing kidney, liver, or thyroid disease.
Using high-dose therapy.
Taking certain medications, such as fibrates, HIV drugs, or macrolide antibiotics.
Consuming excessive amounts of grapefruit juice.

Managing Side Effects and Alternatives

If you experience muscle pain, do not stop your medication without consulting a provider. Your doctor may suggest:

A “statin vacation”: Stopping the drug for three to four weeks.
Dose adjustments: Lowering the dose or taking the pill every other day.
Switching drugs: Trying a different type of statin.
Non-statin options: Using alternatives like Ezetimibe, PCSK9 inhibitors, or bile acid sequestrants.

FAQ

What is statins medication used for?

It is used to lower LDL cholesterol and total cholesterol levels to prevent cardiovascular events like heart attacks and strokes.

Can I use diet and exercise instead?

While a heart-healthy diet helps, it is often not enough to significantly lower cholesterol for people with genetic issues or those who have already had a cardiovascular event. Doctors use risk calculators to determine if medication is necessary; generally, if the 10-year risk of an event is over 5%, medication is recommended.

Are these drugs overprescribed?

Evidence suggests they may actually be underprescribed, as many people who could benefit from the therapy are not receiving it.

What happens if I don’t take them?

Avoiding the medication when indicated can increase the risk of heart attack or stroke. On average, these drugs reduce that risk by 25% to 35%.

When to See a Doctor

Contact your healthcare provider immediately if you notice:

Severe, unexplained muscle pain, cramps, or weakness.
Signs of liver inflammation, such as flu-like symptoms.
Severe stomach pain.
Any new symptoms after starting a new dose or a new medication.
