Dr Chan Po Fun [MBBS, MRCP, FRCP (UK), FAMS (Cardiology)] is a consultant cardiologist in Singapore specialising in cholesterol management and cardiovascular risk reduction.
Can I Stop My Statin Once My Cholesterol Is Normal?
This is one of the most common questions I hear in clinic:
“Doctor, my cholesterol is normal now. Can I stop my statin?”
It is a very reasonable question. And it matters, because in Singapore, cardiovascular disease remains the second leading cause of death, responsible for approximately 1 in 3 deaths annually. Getting the statin decision right, in both directions, is genuinely important.
Nobody wants to take medication unnecessarily. But the answer depends on why the statin was started in the first place.
In Singapore’s lipid management guidelines, treatment decisions are based not only on cholesterol numbers, but on a person’s overall cardiovascular risk, including age, blood pressure, diabetes, smoking, family history and other risk enhancers.
The Important Point: We Treat Risk, Not Just Cholesterol Numbers
A statin lowers LDL cholesterol, but it also helps reduce the long-term risk of heart attack and stroke.
So when your LDL becomes normal, it may mean:
Your lifestyle changes worked
The statin is working
Both are working together
If the statin is stopped, LDL cholesterol may rise again, especially if the original cause was genetic or long-standing.
When Stopping a Statin May Be Reasonable
Stopping or reducing a statin may be considered in selected patients, especially if the original risk was low.
1. You were started on a statin for mild cholesterol elevation only
For example:
No diabetes
No high blood pressure
No smoking
No known heart artery disease
No strong family history of early heart disease
LDL was only mildly elevated
In lower-risk patients, lifestyle management may be appropriate, and the need for statin treatment can be reviewed over time. Singapore guidance recommends lifestyle management for patients with lower 10-year cardiovascular risk, while considering additional “risk enhancers” before deciding on statins.
2. You made major, sustained lifestyle changes
It may be reasonable to reassess medication if you have made meaningful changes such as:
Significant weight loss
Regular exercise
Improved diet
Better blood pressure control
Stopped smoking
Improved glucose control
But this should be confirmed with repeat blood tests, not guessed.
A practical approach may be to repeat your lipid panel after a trial period and reassess your overall risk.
3. The statin was started during a temporary situation
Sometimes cholesterol rises due to reversible causes, such as:
Poor diet during a stressful period
Weight gain
Uncontrolled hypothyroidism
Certain medications
Poorly controlled diabetes
Menopause-related metabolic changes
If the underlying factor improves, your doctor may review whether long-term statin therapy is still needed.
4. You have troublesome side effects
Muscle aches are one of the most common reasons patients want to stop statins. Fear of side effects and perceived side effects are also common reasons patients discontinue statins.
But stopping is not the only option.
Your doctor may consider:
Lowering the dose
Switching to another statin
Taking it on alternate days
Adding ezetimibe
Checking CK, liver enzymes, thyroid function or vitamin D if appropriate
The aim is not to force you to take medication. The aim is to find the safest and most acceptable way to reduce your risk.
When Stopping a Statin Is Usually Risky
I would be much more cautious about stopping statins if you have:
Previous heart attack
Previous stroke or TIA
Coronary artery disease on CT scan
Stent or bypass history
Diabetes
Chronic kidney disease
High Lp(a)
Strong family history of early heart disease
Very high LDL cholesterol before treatment
In these situations, the statin is not just “for cholesterol”. It is part of long-term cardiovascular protection.
For patients who need maximally tolerated statin therapy, Singapore’s Healthier SG lipid disorder guidance notes that many would benefit from more than 50% LDL-cholesterol reduction, and non-statin add-ons such as ezetimibe may be helpful if high-intensity statins are not tolerated.
Not sure whether your statin is still right for your risk level?

Not sure if you need a statin?
What About Lp(a) and Family History?
This is especially important.
Some patients are thin, active and eat well, but still have high cardiovascular risk because of genetics.
Two important clues are:
High Lp(a)
Family history of early heart disease
In these cases, “normal cholesterol” may not mean “low risk”. The 2025 ESC dyslipidaemia update specifically highlights new data on Lp(a) as a risk modifier.
So if you have high Lp(a) or a strong family history, please do not stop your statin just because the latest LDL number looks better.
A Safe Way to Discuss Stopping Statins in Singapore
Before stopping, ask your doctor:
Why was I started on a statin?
What was my original LDL before treatment?
Do I have plaque in my heart arteries?
What is my overall cardiovascular risk?
Do I have high Lp(a) or family history?
If I stop, when should I repeat my cholesterol test?
What LDL target are we aiming for?
The Bottom Line
Stopping a statin may be reasonable if you are low risk, had only mild cholesterol elevation, have made sustained lifestyle changes, and have a clear monitoring plan.
But it may be risky if you have diabetes, heart artery plaque, previous stroke or heart attack, high Lp(a), or strong family history.
The best question is not:
“Is my cholesterol normal?”
The better question is:
“What is my long-term heart risk, and do I still need medication to reduce it?”
Never stop your statin on your own. Speak to your doctor and make a plan that is safe for your heart.

Frequently Asked Questions
Can I stop my statin once my cholesterol is normal?
In some low-risk patients, it may be possible to reduce or stop statin therapy. However, for many patients, cholesterol improves because of the medication, and stopping it may cause levels to rise again. A proper risk assessment is important before making this decision.
Is it safe to stop statins suddenly?
It is generally not recommended to stop statins abruptly without medical advice. Stopping suddenly may lead to a rebound increase in cholesterol levels and loss of cardiovascular protection.
Who needs to take statins long term?
Patients with higher cardiovascular risk, such as those with diabetes, coronary artery disease, prior stroke, high Lp(a), or strong family history, often benefit from long-term statin therapy.
What can I do instead of statins?
Lifestyle changes such as diet, exercise, and weight loss are important. In some cases, alternative medications like ezetimibe or newer therapies may be considered, especially if statins are not well tolerated.
When should I see a doctor about stopping statins?
You should consult a doctor if you are considering stopping statins, experiencing side effects, or want a personalised assessment of your cardiovascular risk.
Can women stop statins during menopause?
Menopause is actually a time of increased cardiovascular risk —
cholesterol levels, blood pressure, and vessel function can all
change as oestrogen levels decline. For most women, this makes
continuing statin therapy more important during and after menopause,
not less. Any decision to stop should be made with a full review
of cardiovascular risk at that life stage.
My muscles ache on statins. Should I just stop?
Muscle ache is one of the most common reasons patients want to
stop, but it is not a reason to stop without exploring alternatives
first. Switching to a different statin, lowering the dose, or trying
alternate-day dosing resolves the problem for many patients. There
are also non-statin options that lower LDL effectively. Speak to
your cardiologist before stopping.
If I stop my statin, how quickly will my cholesterol go back up?
In most patients, LDL cholesterol returns to its pre-treatment
level within 4 to 8 weeks of stopping a statin. This is why
stopping without a monitoring plan is not advisable. A repeat
blood test within 6 to 12 weeks is important to confirm what
happens to your levels.
