Statin therapy can lead to mild increase in liver enzymes but this can be managed by lowering the dose or changing to another brand.
Randomised controlled trials have shown that there was no support for an adverse effect of statin therapy on the kidney; instead, results indicated that statin therapy might slow the progression of renal impairment3.
Health supplements are currently not subject to pharmaceutical regulations. Unlike medicines prescribed by the doctors, health supplements generally do not require to go through stringent clinical trial requirements and approval. They may vary in dose strength and contain ingredients that may not necessarily be identified.
“Natural” supplements may not necessarily mean that they are safe for every individual, as some supplements may cause harm instead, depending on the person’s health condition and whether the supplements are taken with any other medicines.
MYTH 4: Statins cause diabetes.
FACT: Statins are associated with a small increase in risk of diabetes, mainly in those who are at risk of diabetes.
It is important to note that the benefits of reducing cardiovascular risk with statins outweigh the increased risk of
diabetes. In addition, patients with diabetes also benefit greatly from statins, which reduce their risk of heart attack, stroke and death.
MYTH 5: Statins cause memory loss and confusion.
FACT: Evidence has shown that statins are neither associated with memory loss nor have adverse effects on cognitive function4,5.
There were studies that found that statins may have a protective and symptomatic benefit in
dementia and cognitive changes, and can
prevent dementia, especially with long-term use6.
MYTH 6: Being intolerant to statins means I will never be able to take statins.
FACT: Most people can tolerate statins either by changing the type of statins or by staggering their doses.
Patients should consult their doctors on the treatment options available.
MYTH 7: I have never been told I have high cholesterol, so I will not need statins.
FACT: Studies have shown that patients who took statins have lowered their LDL cholesterol and reduced their overall risk of cardiovascular events, regardless of their cholesterol concentrations1.
High-intensity statins regimen is warranted in patients with elevated risk of cardiovascular events even if they are presented with average or below average LDL cholesterol.
MYTH 8: Does changing my diet work as well as taking statins?
FACT: A healthy diet is very important in helping to prevent a heart attack and stroke. With both statins and diet modification7, the risk of heart attack/stroke and cholesterol can be reduced.
Statins do not just lower cholesterol level. They also reduce the risk of plaques breaking off in the blood vessels, thereby reducing risk of causing a heart attack or stroke.
The claims on the side effects of statins might have resulted in the under-utilisation among those who are at increased risk of cardiovascular events.
It is therefore important to always seek medical advice from doctors or reliable sources to address any concerns.
