Atorvastatin and Statins: Cholesterol Medicine Guide

6 min read · Medicines · By the Asthra Health Care team

What statins are used for

Statins are prescription medicines that lower cholesterol, especially LDL, often called bad cholesterol. Atorvastatin and rosuvastatin are the most widely used in India; others include simvastatin and pravastatin. Doctors prescribe them to people who have had a heart attack, stroke or stent, and to those at high risk because of diabetes, high blood pressure, smoking, family history or very high cholesterol.

Heart disease often appears at a younger age in Indian adults, and many people have high cholesterol without any symptoms. Statins reduce the chance of future heart attacks and strokes. They work alongside, not instead of, a healthy diet and regular activity.

• After a heart attack, stroke, angioplasty or bypass
• Diabetes with other heart risk factors
• High LDL cholesterol, including inherited forms
• High overall heart risk as judged by a doctor

How atorvastatin and statins work

Most cholesterol in the blood is made by the liver. Statins block an enzyme the liver needs to make cholesterol. When the liver makes less, it pulls more LDL cholesterol out of the blood, so blood levels fall. The effect is strongest on LDL cholesterol, but statins can also modestly lower triglycerides and slightly raise HDL, the helpful form of cholesterol.

Statins also help steady the fatty plaques inside arteries, making them less likely to burst and cause a clot. This is why doctors often continue statins even when cholesterol numbers look normal, especially after a heart attack or stroke. Blood levels usually improve within a few weeks of regular use.

Atorvastatin and statins side effects: common and serious

Most people take statins without trouble. Common side effects include muscle aches, tiredness, headache, constipation, nausea or wind. Muscle aches are often mild, and some aches blamed on statins turn out to have other causes, so discuss them with your doctor rather than stopping.

Serious side effects are rare. They include severe muscle damage with muscle pain, weakness and dark urine, which needs urgent care, and liver inflammation. Statins can slightly raise blood sugar and may bring forward a diabetes diagnosis in people already at risk, but doctors agree the heart benefits usually outweigh this.

Who should avoid them or take extra care

Statins must not be used in pregnancy or while breastfeeding, so women who could become pregnant should discuss this with their doctor and stop only on medical advice if pregnancy is planned. People with active liver disease should not take them. Those with kidney disease, an underactive thyroid, heavy alcohol use or older age may have a higher risk of muscle side effects.

Statins are only on a doctor's prescription; never start or stop them on your own. Children are prescribed statins only for inherited high cholesterol under specialist care. Before starting, your doctor may check liver tests and sometimes thyroid function, since an underactive thyroid can both raise cholesterol and increase muscle side effects. Let your doctor know about any past muscle problems with medicines.

Atorvastatin and statins interactions to know

Some medicines raise statin levels and increase the risk of muscle damage. These include clarithromycin and erythromycin, certain antifungals such as itraconazole and ketoconazole, some HIV and hepatitis C medicines, ciclosporin, gemfibrozil and, for some statins, amlodipine, diltiazem and verapamil. Colchicine used for gout also adds to muscle risk.

Large amounts of grapefruit juice can raise levels of atorvastatin and simvastatin. Doctors sometimes combine a statin with ezetimibe or fenofibrate to lower cholesterol further, but this is their decision. Always tell every doctor and pharmacist that you take a statin, especially when a new antibiotic is started.

Practical tips for using atorvastatin and statins

Take your statin at the same time each day as prescribed. Some statins are best taken in the evening, while atorvastatin and rosuvastatin can be taken at any time; follow your doctor's or pharmacist's advice. Keep taking it long-term, as the benefit comes from steady use over years.

Eat more vegetables, fruit, whole grains, dal and nuts, and cut down on ghee, vanaspati, fried snacks, red meat and bakery items. Walk or exercise most days, stop smoking and keep a healthy weight. Get a lipid profile and other blood tests as your doctor advises.

When to talk to your doctor about atorvastatin and statins

Tell your doctor if you have muscle aches, weakness or unusual tiredness, rather than stopping the statin. Seek urgent care for severe muscle pain with dark urine, yellowing of the eyes, or any chest pain or stroke symptoms. Ask your doctor or pharmacist if you have any concerns about your cholesterol medicine.
