Preventive Cardiology: Statins
Commonly Prescribed Statins
Statins are primarily prescribed for:
If you already have cardiovascular disease, your doctor may recommend statins to reduce your risk of having a heart attack
. Statin therapy may also be prescribed if you fall within a specific risk range for developing cardiovascular disease within 10-years. The risk can be assessed based on your cholesterol numbers and other risk factors. It can be done during a regular physical exam.
Mechanism for How It Works
HMG-CoA reductase is an enzyme that helps your body make cholesterol. Statins help to block this enzyme, which in turn causes your body to make less cholesterol. When you make less cholesterol, your liver makes more LDL receptors, which attract LDL particles in the blood. This reduces the amount of LDL ("bad") cholesterol in your bloodstream. Lower LDL cholesterol levels also tend to lead to lower levels of triglycerides and higher HDL (“good”) cholesterol levels in the blood. Statins have anti-inflammatory effects on blood vessels which help reduce the formation of fatty plaque on blood vessel walls.
Statins can interact with many medications. Below are some examples. But, you should talk to your doctor and pharmacist about the specific medications that you are taking.
- Protease inhibitors to treat HIV, such as indinavir, nelfinavir, ritonavir, saquinavir
Statins can interact with certain foods, herbs, and supplements. Here are examples of potential interactions:
—may increase the absorption of most statins, allowing potentially excessive levels to build up in the bloodstream
Chaparral, comfrey, and coltsfoot—may increase the risk of liver problems
St. John’s wort—may decrease blood levels of some statins
possibly increases the risk of developing a potentially fatal condition called
Red yeast rice—contains a mixture of statins and should not be combined with statin drugs
If you would like to take herbs or supplements while taking a statin, check with your doctor first.
Other Potential Concerns
These conditions can affect how your body uses statins:
- Allergy or intolerance to statins or allergies to other substances, including food
Obesity—can make statins less effective
- Positive changes in diet and exercise—may need a lower dose
If you have any of the following conditions, tell your doctor before you are prescribed statins:
Alcohol use disorder
- Liver disease
- Organ transplant and take medication to prevent transplant rejection
- Recent major surgery
- Pregnant or breastfeeding—Statins are not recommended in pregnant or nursing women.
Common Side Effects
More common side effects include:
- Upset stomach
- Abdominal pain
- Flu-like symptoms
- Muscle pain
- Skin rash
Less Common Side Effects
Less common, but more serious side effects include:
- Take only the amount of statin ordered by your doctor
- Do not stop taking this medication without first checking with your doctor
- Tell your doctor or dentist about taking this medication before having any kind of surgery, dental procedure, or emergency treatment
