Which Drugs Can Raise Your Cholesterol Levels?

Andrew Soundarajan

Some of the medications you are taking for other medical conditions, such as high blood pressure or hormonal treatments – may adversely affect your lipid levels. This could include increasing your LDL and triglyceride levels or lowering your HDL cholesterol. This may be bothersome if you have never had to worry about high cholesterol before. Additionally, if you are currently on medications to lower your cholesterol, you might notice that your therapy may need to be adjusted.

Although this is not an inclusive list, the drugs listed below are the more commonly used medications that could potentially affect your lipid levels. You should always disclose to your healthcare provider the medications that you are taking, so he or she can rule out whether or not any medications or natural products are adversely affecting your health:


Prednisone is a glucocorticoid that is used to reduce the swelling, warmth, and tenderness associated with many inflammatory conditions. Despite the relief they may give to you, they can raise triglycerides, LDL cholesterol levels, and HDL cholesterol levels. It doesn't take long to see a substantial rise in cholesterol levels: Some studies showed that patients had higher cholesterol levels within two weeks of treatment.

Beta Blockers

Beta blockers are medications that are normally prescribed to treat high blood pressure. Despite the significant advantages, they offer in treating several forms of heart disease, beta blockers also have been noted to decrease HDL levels and elevate triglyceride levels. In most cases, however, these lipid changes have been very small. It is important to note that not all beta blockers have this effect. The following beta-blockers have been noted to slightly alter lipid profiles:

  • Atenolol (Tenormin®)
  • Bisoprolol (Zebeta®)
  • Metoprolol (Toprol®, Lopressor®)
  • Nadolol (Corgard ®)
  • Propanolol (Inderal ®)

Beta-blockers not only help lower blood pressure, they also are instrumental in prolonging the survival of individuals with active heart disease (such as congestive heart failure and previous heart attack). Therefore, even if slight alterations of your lipids are observed, it is very important that beta blockers are not discontinued.


Amiodarone is a drug used to treat a variety of heart arrhythmias and is associated with a wide range of side effects. One of the smaller side effects is related to high cholesterol. Amiodarone mainly raises LDL cholesterol levels but does not appear to have an effect on HDL cholesterol or triglyceride levels.


Estrogen is a female sex hormone found in female hormonal birth control and in other forms of hormone replacement therapy. For many years, estrogen had been considered "cardioprotective," thus promoting a healthy heart. This is mainly due to its ability to raise HDL levels. This caused many post-menopausal women taking hormone replacement therapy to help their heart. However, recent studies have found that it does not protect against heart disease after menopause. The mechanism by which it causes heart attacks is unknown. Additionally, estrogens may also increase triglyceride levels.


Progestin is a form of progesterone, another female sex hormone, which is used in oral contraceptives and hormone replacement therapy alone or in combination with estrogen. Higher levels of progestin have been associated with lower HDL levels. In combination with estrogen, progestin may cancel out the healthy effect estrogen has in raising HDL levels.

Anabolic Steroids

Anabolic steroids include testosterone, the male sex hormone that is used to treat delayed puberty in boys and some forms of impotence. It is also used illegally to build muscle mass. These drugs raise LDL levels and lower HDL levels. The detrimental effects this drug has towards cholesterol levels are more noticeable in the oral medications in comparison to the injectable medications.


Cyclosporine (Sandimmune ®, Neoral®, Gengraf®) is a drug used to suppress the immune system. It is commonly used after an organ transplant in order to prevent rejection. However, it may also be used to treat rheumatoid arthritis and psoriasis. Studies have shown that cyclosporine raises LDL cholesterol levels.

Protease Inhibitors

Protease inhibitors are used to treat human immunodeficiency virus (HIV). Although the mechanism by which these drugs raise cholesterol levels is not known, they appear to especially raise triglyceride levels and lower HDL cholesterol levels. Fibrates and statins are sometimes used to lower triglycerides and increase HDL levels in individuals taking these medications.


Diuretics are used to treat high blood pressure and water retention. There are two types of diuretics that cause increased cholesterol levels:

  • Thiazide diuretics (including hydrochlorothiazide, chlorothiazide, metolazone)
  • Loop diuretics (including furosemide, torsemide, bumetanide)

Thiazide diuretics cause a temporary increase in total cholesterol levels, triglyceride levels, and LDL cholesterol levels. HDL cholesterol levels are not typically affected. This increase may range between 5 to 10 milligrams per deciliter. Currently, indapamide is the only thiazide diuretic that has not been shown to adversely affect lipid levels. Loop diuretics share the same pattern as thiazide diuretics; however, some of these drugs have shown a slight decrease in HDL cholesterol. Since diuretics are very important in the treatment of lowering blood pressure, your healthcare provider may also place you on a low-fat diet while you are on this medication.

If you have high cholesterol levels and are taking a medication that could potentially raise your lipid levels further, your healthcare provider may want to monitor your blood periodically to make sure that your lipid levels are not too high. In some cases, the adverse effect on lipids may be only temporary. However, if they persist to be high after treatment starts, your healthcare provider may decide to add or modify your cholesterol-lowering therapy.
