Simvastatin<\/span><\/a> (generic <\/span>Zocor<\/span><\/a>) is an oral medication approved by the Food and Drug Administration (FDA) to lower cholesterol levels. This statin is generally safe and effective in treating high cholesterol, but taking it with certain other medications, drinks, or foods may increase the risk of serious side effects like liver or muscle damage. It is important to be aware of these interactions and tell your healthcare provider and pharmacist about all of the prescriptions and supplements you\u2019re taking, especially since about 22% of people who take simvastatin also take a medication that could potentially interact with it.\u00a0<\/span><\/p>\n

Simvastatin drug interactions<\/span><\/h2>\n

Many patients with cardiovascular disease may need statins as well as other medications, especially if they have other related health conditions. However, some of those medications can affect how the body absorbs, distributes, metabolizes, and excretes statins. As such, severe side effects can occur, including myopathy (muscle weakness), <\/span>rhabdomyolysis<\/span><\/a> (breakdown of muscle tissue), and hepatic disease (liver damage).\u00a0<\/span><\/p>\n

Some types of medication are more likely to interact with simvastatin than others.\u00a0<\/span><\/p>\n

Strong CYP3A4 inhibitors<\/span><\/h3>\n

Cytochrome P450 3A4 (CYP3A4) is an enzyme that helps the body break down many medications, including simvastatin. However, some medications inhibit CYP3A4 (prevent it from working), which can cause too much simvastatin to build up in a person\u2019s bloodstream. When that happens, liver damage, muscle weakness (myopathy), and muscle breakdown (rhabdomyolysis) may occur.\u00a0<\/span><\/p>\n

Medications that significantly prevent the breakdown of simvastatin are called \u201cstrong CYP3A4 inhibitors.\u201d Your healthcare provider may choose to prescribe a different type of statin if you currently take a strong CYP3A4 inhibitor.\u00a0<\/span><\/p>\n

There are dozens of strong CYP3A4 inhibitors, including:\u00a0\u00a0\u00a0<\/span><\/p>\n
