Statins are a type of medication people take to lower cholesterol and treat heart disease. However, they may interact with compounds in grapefruit juice. In some cases, this interaction can be dangerous.Certain molecules occurring naturally in grapefruit juice may increase the level of statins in a person’s blood, which can amplify their effects.However, drinking a small glass of grapefruit juice may not have severe effects. But a person taking statins should always speak with a healthcare provider before consuming grapefruit or grapefruit juice.This article explores how grapefruit and statins can interact, which statins may interact most, and the risks and side effects a person may experience.Grapefruit and grapefruit juice can interact with some statins, leading to potentially dangerous results.Essentially, compounds in grapefruit prevent the body from metabolizing statins normally, which increases their concentration in a person’s blood.Normally, when a person consumes statins without grapefruit juice, the enzyme CYP3A breaks them down within the intestines and liver. This process normally lowers the amount of statins reaching the bloodstream.However, furanocoumarins, compounds that occur naturally in grapefruit, deactivate this enzyme, preventing it from breaking down statins. Therefore, the body absorbs more statins than normal from the gut into the bloodstream.According to one review by the research team that discovered the grapefruit-statin interaction, more than 85 drugs may interact with these compounds in grapefruit — not just statins.In addition, other citrus fruits may contain compounds with similar interactions. These include:Seville orangeslimespomelosHowever, some varieties of citrus do not contain these interacting compounds, including navel oranges.A person taking statins can ask a healthcare provider what citrus fruits to avoid.People taking statins may wish to know whether the type they are taking interacts more or less with grapefruit juice.Not all statin medications are the same in terms of their interaction with grapefruit.When a person takes certain statins with grapefruit, their blood concentrations of the drug can become several times higher than the normal concentrations of others taking statins.Statins that interact moreThe following statins tend to interact more with the furanocoumarins in grapefruit juice:atorvastatin (Lipitor)lovastatin (Mevacor)simvastatin (Zocor)Statins that interact lessThese statin medications tend to interact less with grapefruit juice:fluvastatin (Lescol)pitavastatin (Livalo)pravastatin (Pravachol)rosuvastatin (Crestor)Consuming grapefruit or grapefruit juice when taking statins comes with a rare but serious risk of rhabdomyolysis.This condition affects less than 0.1% of people taking statins. It can occur when statin levels become too high in the blood.Characteristics of rhabdomyolysis involve damage to the body’s skeletal muscle tissue. This can cause muscle cells to leak their contents into the bloodstream, leading to elevated levels of protein in the blood.Complications of rhabdomyolysis include: acute kidney failurecompartment syndromeirregular heartbeatelectrolyte abnormalitiesThere are three main symptoms a person with rhabdomyolysis may experience:weaknesssore muscles, or myalgiatea-colored urineHowever, people with this condition
