Drug Information

Rosuvastatin is used along with dietary changes to reduce total and LDL ("bad") cholesterol and fat levels in the blood, and to increase HDL ("good") cholesterol levels. It belongs to a class of drugs called HMG-CoA reductase inhibitors.

Summary of Interactions with Vitamins, Herbs, & Foods

Types of interactions: Beneficial Adverse Check

Replenish Depleted Nutrients

  • Coenzyme Q10

    In a group of patients beginning treatment with atorvastatin, the average concentration of coenzyme Q10 in blood plasma decreased within 14 days, and had fallen by approximately 50% after 30 days of treatment. Many doctors recommend CoQ10 supplementation to prevent the drug-induced decline in CoQ10 levels.

Reduce Side Effects

  • Coenzyme Q10

    In a preliminary study, supplementation with 100 mg of CoQ10 per day reduced the severity of muscle pain by 40% in people with muscle pain caused by a statin drug. A double-blind trial also found that CoQ10 (200 mg per day) significantly decreased drug-induced muscle symptoms in people taking statin drugs.

    However, in another double-blind trial, CoQ10 in the amount of 60 mg twice a day for one month was not more effective than a placebo for relieving muscle pain. Although the evidence is conflicting regarding whether supplementing with CoQ10 relieves statin-induced muscle symptoms, many doctors recommend CoQ10 supplementation to prevent the drug-induced decline in CoQ10 levels.

  • Creatine Monohydrate
    In a preliminary study, ten patients who had to discontinue statin drugs because of muscle-related side effects were given creatine (as creatine monohydrate) in the amount of 5 grams twice a day for five days, then 5 grams per day. Eight of the ten patients experienced no muscle symptoms upon resuming the statin drug.
  • Vitamin D
    In a preliminary trial, supplementation with vitamin D appeared to prevent muscle-related side effects in patients taking statin drugs. The amount of vitamin D used in this study was very large (up to 50,000 IU twice a week) and potentially toxic. People taking statin drugs should consult with their doctor regarding how much vitamin D can be taken.
  • Vitamin E

    Oxidative damage to LDL (“bad”) cholesterol is widely believed to contribute to heart disease. In a double-blind trial, lovastatin was found to increase oxidative damage to LDL cholesterol and vitamin E was reported to protect against such damage, though not to completely overcome the negative effect of lovastatin. This study suggests that people taking lovastatin might benefit from supplemental vitamin E.

Support Medicine

  • Fish Oil

    In a preliminary trial, taking an HMG-CoA reductase inhibitor (“statin”) for about three years significantly lowered triglyceride levels and raised levels of HDL (“good”) cholesterol in people with high cholesterol who had also been supplementing with either 900 mg or 1,800 mg of EPA for three months. The authors of the study concluded that the combination of the statin and EPA may prevent coronary heart disease better than the drug alone. Since drugs in the statin family have similar mechanisms of action, people taking any statin drug may benefit from fish oil.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Psyllium
    In one study, the addition of psyllium (10 grams per day) enhanced the cholesterol-lowering effect of lovastatin.
    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Sitostanol

    A synthetic molecule related to beta-sitosterol, sitostanol, is available in a special margarine and has been shown to lower cholesterol levels. In one study, supplementing with 1.8 grams of sitostanol per day for six weeks enhanced the cholesterol-lowering effect of various statin drugs.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Reduces Effectiveness

  • Magnesium

    A magnesium- and aluminum-containing antacid was reported to interfere with atorvastatin absorption. People can avoid this interaction by taking atorvastatin two hours before or after any aluminum/magnesium-containing antacids. Some magnesium supplements such as magnesium hydroxide are also antacids.

Potential Negative Interaction

  • Antioxidants
    In one study, daily supplementation with a combination of antioxidants (800 IU of vitamin E, 1,000 mg of vitamin C, 25 mg of beta-carotene, and 100 mcg of selenium) blocked the beneficial effect of simvastatin-plus-niacin on HDL cholesterol levels. Although there is evidence that some or all of these nutrients may help prevent heart disease, individuals taking simvastatin (or other statin drugs) who wish to take antioxidants should discuss the use of these supplements with their doctor.
    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Pomegranate

    In a case report, a man taking rosuvastatin developed severe muscle damage (rhabdomyolysis), a known side effect of rosuvastatin, after he began drinking pomegranate juice (about 6 ounces twice a week). While a cause–effect relationship was not proven, the authors of this report suggested that pomegranate may have increased the toxicity of rosuvastatin by slowing the rate at which the body broke it down.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Red Yeast Rice

    A supplement containing red yeast rice (Monascus purpureas) (Cholestin) has been shown to effectively lower cholesterol and triglycerides in people with moderately elevated levels of these blood lipids. This extract contains small amounts of naturally occurring HMG-CoA reductase inhibitors such as lovastatin and should not be used if you are currently taking a statin medication.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Explanation Required 

  • Vitamin B3 (Niacin)

    A recent blinded study showed that individuals taking both rosuvastatin and niacin had a greater increase in HDL (“good”) cholesterol and apolipoprotein A-I than did those taking rosuvastatin alone. People taking rosuvastatin might benefit from taking niacin, though they should consult with their healthcare provider before starting the supplement. When taken with niacin, some statin drugs may become more toxic so there is a possibility of an adverse interaction.

The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
