Can I take Ezetimibe and Magnesium together?

Why this happens

Magnesium-containing antacids can physically bind to ezetimibe in the digestive tract or change the acidity of the stomach, which slightly reduces the rate at which the medicine enters the bloodstream.

You can take these together, but to be safe, you may wish to separate the doses by 2 to 4 hours. If you are taking magnesium as a daily supplement rather than an antacid, the interaction is even less likely to be significant. Continue to have your cholesterol levels monitored by your doctor as usual.

Liver disease

You must not take ezetimibe if you have moderate or severe liver disease, as it can worsen your condition. Contact your doctor immediately if you develop yellowing of the skin or eyes.

Severe kidney impairment

If you have severe kidney disease, you must avoid magnesium supplements unless specifically directed by a specialist. Your kidneys may not be able to remove excess magnesium, leading to dangerously high levels in the blood.

Unexplained muscle pain - ezetimibe

You must contact your doctor immediately if you experience unexplained muscle pain, tenderness, or weakness. While rare, this can be a sign of serious muscle breakdown, especially if taken alongside a statin.

Dairy products and calcium-rich foods

High doses of calcium from dairy or supplements can compete with magnesium for absorption. If you are taking large amounts of both, it is best to space them at least 2 hours apart.

Alcohol

Excessive alcohol consumption can increase the amount of magnesium your body loses through urine, potentially making the supplement less effective over time.

It is best to avoid or strictly limit alcohol while taking ezetimibe. Both alcohol and ezetimibe can affect your liver; combining them may increase the risk of liver damage or inflammation. If you have a history of liver disease, you should be particularly cautious.

Caffeine (Coffee, Tea, Energy drinks)

It is best to limit caffeine intake around the time you take magnesium. Like alcohol, caffeine has a mild diuretic effect and can increase the excretion of magnesium through the kidneys.

High-fibre foods and Phytic Acid

Foods very high in fibre or phytic acid (such as whole-grain cereals, bran, beans, and nuts) can interfere with the absorption of magnesium. If you eat a very high-fibre meal, try to take your magnesium supplement at a different time of day.
