Taking magnesium (specifically as an antacid) at the same time as ezetimibe may slightly lower the amount of ezetimibe your body absorbs. However, this effect is very small and is not expected to change how well your cholesterol is managed.

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.
What you should do
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.

Important precautions
Enfermedad hepática
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.
Food and drink warnings
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.

Can I take Bisoprolol and Trimbow pmdi // pressurised inhalation together?
Bisoprolol and Trimbow (which contains formoterol) work in opposite ways on the airways. Bisoprolol may cause the airways to narrow, making it harder to breathe and potentially triggering asthma or COPD symptoms. It also makes the formoterol in the Trimbow inhaler less effective at opening your airways.
Tratamiento y medicación
Can I take Evana heavy period relief and Mefenamic acid together?
Taking these two medicines together significantly increases your risk of serious stomach problems, such as stomach ulcers, bleeding, or irritation of the stomach lining. It can also put extra strain on your kidneys.
