Can I take Amlopidine and Magnesium together?

Why this happens

Both amlodipine and magnesium work by relaxing the muscles in your blood vessels and heart. Amlodipine is a 'calcium channel blocker', and magnesium acts as a natural calcium blocker. When used together, they can have an 'additive effect', meaning they strengthen each other's ability to lower blood pressure and slow the heart.

It is usually safe to take these together, but you should monitor your blood pressure regularly. If you feel dizzy, especially when standing up, or notice your heart rate is unusually slow, speak to your GP. If you are taking high-dose magnesium supplements or using magnesium intravenously, your doctor may need to adjust your amlodipine dose.

Kidney disease

If you have severe kidney impairment, your body cannot remove excess magnesium. This can lead to dangerously high levels in the blood, affecting your heart rhythm and breathing.

Dairy products (Milk, Cheese, Yoghurt)

Dairy products are high in calcium. Calcium can compete with magnesium for absorption in the gut. If you take a magnesium supplement, try to take it at least 2 hours apart from eating large amounts of dairy to ensure you get the full benefit of the mineral.

Alcohol

Alcohol can lower your blood pressure. Taking amlodipine with alcohol may cause you to feel dizzy, lightheaded, or faint. Additionally, chronic alcohol consumption can cause the body to lose magnesium through urine, potentially making a magnesium deficiency worse.
