Depletes Magnesium. This medication is commonly used for Hypertension
Research suggests that Felodipine, a type of calcium channel blocker (CCB), may increase the excretion of magnesium in the urine. This can potentially lead to magnesium deficiency. Studies have shown an increase in fractional excretion of magnesium following felodipine treatment, and the drug may also alter how magnesium moves across red blood cell membranes. Therefore supplementation with magnesium should be considered when on this therapy.

Low or depleted magnesium levels are associated with a higher likelihood of several cardiovascular problems, including arrhythmias, where people with low magnesium have been shown to have 2–4 times higher odds of these rhythm disturbances compared with those with normal levels. Low magnesium is also linked to worsening coronary artery disease, progression of heart failure, and development or aggravation of hypertension, driven by disrupted cardiac electrical stability, vascular function, and electrolyte balance. Even mild magnesium depletion may contribute to higher blood pressure over time, adding to the overall cardiovascular burden, especially in individuals with existing heart disease or multiple risk factors.
Low or depleted magnesium levels place people with diabetes and metabolic syndrome (MetSyn) at higher risk of worsening glycemic control and insulin resistance because magnesium is essential for normal glucose metabolism and beta-cell function. When magnesium is low, these metabolic pathways become less efficient, amplifying blood sugar instability, lipid abnormalities, and other MetSyn features. Even moderate depletion can accelerate type 2 diabetes and MetSyn-related complications, underscoring the need for monitoring magnesium status in these vulnerable groups.
Magnesium depletion can contribute to neurological issues like migraines, depression, seizures, and cognitive impairment by disrupting neuronal excitability, neurotransmitter balance, and NMDA receptor function. Case reports often describe severe symptoms such as tremors, encephalopathy, cerebellar ataxia, or memory problems in affected patients, which typically resolve once magnesium levels are restored. Although these effects occur less frequently than cardiovascular complications, monitoring is advisable particularly in older adults with persistent low magnesium.
