Proton Pump Inhibitor Induced Hypomagnesemia Causing Seizures: A Rare Adverse Effect of a Commonly Used Medication.

Hypomagnesemia is defined as serum magnesium levels less than 0.7mmol/L and can result in a plethora of symptoms ranging from mild gastrointestinal symptoms to serious conditions such as cardiac arrhythmias and neurological complications. When considering the etiological factors, drug-induced hypomagnesemia is highlighted because commonly used medications such as proton pump inhibitors (PPIs), aminoglycoside antibiotics, and loop and thiazide diuretics can cause low magnesium levels.
