Depending on the cause, the medication used to treat foot cramps varies. In patients with hypoparathyroidism and vitamin D deficiency, attention should be paid to vitamin D supplementation, and those with chronic renal failure need oral or intravenous sodium bicarbonate to correct acidosis. However, it is important to note that foot cramps can also be caused by non-disease factors, such as exertion and prolonged holding the same position, and only patients with a confirmed diagnosis may need to take medication.
