People with advanced kidney disease sometimes must undergo dialysis, during which waste is filtered from the blood. Certain drugs may delay the need for dialysis.

Because high blood pressure can damage the kidneys, many patients with chronic kidney disease take drugs to lower their blood pressure. These patients might find it more beneficial to take their drugs before bed.

It's been known that low blood pressure while undergoing kidney dialysis is linked to some nasty side effects. Now the risk of blood clots has been added to that expanding list.
