Get K-dur Online

K-Dur is a prescription extended-release potassium chloride tablet used to treat hypokalemia, which is a condition where blood potassium levels are too low. It is also used to prevent potassium depletion in patients taking medications such as loop or thiazide diuretics that can cause potassium loss.

K-Dur works by delivering potassium chloride slowly over time through an extended-release formulation. This replenishes the body's potassium stores and helps maintain the electrolyte balance required for normal heart rhythm, nerve signaling, and muscle contraction.

K-Dur tablets should be taken whole with a full glass of water, generally with food or immediately after a meal to reduce stomach upset. Do not crush, chew, or dissolve the tablets. Follow your physician's dosing instructions carefully, as the dose is based on your potassium levels and individual needs.

The most common side effects include nausea, vomiting, stomach discomfort, diarrhea, and gas. Taking K-Dur with food usually helps reduce gastrointestinal symptoms. Contact your provider if you experience severe stomach pain, difficulty swallowing, or signs of high potassium such as weakness or irregular heartbeat.

K-Dur should not be used by people with hyperkalemia (high blood potassium levels), severe kidney disease that limits potassium excretion, or conditions that cause reduced esophageal or gastrointestinal motility. Your physician will review your medical history and kidney function before prescribing this medication.

Yes. K-Dur can interact with potassium-sparing diuretics such as spironolactone or amiloride, ACE inhibitors, angiotensin receptor blockers, and certain heart medications. These combinations can raise potassium to dangerous levels. Always provide your physician with a complete list of your current medications before starting K-Dur.
