Too much potassium in your blood, a condition called hyperkalemia, can happen suddenly or because of an ongoing condition like kidney disease. But hyperkalemia can affect your heart and other parts of your body, so it’s important to treat it.
These medications include:
- IV insulin and glucose
- IV calcium
- IV sodium bicarbonate
- Inhaled albuterol
They start working in minutes by shifting potassium out of the blood and into cells.
People with very high blood potassium levels may also need dialysis, which uses a special machine to filter the potassium from your blood.
Even if hyperkalemia isn’t a crisis, you still need to get your potassium levels down.
Some medications lower potassium slowly, including:
- Water pills (diuretics), which rid the body of extra fluids and remove potassium through urine
- Sodium bicarbonate, which temporarily shifts potassium into body cells
- Albuterol, which raises blood insulin levels and shifts potassium into body cells
- Sodium polystyrene sulfonate (Kayexalate), which removes potassium through your intestines before it’s absorbed
- Patiromer (Veltassa), which binds to potassium in the intestines
- Sodium zirconium cyclosilicate (Lokelma), which binds to potassium in the intestines
Adjusting Other Medications, Diet
Your doctor will look at whether you need to stop taking other medications in order to lower your blood potassium levels, or adjust how much you take. That happens because these drugs contribute to higher potassium.
These medications include:
- NSAIDs (nonsteroidal anti-inflammatory drugs) such as the pain relievers aspirin, ibuprofen, and naproxen
- High blood pressure drugs. Some can block a hormone that controls potassium levels.
- Herbal supplements. Ask your doctor about which ones might be a hidden source of potassium.
- Potassium supplements
Too much potassium in foods can also contribute to higher levels in your blood if your kidneys don’t work well. So your doctor will ask you about what you eat and drink, and then give you advice on what things you may need to cut back on because they have a lot of potassium.
Your kidneys help control the balance of potassium in your body, and if they don’t work properly they can’t do that important job. So you might need dialysis to treat your kidney disease -- which also treats hyperkalemia.
