Medication
SALINE HYDRATION-Initial therapy of severe hypercalcemia includes the simultaneous administration of saline, calcitonin, and a bisphosphonate (see 'Severe hypercalcemia' above). Isotonic saline corrects possible volume depletion due to hypercalcemia-induced urinary salt wasting and, in some cases, vomiting.
Procedures
Prednisone. If your hypercalcemia is caused by high levels of vitamin D, short-term use of steroid pills such as prednisone are usually helpful. IV fluids and diuretics.

What is the initial therapy for hypercalcemia?
Calcium gluconate should be used as a first-line agent in patients with EKG changes or severe hyperkalemia to protect cardiomyocytes. Insulin and glucose combination is the fastest acting drug that shifts potassium into the cells. B-agonists can be used in addition to insulin to decrease plasma potassium levels.
How do you treat hypercalcemia with prednisone?
Which medications are used in the treatment of hypercalcemia in renal failure?
What is the first line treatment for hyperkalemia?
What is the most common treatment for hypercalcemia?
Although bisphosphonates are most commonly used to treat established hypercalcemia, they have also been given to prevent hypercalcemia and adverse skeletal events, particularly in patients with metastatic cancer to bone.
What is the first step in the management of acute hypercalcemia?
The initial step in the care of severely hypercalcemic patients is hydration and forced calciuresis. Because most of these patients are profoundly dehydrated, 0.9 normal saline is the crystalloid of choice for rehydration. A loop diuretic (eg, furosemide) may be used with hydration to increase calcium excretion.
What is the most common cause of hypercalcemia?
Hypercalcemia is caused by: Overactive parathyroid glands (hyperparathyroidism). This most common cause of hypercalcemia can stem from a small, noncancerous (benign) tumor or enlargement of one or more of the four parathyroid glands. Cancer.
How do I lower my calcium levels?
Excessive calcium levels in the blood (hypercalcemia) usually occurs as a result of other conditions....Often the doctor may tell you calcium levels can be lowered if you:Drink more water.Switch to a non-thiazide diuretic or blood pressure medicine.Stop calcium-rich antacid tablets.Stop calcium supplements.
How do doctors treat high calcium?
Possible treatments include intravenous fluids and medications such as calcitonin or bisphosphonates. If hypercalcemia is due to overactive parathyroid glands, too much vitamin D, or another health condition, the doctor will also treat the condition responsible.
What IV is used for hypercalcemia?
Initial therapy of severe hypercalcemia includes the simultaneous administration of intravenous (IV) isotonic saline, subcutaneous calcitonin, and a bisphosphonate (typically, IV zoledronic acid [ZA]) (table 1).
What medications can lower calcium levels?
Medications that Can Cause Low Calcium LevelsBisphosphonates: Bisphosphonates are medications for osteoporosis that prevent bones from leaking calcium, which means less calcium ends up in the bloodstream. ... Prolia: Prolia is an injection given once every six months to treat osteoporosis.More items...•
What is a dangerously high calcium level?
Your blood calcium level would be considered high if it surpasses the upper limit of the normal range, meaning it is greater than 10.3 mg/dl.
What is considered severe hypercalcemia?
Normal ionized calcium levels are 4 to 5.6 mg per dL (1 to 1.4 mmol per L). Hypercalcemia is considered mild if the total serum calcium level is between 10.5 and 12 mg per dL (2.63 and 3 mmol per L). Levels higher than 14 mg per dL (3.5 mmol per L) can be life threatening.
Does Lasix lower calcium levels?
The most commonly used diuretic, furosemide (Lasix®), causes the kidneys to produce more urine. As a result, the amount of free water in the body is reduced. Along with an increase in urine volume, furosemide causes loss of calcium, sodium and potassium.
Which of the following diuretics should be used for hypercalcemia patients?
A loop diuretic (eg, furosemide) may be used with hydration to increase calcium excretion. This may also prevent volume overload during therapy. In contrast to loop diuretics, avoid thiazide diuretics because they increase the reabsorption of calcium.
What happens if high calcium goes untreated?
If left untreated, hypercalcemia can lead to serious complications. For example, if the bones continue to release calcium into the blood, osteoporosis, a bone-thinning disease, can result. If urine contains too much calcium, crystals may form in the kidneys. Over time, these crystals may combine to form kidney stones.
What is the treatment for hypercalcemia?
When the tumor is no longer amenable to surgical intervention, treatment becomes focused on the control of hypercalcemia with medical therapy, which can include bisphosphonates, calcimimetic agents, or denosumab. (See "Parathyroid carcinoma", section on 'Treatment' .)
How often can you take salmon calcitonin?
Salmon calcitonin (4 international units/kg) is usually administered intramuscularly or subcutaneously every 12 hours; doses can be increased up to 6 to 8 international units/kg every six hours. Nasal application of calcitonin is not efficacious for treatment of hypercalcemia [ 12 ].
What is the recommended serum calcium level for hemodialysis?
Hemodialysis should be considered, in addition to the above treatments, in patients who have serum calcium concentrations in the range of 18 to 20 mg/dL (4.5 to 5 mmol/L) and neurologic symptoms but a stable circulation or in those with severe hypercalcemia complicated by renal failure. (See 'Dialysis' below.)
How often can you repeat calcitonin?
If a hypocalcemic response is noted, then the patient is calcitonin sensitive and the calcitonin can be repeated every 6 to 12 hours (4 to 8 international units/kg). Patients may develop tachyphylaxis to calcitonin after 24 to 48 hours, so therapy is usually limited to this time period and then discontinued.
How long does it take for prednisone to lower calcium levels?
In such patients, glucocorticoids (eg, prednisone in a dose of 20 to 40 mg/day) will usually reduce serum calcium concentrations within two to five days by decreasing calcitriol production by the activated mononuclear cells in the lung and lymph nodes. (See "Hypercalcemia in granulomatous diseases" .)
Is hypercalcemia a clinical manifestation?
Hypercalcemia may be associated with a spectrum of clinical manifestations, ranging from few or no symptoms in patients with mild chronic hypercalcemia to severe obtundation and coma (see "Clinical manifestations of hypercalcemia" ).
How much water should I drink to prevent nephrolithiasis?
Adequate hydration (at least six to eight glasses of water per day) is recommended to minimize the risk of nephrolithiasis. Additional therapy depends mostly upon the cause of the hypercalcemia. (See 'Disease-specific approach' below.)
What causes hypercalcemia?
Severe hypercalcemia is a potentially life-threatening complication of several diseases. Most commonly it is caused by cancers that enhance bone resorption. Impaired renal calcium excretion resulting from a combination of volume contraction and calcium-induced renal injury (nephrocalcinosis) plays a critical role in the genesis and aggravation ...
How long does it take for calcium to be reduced?
One of these agents in combination with volume expansion can reduce serum calcium concentrations to near normal in most patients within 3 to 6 days.
Can narcotics raise calcium levels?
Sedatives and narcotic analgesics, by reducing activity and oral intake, can raise serum calcium levels. In the future it may be possible to predict which patients with cancer are likely to develop accelerated local tumor-mediated or humorally mediated osteolysis.
Is hypercalcemia asymptomatic?
Patients with mild to moderate hypercalcemia may be asymptomatic. Therapy in these patients should be directed at the primary disease as well as at preventing complications that could raise the level of serum calcium. Efforts should be made to prevent volume contraction and prolonged bed rest.
Does calcitonin help with bone resorption?
Combining calcitonin with plicamycin or a bisphosphonate can enhance the rate of decline of the serum calcium level. Bone resorption also can be reduced by getting patients out of bed to stand or walk.
What is the treatment for severe hypercalcaemia?
Severe hypercalcaemia requires admission to hospital and treatment with aggressive intravenous hydration and bisphosphonates along with treatment of the underlying disease. Hypercalcaemia is a common finding in the setting of primary care, 1 as well as in emergency departments 2 and patients admitted to hospital.
What causes mild hypercalcaemia?
Mild hypercalcaemia is usually caused by primary hyperparathyroidism, the treatment for which is typically surgery; those aged 50 or more with serum calcium levels <0.25 mmol/L above the upper limit of normal and without end organ damage may be followed up conservatively.
What causes hypercalcaemia in the body?
Parathyroid related causes of hypercalcaemia comprise primary (including the various genetic forms) and tertiary hyperparathyroidism. Parathyroid hormone is the main regulator of calcium homeostasis and its primary increased secretion alters the regulation of serum calcium by acting on different target organs (bone, kidney, gut).
What is high calcitriol?
High serum calcitriol levels are typically associated with lymphoproliferative and granulomatous disorders (table). In this context, diagnoses should be considered even in the setting of normal serum calcitriol levels when parathyroid hormone and parathyroid hormone related protein levels are suppressed.
What is the effect of malignant cells on the absorption of calcium?
Malignant cells and granulomas can over-express 1-α-hydroxylase and increase the conversion of calcidiol to the active form of vitamin D, calcitriol, leading to increased intestinal absorption of calcium , hypercalciuria, and hypercalcaemia.
Is hypercalcaemia a prognostic factor?
If the primary malignancy is unknown, the need for a rapid differential diagnosis is critical, as hypercalcaemia represents a negative prognostic factor in people with cancer.
Can hypercalcaemia be managed in outpatient?
People presenting with a history of mild asymptomatic hypercalcaemia typically have a diagnosis of primary hyperpara thyroidism and could be managed in the outpatient setting. People with severe, new onset hypercalcaemia with symptoms require admission to hospital for intravenous treatment and diagnosis.
