Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

calcium carbonate Food/Lifestyle

Applies to: Os-Cal Extra D3 (calcium / vitamin d)

Calcium absorption may be increased by taking it with food. However, foods high in oxalic acid (spinach or rhubarb), or phytic acid (bran and whole grains) may decrease calcium absorption. Calcium may be taken with food to increase absorption. Consider spacing calcium administration for at least 2 hours before or after consuming foods high in oxalic acid or phytic acid. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate:

ergocalciferol Food/Lifestyle

Applies to: Os-Cal Extra D3 (calcium / vitamin d)

Treatment with ergocalciferol may require you to adjust your dietary intake of foods which contain natural or added calcium, phosphate (organic and inorganic), and vitamin D or grapefruit. Ingesting too much vitamin D or having elevated calcium and/or phosphorus levels in the blood and urine can lead to toxic effects, such as having an irregular heart rhythm, seizures, kidney stones, and eventual calcification of your blood vessels, cornea and/or the soft tissues in your body. Consumption of grapefruit and grapefruit juice may also alter the blood levels and effects of ergocalciferol. Your doctor will monitor the levels of calcium and phosphorus in your blood during treatment with ergocalciferol. Please speak with your healthcare team to determine if you require a specialized diet, particularly if you have reduced kidney function, and to discuss any other questions or concerns you have. You may require additional monitoring or a dose adjustment of ergocalciferol if your diet changes. Fortified foods will state on their labeling how much calcium, phosphate, and/or vitamin D has been added. The National Institutes of Health, Office of Dietary Supplements also provides information on which foods contain calcium, phosphorus, and vitamin D. You should avoid abrupt changes in your dietary calcium intake and seek medical attention if you experience early symptoms of vitamin D intoxication such as weakness, fatigue, headache, drowsiness, vertigo, ringing in the ears, loss of appetite, nausea, vomiting, constipation, dry mouth, metallic taste, muscle pain, bone pain, muscle incoordination, and low muscle tone. Late symptoms may include frequent urination, excessive thirst, weight loss, conjunctivitis ("pink eye"), light sensitivity, runny nose, itching, increased body temperature, and irregular heart rhythm. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate:

losartan Food/Lifestyle

Applies to: losartan

If you are taking losartan you should avoid potassium-containing salt substitutes or over-the-counter potassium supplements without first talking to your doctor. This can cause high levels of potassium in your blood. High levels of potassium can cause weakness, irregular heartbeat, confusion, tingling of the extremities, or feelings of heaviness in the legs. Call your doctor at once if you have any of these symptoms.

In some patients grapefruits and grapefruit juice may decrease the efficacy of losartan. Grapefruits and grapefruit juice should be avoided if an interaction is suspected. Orange juice is not expected to interact.

Disease interactions

25 potential interactions Applies to: 17 conditions, including Heart Failure, Arrhythmia, Diabetes Mellitus, Tachyarrhythmia, and Sarcoidosis.

Achlorhydria

Major:

Os-Cal Extra D3

The calcium carbonate in Os-Cal Extra D3 has a major potential interaction with Achlorhydria.

Calcium is absorbed from the intestinal tract by active transport and passive diffusion. Malabsorption syndromes (celiac disease, GI resection), deficiency of vitamin D, parathyroid hormone, or calcitonin, or an alkaline gastric pH (achlorhydria, carbonate or phosphate salts) can decrease the absorption of oral formulations of calcium. Calcium is available in oral and parenteral formulations.

Angioedema

Major:

losartan

Losartan has a major potential interaction with Angioedema.

The use of these agents is contraindicated in patients with a history of angioedema related to previous angiotensin-converting enzyme (ACE) inhibitor or angiotensin II receptor blocker (ARB) therapy or in patients with hereditary angioedema. Patients with a history of angioedema unrelated to these agents may be at increased risk of angioedema while receiving angiotensin II receptor (AR) antagonists. Patients should be advised to immediately report any signs or symptoms suggestive of angioedema (swelling of face, extremities, eyes, lips, or tongue, or difficulty swallowing or breathing) and to stop taking the medication until otherwise directed by their physician. Emergency therapy and/or measures to prevent airway obstruction are required for angioedema involving the tongue, glottis, or larynx. Treatment with angiotensin II receptor (AR) antagonists should be discontinued permanently if angioedema develops in association with therapy.

Arrhythmia

Major:

Os-Cal Extra D3

The calcium carbonate in Os-Cal Extra D3 has a major potential interaction with Arrhythmia.

Calcium is involved in cardiac muscle contraction and electrical impulse conduction. Therapy with calcium salt formulations (particularly IV) should be administered cautiously to patients with cardiac disease. Patients receiving cardiac glycosides and concomitant IV calcium may experience arrhythmias. Therapy with IV calcium should be administered slowly and at reduced dosages in patients with cardiac disease.

Moderate:

Os-Cal Extra D3

The ergocalciferol in Os-Cal Extra D3 has a moderate potential interaction with Arrhythmia.

Vitamin D analogs function to increase serum calcium concentrations and can exacerbate arrhythmias, particularly in patients receiving cardiac glycosides. Therapy with vitamin D analogs should be administered cautiously in patients with or predisposed to cardiac arrhythmias. Clinical monitoring of serum electrolyte concentrations and cardiac function is recommended.

Biliary Obstruction

Moderate:

losartan

Losartan has a moderate potential interaction with Biliary Obstruction.

Losartan is converted in the liver to an active carboxylic acid metabolite and several inactive metabolites, and both parent drug and metabolites are eliminated by the kidney (35%) as well as by biliary excretion (60%). Dosage adjustments are not necessary in patients with renal impairment unless they are also volume-depleted, in which case therapy should be initiated under medical supervision. In patients with cirrhosis, however, significantly increased plasma concentrations of parent drug and active metabolite have been reported. Therapy with losartan should be initiated cautiously at a reduced dosage (50%) in patients with impaired liver function.

Moderate:

Os-Cal Extra D3

The ergocalciferol in Os-Cal Extra D3 has a moderate potential interaction with Biliary Obstruction.

Vitamin D analogs are fat soluble and oral formulations require bile for adequate intestinal absorption. Hepatic and/or biliary dysfunction decrease the absorption of vitamin D analogs. Metabolites of vitamin D analogs are primarily excreted in bile and feces. Ergocalciferol, cholecalciferol, and dihydrotachysterol undergo hepatic hydroxylation during metabolic activation. Hepatic impairment can alter the metabolic and therapeutic activity of certain vitamin D analogs. Alternative vitamin D analogs such as calcitriol (active form) may be considered in patients with compromised hepatic function.

Dehydration

Major:

losartan

Losartan has a major potential interaction with Dehydration.

Angiotensin II receptor (AR) antagonists can cause symptomatic hypotension in patients with an activated renin-angiotensin system, such as volume- and/or sodium-depleted patients. Therapy with AR antagonists should be administered cautiously in such patients and in those predisposed to hypovolemic or hyponatremic states (e.g., patients on diuretic therapy, especially if high doses were used or if recently instituted; those on dietary salt restriction; renal dialysis patients). Volume and/or sodium depletion should be corrected prior to initiating therapy with AR antagonists, and the patient should be hemodynamically stable. Ideally, patients at risk for excessive hypotension should initiate AR antagonist therapy under close medical supervision, preferably with a lower dose, and followed closely for the first 2 weeks of treatment and whenever the dosage of AR antagonist or diuretic is increased.

Diabetes Mellitus

Major:

losartan

Losartan has a major potential interaction with Diabetes Mellitus.

The coadministration of some angiotensin II receptor blocker agents with aliskiren is contraindicated in patients with diabetes.

Heart Failure

Moderate:

losartan

Losartan has a moderate potential interaction with Heart Failure.

Angiotensin II receptor (AR) antagonists can cause renal impairment in patients whose renal function depends on the activity of the renin-angiotensin-aldosterone system. In addition, symptomatic hypotension can occur in susceptible individuals, which may compromise renal and myocardial perfusion. In patients with severe congestive heart failure (CHF), treatment with AR antagonists has been associated with oliguria and/or progressive azotemia and, rarely, renal failure, myocardial ischemia, and death. Therapy with AR antagonists should be initiated cautiously in patients with severe CHF, especially when accompanied by volume and/or sodium depletion. In patients who experience a decline in renal function, discontinuation of AR antagonist therapy is usually not required provided there is symptomatic improvement of the heart failure and renal deterioration is well-tolerated. Transient hypotension is also not a contraindication to further treatment with AR antagonists, since therapy can usually be reinstated without difficulty after blood pressure stabilizes.

Hemodialysis

Major:

losartan

Losartan has a major potential interaction with Hemodialysis.

Angiotensin II receptor (AR) antagonists can cause symptomatic hypotension in patients with an activated renin-angiotensin system, such as volume- and/or sodium-depleted patients. Therapy with AR antagonists should be administered cautiously in such patients and in those predisposed to hypovolemic or hyponatremic states (e.g., patients on diuretic therapy, especially if high doses were used or if recently instituted; those on dietary salt restriction; renal dialysis patients). Volume and/or sodium depletion should be corrected prior to initiating therapy with AR antagonists, and the patient should be hemodynamically stable. Ideally, patients at risk for excessive hypotension should initiate AR antagonist therapy under close medical supervision, preferably with a lower dose, and followed closely for the first 2 weeks of treatment and whenever the dosage of AR antagonist or diuretic is increased.

Hypercalcemia

Major:

Os-Cal Extra D3

The ergocalciferol in Os-Cal Extra D3 has a major potential interaction with Hypercalcemia.

Vitamin D analogs such as calciferol and ergocalciferol should not be given to patients with hypercalcemia, malabsorption syndrome, or evidence of vitamin D toxicity.

Hyperkalemia

Moderate:

losartan

Losartan has a moderate potential interaction with Hyperkalemia.

Drugs that inhibit the renin-angiotensin, such as angiotensin II receptor antagonist system can cause hyperkalemia. Concomitant use of these agents with drugs that increase potassium levels may increase the risk of hyperkalemia. Use caution when using these agents together and monitor serum potassium periodically.

Hyponatremia

Major:

losartan

Losartan has a major potential interaction with Hyponatremia.

Angiotensin II receptor (AR) antagonists can cause symptomatic hypotension in patients with an activated renin-angiotensin system, such as volume- and/or sodium-depleted patients. Therapy with AR antagonists should be administered cautiously in such patients and in those predisposed to hypovolemic or hyponatremic states (e.g., patients on diuretic therapy, especially if high doses were used or if recently instituted; those on dietary salt restriction; renal dialysis patients). Volume and/or sodium depletion should be corrected prior to initiating therapy with AR antagonists, and the patient should be hemodynamically stable. Ideally, patients at risk for excessive hypotension should initiate AR antagonist therapy under close medical supervision, preferably with a lower dose, and followed closely for the first 2 weeks of treatment and whenever the dosage of AR antagonist or diuretic is increased.

Liver Disease

Moderate:

losartan

Losartan has a moderate potential interaction with Liver Disease.

Losartan is converted in the liver to an active carboxylic acid metabolite and several inactive metabolites, and both parent drug and metabolites are eliminated by the kidney (35%) as well as by biliary excretion (60%). Dosage adjustments are not necessary in patients with renal impairment unless they are also volume-depleted, in which case therapy should be initiated under medical supervision. In patients with cirrhosis, however, significantly increased plasma concentrations of parent drug and active metabolite have been reported. Therapy with losartan should be initiated cautiously at a reduced dosage (50%) in patients with impaired liver function.

Moderate:

Os-Cal Extra D3

The ergocalciferol in Os-Cal Extra D3 has a moderate potential interaction with Liver Disease.

Vitamin D analogs are fat soluble and oral formulations require bile for adequate intestinal absorption. Hepatic and/or biliary dysfunction decrease the absorption of vitamin D analogs. Metabolites of vitamin D analogs are primarily excreted in bile and feces. Ergocalciferol, cholecalciferol, and dihydrotachysterol undergo hepatic hydroxylation during metabolic activation. Hepatic impairment can alter the metabolic and therapeutic activity of certain vitamin D analogs. Alternative vitamin D analogs such as calcitriol (active form) may be considered in patients with compromised hepatic function.

Malabsorption Syndrome

Major:

Os-Cal Extra D3

The calcium carbonate in Os-Cal Extra D3 has a major potential interaction with Malabsorption Syndrome.

Calcium is absorbed from the intestinal tract by active transport and passive diffusion. Malabsorption syndromes (celiac disease, GI resection), deficiency of vitamin D, parathyroid hormone, or calcitonin, or an alkaline gastric pH (achlorhydria, carbonate or phosphate salts) can decrease the absorption of oral formulations of calcium. Calcium is available in oral and parenteral formulations.

Major:

Os-Cal Extra D3

The ergocalciferol in Os-Cal Extra D3 has a major potential interaction with Malabsorption Syndrome.

Vitamin D analogs such as calciferol and ergocalciferol should not be given to patients with hypercalcemia, malabsorption syndrome, or evidence of vitamin D toxicity.

Phosphate Imbalance

Major:

Os-Cal Extra D3

The calcium carbonate in Os-Cal Extra D3 has a major potential interaction with Phosphate Imbalance.

Elevated serum concentrations of calcium and phosphate can exceed the solubility level and result in calcium- phosphate precipitates that deposit in vascular and renal systems as well as other soft tissues of the body. Therapy with calcium should be administered with extreme caution in patients with hyperphosphatemia (hypoparathyroidism or severe renal impairment). Administration of oral calcium acetate or calcium carbonate, in addition to providing calcium, complexes phosphates within the GI tract. These complexes are eliminated in the feces. Clinical monitoring of serum calcium and phosphate concentrations is necessary.

Moderate:

Os-Cal Extra D3

The ergocalciferol in Os-Cal Extra D3 has a moderate potential interaction with Phosphate Imbalance.

Vitamin D analogs administered in the presence of hyperphosphatemia can result in precipitation of calcium-phosphate deposits within the vascular or renal systems or other soft tissue calcifications. A solubility product (Serum Calcium X Phosphate) should not exceed 70. Serum electrolyte concentrations should be corrected prior to vitamin D analog therapy and monitored during therapy.

Renal Dysfunction

Major:

Os-Cal Extra D3

The calcium carbonate in Os-Cal Extra D3 has a major potential interaction with Renal Dysfunction.

Absorption of oral calcium formulations may be altered and elimination of calcium by the kidney decreased with renal impairment. Hyperphosphatemia occurs during renal failure. Calcium acetate or calcium carbonate, in addition to providing calcium, complexes phosphates within the GI tract. Calcium carbonate can partially correct metabolic acidosis associated with chronic renal failure. Clinical monitoring of renal function and serum calcium and phosphate concentrations is necessary.

Moderate:

losartan

Losartan has a moderate potential interaction with Renal Dysfunction.

Losartan is converted in the liver to an active carboxylic acid metabolite and several inactive metabolites, and both parent drug and metabolites are eliminated by the kidney (35%) as well as by biliary excretion (60%). Dosage adjustments are not necessary in patients with renal impairment unless they are also volume-depleted, in which case therapy should be initiated under medical supervision. In patients with cirrhosis, however, significantly increased plasma concentrations of parent drug and active metabolite have been reported. Therapy with losartan should be initiated cautiously at a reduced dosage (50%) in patients with impaired liver function.

Moderate:

losartan

Losartan has a moderate potential interaction with Renal Dysfunction.

Changes in renal function including acute renal failure can be caused by drugs that inhibit the renin-angiotensin system and by diuretics. Patients whose renal function may depend in part on the activity of the renin-angiotensin system (e.g., patients with renal artery stenosis, chronic kidney disease, severe congestive heart failure, or volume depletion) may be at particular risk of developing acute renal failure with these agents. Monitor renal function periodically in these patients. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in renal function with these agents.

Moderate:

Os-Cal Extra D3

The ergocalciferol in Os-Cal Extra D3 has a moderate potential interaction with Renal Dysfunction.

Ergocalciferol and cholecalciferol undergo renal biotransformation during metabolic activation. Renal impairment can alter metabolic and therapeutic activity of certain vitamin D analogs. Alternative vitamin D analogs such as dihydrotachysterol (hepatic activation) and calcitriol (active form) may be considered in patients with compromised renal function.

Sarcoidosis

Major:

Os-Cal Extra D3

The calcium carbonate in Os-Cal Extra D3 has a major potential interaction with Sarcoidosis.

Hypercalciuria, with or without hypercalcemia, may occasionally occur in patients with sarcoidosis. Elevated calcium levels may result from increased intestinal absorption of calcium, which is related to the extrarenal production of vitamin D by mononuclear phagocytes present within the sarcoid granuloma. Therapy with calcium salts should be administered cautiously and only if necessary in patients with sarcoidosis.

Tachyarrhythmia

Major:

Os-Cal Extra D3

The ergocalciferol in Os-Cal Extra D3 has a major potential interaction with Tachyarrhythmia.

The amine ergot alkaloids, ergonovine and methylergonovine, can cause serious cardiovascular complications because of their vasospastic effects. Hypertension (more often with ergonovine) has been most commonly reported, particularly when administered IV undiluted or at an excessive rate or when used in conjunction with regional anesthesia or vasoconstrictors. Headaches, seizures, cerebrovascular accidents and death have been associated with the hypertensive episodes. Other, less common adverse effects include acute myocardial infarction, transient chest pains, thrombophlebitis, tachycardia and palpitations. Therapy with ergot alkaloids should generally be avoided, except under special circumstances, in patients with chronic hypertension, preeclampsia or eclampsia, cardiovascular disease, cerebrovascular disease, or peripheral vascular disease. Caution is advised when these agents are administered to patients with venoatrial shunts, mitral valve stenosis, or sepsis. Close monitoring of cardiovascular status is highly recommended during therapy.
