Drug interactions
Moderate drug interactions
Moderate:
dihydrotachysterol calcipotriene topical
Applies to: dihydrotachysterol and calcipotriene / dimethicone topical
The medication in calcipotriene topical is absorbed through the skin into the bloodstream and may cause interactions with other medications. Using calcipotriene topical together with dihydrotachysterol may occasionally cause your blood calcium levels to become too high. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if you experience signs and symptoms that may suggest excessive blood calcium levels such as dizziness, weakness, lethargy, muscle pain, headache, loss of appetite, nausea, vomiting, and seizures. 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.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
dihydrotachysterol Food/Lifestyle
Applies to: dihydrotachysterol
Treatment with dihydrotachysterol 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 dihydrotachysterol. Your doctor will monitor the levels of calcium and phosphorus in your blood during treatment with dihydrotachysterol. 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 dihydrotachysterol 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.
Disease interactions
7 potential interactions Applies to: 7 conditions, including Arrhythmia, Liver Disease, Hypercalcemia, Renal Dysfunction, and Biliary Obstruction.
Arrhythmia
Moderate:
dihydrotachysterol
Dihydrotachysterol 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:
dihydrotachysterol
Dihydrotachysterol 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.
Hypercalcemia
Major:
calcipotriene / dimethicone topical
The calcipotriene topical in calcipotriene / dimethicone topical has a major potential interaction with Hypercalcemia.
The use of calcipotriene topical preparations is contraindicated in patients with demonstrated hypercalcemia or evidence of vitamin D toxicity. Calcipotriene is a synthetic vitamin D3 analog. Systemic absorption of topically applied calcipotriene ranges from less than 1% for the scalp solution to 5% to 6% for the ointment. Calcipotriene has been reported to be 100 to 200 times less potent in its effects on calcium utilization than natural vitamin D, which facilitates the absorption of calcium in the intestine. Transient, rapidly reversible elevation of serum calcium has been reported following the topical administration of calcipotriene. If elevation in serum calcium outside the normal range occurs, treatment should be discontinued until normal calcium levels are restored. Patients should be advised to contact their physician if they experience early symptoms of hypercalcemia such as weakness, fatigue, somnolence, headache, anorexia, dry mouth, metallic taste, nausea, vomiting, abdominal cramps, constipation, diarrhea, vertigo, tinnitus, ataxia, exanthema, muscle pain, bone pain, and irritability.
Liver Disease
Moderate:
dihydrotachysterol
Dihydrotachysterol 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.
Phosphate Imbalance
Moderate:
dihydrotachysterol
Dihydrotachysterol 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.
Poisoning by Vitamins
Major:
calcipotriene / dimethicone topical
The calcipotriene topical in calcipotriene / dimethicone topical has a major potential interaction with Poisoning by Vitamins.
The use of calcipotriene topical preparations is contraindicated in patients with demonstrated hypercalcemia or evidence of vitamin D toxicity. Calcipotriene is a synthetic vitamin D3 analog. Systemic absorption of topically applied calcipotriene ranges from less than 1% for the scalp solution to 5% to 6% for the ointment. Calcipotriene has been reported to be 100 to 200 times less potent in its effects on calcium utilization than natural vitamin D, which facilitates the absorption of calcium in the intestine. Transient, rapidly reversible elevation of serum calcium has been reported following the topical administration of calcipotriene. If elevation in serum calcium outside the normal range occurs, treatment should be discontinued until normal calcium levels are restored. Patients should be advised to contact their physician if they experience early symptoms of hypercalcemia such as weakness, fatigue, somnolence, headache, anorexia, dry mouth, metallic taste, nausea, vomiting, abdominal cramps, constipation, diarrhea, vertigo, tinnitus, ataxia, exanthema, muscle pain, bone pain, and irritability.
Renal Dysfunction
Moderate:
dihydrotachysterol
Dihydrotachysterol 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.
