Calcipotriene topical Disease Interactions

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.
