Calcipotriene Cream, 0.005%, is indicated for the treatment of plaque psoriasis. The safety and effectiveness of topical calcipotriene in dermatoses other than psoriasis have not been established.

Calcipotriene Cream is contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation. It should not be used by patients with demonstrated hypercalcemia or evidence of vitamin D toxicity. Calcipotriene Cream should not be used on the face.

Contact dermatitis, including allergic contact dermatitis, has been observed with the use of Calcipotriene Cream.

Pregnancy Teratogenic Effects Studies of teratogenicity were done by the oral route where bioavailability is expected to be approximately 40-60% of the administered dose. Increased rabbit maternal and fetal toxicity was noted at 12 μg/kg/day (132 μg/m 2 /day). Rabbits administered 36 μg/kg/day (396 μg/m 2 /day) resulted in fetuses with a significant increase in the incidences of pubic bones, forelimb phalanges, and incomplete bone ossification.

In a rat study, oral doses of 54 μg/kg/day (318 μg/m 2 /day) resulted in a significantly higher incidence of skeletal abnormalities consisting primarily of enlarged fontanelles and extra ribs. The enlarged fontanelles are most likely due to calcipotriene's effect upon calcium metabolism. The maternal and fetal calculated no-effect exposures in the rat (43.2 μg/m 2 /day) and rabbit (17.6 μg/m 2 /day) studies are approximately equal to the expected human systemic exposure level (18.5 μg/m 2 /day) from dermal application.

There are no adequate and well-controlled studies in pregnant women. Therefore, Calcipotriene Cream should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
