Apply once daily to affected areas of skin, not exceeding 100 g/week or 30 m L/day. Do not use under occlusive dressings.
Apply to affected areas once daily; maximum weekly dose should not exceed 100 g (calcipotriene 0.005% and betamethasone dipropionate 0.064% as combination ointment or foam).
Calcipotriene: 12-24 hours; betamethasone dipropionate: 4-6 hours (parent), 3-5 hours (active metabolite betamethasone 17-propionate).
Calcipotriene: not applicable due to minimal systemic exposure. Betamethasone dipropionate: terminal half-life of betamethasone after topical application is approximately 5-6 hours.
Calcipotriene undergoes hepatic metabolism primarily via cytochrome P450 (CYP) enzymes, including CYP24A1. Betamethasone dipropionate is metabolized in the liver via CYP3A4.
Calcipotriene: hepatic metabolism via CYP24A1 and other enzymes; betamethasone dipropionate: mainly hepatic metabolism via CYP3A4 to various inactive metabolites.
Calcipotriene: renal elimination of metabolites; betamethasone dipropionate: primarily renal (70%) and biliary/fecal (30%) as metabolites.
Calcipotriene: negligible systemic absorption; absorbed fraction undergoes hepatic metabolism and is excreted in feces (approx. 70%) and urine (approx. 20%). Betamethasone dipropionate: absorbed dose metabolized in liver, metabolites excreted primarily in urine (60-70%) and feces (20-30%).
Calcipotriene: ~94% bound to plasma proteins; betamethasone dipropionate: ~64% bound (predominantly albumin).
Calcipotriene: >90% bound to plasma proteins (albumin). Betamethasone dipropionate: >90% bound to albumin.
Calcipotriene: >1 L/kg (extensive tissue distribution); betamethasone dipropionate: not well characterized, likely large due to lipophilicity.

No significant food interactions. No dietary restrictions necessary for this topical medication.
No clinically significant food-drug interactions. However, maintain adequate calcium and vitamin D intake as part of a balanced diet, but avoid excessive calcium supplementation due to potential hypercalcemia risk with extensive use.
Topical calcipotriene/betamethasone dipropionate has low systemic absorption; however, betamethasone is a corticosteroid. Animal studies with high-dose topical corticosteroids show increased risk of cleft palate and fetal growth restriction. In humans, first-trimester use of potent corticosteroids is associated with a small increased risk of oral clefts (OR 1.5). Second/third trimester: Prolonged use may cause fetal adrenal suppression and low birth weight. Avoid application to large areas (>30% BSA) or under occlusion.
FDA Pregnancy Category C. Calcipotriene: No adequate human studies; animal studies show no teratogenicity at topical doses. Bethamethasone dipropionate: Corticosteroids can cause cleft palate, intrauterine growth restriction, and adrenal suppression in animal studies; human risk with topical use is low due to minimal systemic absorption. Avoid large areas or prolonged use in pregnancy. First trimester: theoretical risk but limited data. Second/third trimesters: low risk if used sparingly.
Minimal systemic absorption after topical use. No specific M/P ratio available. Exercise caution: avoid application to breast area to prevent infant ingestion. Monitor infant for signs of adrenal suppression (rare). Use lowest effective dose for shortest duration.
Not known if excreted in human milk. Calcipotriene is likely excreted due to low molecular weight; betamethasone may appear in milk. M/P ratio not available. Use caution; apply smallest amount to smallest area, avoid breast area. Consider benefits vs risks.
No dose adjustment needed for topical use. However, restrict application to <30% body surface area and avoid prolonged treatment; use shortest possible duration. Systemic absorption may increase with psoriatic skin barrier disruption; monitor for corticosteroid side effects.
No formal dose adjustment guidelines. Use minimum effective dose for shortest duration. Avoid occlusion, extensive areas, or prolonged treatment. Monitor for local and systemic adverse effects.
Apply only to psoriatic plaques, not to normal skin or flexures. Maximum weekly dose: 100g. Avoid occlusion. Use with caution on face, genitals, and intertriginous areas due to risk of corticosteroid atrophy. Discontinue if hypersensitivity develops. Monitor for hypercalcemia if used on extensive areas. Not recommended for use in children under 18 years.
Avoid use on face, groin, axillae, or in intertriginous areas due to increased risk of corticosteroid side effects. Apply only to affected plaques; limit total weekly dose to ≤100 g or 60 m L to minimize risk of HPA axis suppression. Discontinue if skin atrophy, telangiectasias, or striae develop. Monitor for hypercalcemia in patients with extensive plaque psoriasis due to calcipotriene absorption. For patients with moderate-to-severe plaque psoriasis, consider sequential or rotational therapy to minimize long-term corticosteroid exposure.

"Coadministration of Betamethasone, a potent corticosteroid, may reduce the therapeutic efficacy of Miglustat, a glucosylceramide synthase inhibitor used for Gaucher disease and Niemann-Pick type C. Betamethasone can induce hepatic CYP3A4 isoenzymes, potentially increasing the metabolism of Miglustat, though Miglustat is primarily renally excreted and not extensively metabolized. The interaction may also involve corticosteroid-mediated alterations in drug transport or GlcCer synthesis pathways, leading to decreased Miglustat plasma concentrations and diminished clinical response, including worsening of neurological symptoms in Niemann-Pick disease."
"Concomitant use of betamethasone, a corticosteroid, with donepezil, a cholinesterase inhibitor used in Alzheimer's disease, may increase the risk of gastrointestinal adverse effects including gastric ulceration and hemorrhage. Corticosteroids inhibit prostaglandin synthesis and mucosal protection, while donepezil enhances cholinergic tone, increasing gastric acid secretion. This additive effect on the gastric mucosa can lead to clinically significant ulcer formation or gastrointestinal bleeding, particularly in elderly patients."
"Betamethasone, a potent corticosteroid, can induce hyperglycemia and dyslipidemia, potentially counteracting the lipid-lowering effects of atorvastatin. Concurrent use may increase the risk of corticosteroid-related adverse effects such as fluid retention, hyperglycemia, and myopathy. Atorvastatin may also increase systemic exposure to corticosteroids via inhibition of CYP3A4, though this interaction is generally not clinically significant."
