110 mcg (2 sprays) per nostril once daily; maximum: 440 mcg (4 sprays) per nostril once daily. Intranasal administration.
1-2 inhalations (50-100 mcg) per nostril twice daily (100-200 mcg/day total).
Terminal elimination half-life is approximately 3-4 hours after intranasal administration; however, due to prolonged residence time in nasal mucosa, clinical effects persist beyond plasma half-life.
Terminal elimination half-life is approximately 3.5 hours after intranasal administration. Clinically, this short half-life supports twice-daily dosing for sustained effect.
Primarily hepatic via CYP3A4; main metabolites are 6β-hydroxytriamcinolone acetonide and 21-carboxylic acid derivative.
Hepatic via cytochrome P450 3A4 (CYP3A4) to active metabolite beclomethasone-17-monopropionate, which is further metabolized.
Primarily hepatic metabolism via CYP3A4; renal excretion accounts for <5% of unchanged drug; biliary/fecal excretion of metabolites accounts for ~60% of total clearance.
Primarily hepatic metabolism; excreted in urine (approximately 10% as unchanged drug and metabolites) and feces (approximately 80% as metabolites).
Approximately 99% bound to serum proteins, primarily albumin and alpha-1-acid glycoprotein.
Approximately 87% bound to plasma proteins, primarily albumin.
Vd is approximately 2-3 L/kg, indicating extensive tissue distribution; clinical significance: large Vd suggests sequestration in tissues, potentially prolonging retention.
Volume of distribution is approximately 2.6 L/kg, indicating extensive tissue distribution.
Intranasal: Absolute bioavailability is approximately 3-5% due to extensive first-pass metabolism and limited absorption from nasal mucosa.
Intranasal: approximately 50% systemic bioavailability due to direct absorption across nasal mucosa and some gastrointestinal absorption from swallowed portion. Oral: low and variable (approximately 20%) due to first-pass metabolism.

No significant food interactions known. However, grapefruit juice may slightly increase systemic exposure; avoid excessive consumption.
No significant food interactions. Grapefruit and grapefruit juice do not interact with intranasal beclomethasone. Avoid alcohol if it exacerbates nasal congestion.
FDA Pregnancy Category C. In animal studies, corticosteroids have been shown to be teratogenic at relatively low doses. There are no adequate and well-controlled studies in pregnant women. Nasacort should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. First trimester: Risk cannot be ruled out; avoid unless clearly needed. Second and third trimesters: Limited data; use with caution. Potential fetal risks include orofacial clefts (conflicting data), intrauterine growth restriction, and adrenal suppression in neonates with prolonged maternal use of high doses.
VANCENASE (beclomethasone dipropionate) is an inhaled corticosteroid. In animal studies, corticosteroids have been shown to be teratogenic. However, inhaled corticosteroids at recommended doses are not associated with a significant increase in congenital malformations. First trimester: Limited data, but no clear evidence of increased risk. Second and third trimesters: Risk of intrauterine growth restriction (IUGR) with prolonged high-dose systemic exposure; inhaled doses minimize systemic absorption.
It is not known whether triamcinolone acetonide is excreted in human breast milk. Because other corticosteroids are excreted in human milk, caution should be exercised when Nasacort is administered to a nursing woman. The M/P ratio is unknown. Low doses via intranasal route are unlikely to produce significant systemic levels; however, consider risk-benefit.
Beclomethasone is excreted in breast milk in small amounts. Inhaled corticosteroids at therapeutic doses are considered compatible with breastfeeding. The milk-to-plasma ratio is not well established for beclomethasone; assume low due to extensive first-pass metabolism. Risks to infant are negligible at maternal inhaled doses.
No specific dosing adjustments are recommended for pregnancy based on pharmacokinetic changes. Use the lowest effective dose. Increased plasma volume and altered metabolism during pregnancy may decrease systemic exposure, but intranasal application minimizes systemic absorption. No dose adjustment is typically required, but clinical monitoring for efficacy is advised.
No routine dose adjustment required for beclomethasone dipropionate during pregnancy. Pharmacokinetic changes (increased clearance, decreased plasma protein binding) may theoretically reduce systemic exposure, but inhaled doses are titrated to clinical response. Use lowest effective dose to maintain asthma control.
For optimal efficacy, prime the nasal spray by actuating 5 times or until a fine mist appears. If not used for 7+ days, re-prime with 2 actuations. Instruct patient to blow nose gently before use and tilt head slightly forward. Avoid spraying directly onto nasal septum to reduce risk of epistaxis. May cause growth suppression in children; monitor height regularly if long-term use. Onset of action is within 12-24 hours, but maximal effect may take 2-3 weeks.
VANCENASE (beclomethasone dipropionate) is an intranasal corticosteroid. Onset of action is not immediate; regular use for several days to weeks is needed for full effect. Priming with 6-7 sprays after prolonged non-use is required. Shake well before use. Avoid spraying directly onto the nasal septum to prevent irritation and bleeding. May cause epistaxis and nasal septal perforation with long-term use. Monitor for signs of adrenal suppression when used at higher than recommended doses.
