Terminal elimination half-life is 8-12 hours in adults with normal renal function; prolonged to 18-24 hours in moderate renal impairment (Cr Cl 30-50 m L/min).
Dexamethasone is metabolized primarily in the liver via CYP3A4; topical antibiotics (neomycin, polymyxin B) are minimally absorbed and not significantly metabolized.
Hepatic via cytochrome P450 (CYP3A4); active metabolites.
Renal elimination of unchanged drug accounts for 30-40% of the dose; fecal/biliary elimination is 50-60% as metabolites. Less than 10% is excreted unchanged in feces.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; less than 10% metabolized hepatically.

Child-Pugh Class A: no adjustment; Child-Pugh Class B/C: no data available; use with caution
No dose adjustment required for hepatic impairment.
Children 6-11 years: 1 puff (50 mcg) per nostril twice daily; Children ≥12 years: same as adult
Safety and efficacy in pediatric patients have not been established.
No specific dose adjustment; monitor for adrenal suppression and osteoporosis risk with prolonged use
No specific dose adjustment; use with caution due to potential increased skin fragility.
Prolonged use may result in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision, and posterior subcapsular cataract formation. Prolonged use may suppress the host response and thus increase the hazard of secondary ocular infections. In those diseases causing thinning of the cornea or sclera, perforations have been known to occur with the use of topical steroids.
None.
Prolonged use may lead to ocular hypertension/glaucoma,Posterior subcapsular cataract formation,Delayed wound healing,Secondary ocular infections (including fungal infections),Corneal/scleral thinning and perforation,Systemic absorption with prolonged use (especially in children),Avoid use in patients with known hypersensitivity to any component
Orthostatic hypotension and syncope, especially with first dose,May cause dizziness, drowsiness, or lightheadedness,Use caution in patients with hepatic impairment,May exacerbate angina or heart failure
Epithelial herpes simplex keratitis (dendritic keratitis),Vaccinia, varicella, and other viral infections of the cornea and conjunctiva,Mycobacterial infections of the eye,Fungal diseases of ocular structures,Hypersensitivity to any component of the formulation
Hypersensitivity to alpha-blockers,History of orthostatic hypotension,Micturition syncope,Severe renal impairment,Concomitant use with PDE-5 inhibitors (e.g., sildenafil) due to risk of hypotension
No specific food interactions. Avoid grapefruit juice as it may increase systemic exposure to ciclesonide via CYP3A4 inhibition.
No specific food interactions. However, high-fat meals may increase systemic absorption of topical tretinoin marginally; no dietary restrictions necessary. Avoid excessive vitamin A supplements to reduce risk of hypervitaminosis A.
Pregnancy Category C. First trimester: potential for teratogenicity based on animal studies; avoid unless benefit outweighs risk. Second/third trimester: drug may cause fetal harm due to pharmacological effects; use only if clearly needed.
Pregnancy Category C. First trimester: No adequate human studies; animal studies suggest embryocidal and teratogenic effects at high doses. Second/third trimester: Potential for fetal harm; avoid unless benefit outweighs risk.
Excreted in human milk in unknown amounts; M/P ratio not established. Caution advised due to potential for serious adverse reactions in nursing infants; discontinue drug or nursing depending on importance to mother.
Unknown if excreted in human milk; M/P ratio not established. Caution advised due to potential for serious adverse reactions in nursing infants.
No established dose adjustments in pregnancy; pharmacokinetics may be altered due to increased plasma volume and metabolism. Use lowest effective dose; individualize therapy based on clinical response.
Increased plasma volume may reduce drug levels; consider dose adjustment based on therapeutic drug monitoring. No specific dose adjustment established; use lowest effective dose.
AEROSEB-DEX is a fixed-dose combination of an inhaled corticosteroid (ciclesonide) and a long-acting beta-agonist (formoterol). Use as maintenance therapy for asthma, not for acute bronchospasm. Rinse mouth after inhalation to prevent oral candidiasis. Monitor for adrenal suppression with prolonged use. Dose formoterol component at low to moderate doses to minimize risk of asthma-related death.
ALPHADERM (tretinoin 0.05% cream) is a retinoid used for photoaging and acne. Apply a pea-sized amount to dry skin 30 minutes after cleansing; avoid concomitant use of other topical retinoids or exfoliants to prevent irritation. Initiate therapy every other night to build tolerance. Strict sun protection required: use SPF 30+ daily. May cause initial flare of acne (retinoid 'purging') lasting 2-4 weeks. Contraindicated in pregnancy (FDA Category C).
Use regularly as prescribed, not for sudden breathing problems.,Rinse mouth with water after each use to prevent thrush.,Do not stop suddenly; taper under doctor guidance.,Seek emergency if rescue inhaler not effective.,Report worsening asthma, chest pain, or signs of steroid excess.
Apply a thin layer to affected areas once daily at bedtime, 30 minutes after washing and drying face.,Avoid excessive sun exposure; use broad-spectrum sunscreen and protective clothing.,Do not use with other medicated topical products, including benzoyl peroxide or salicylic acid.,Expect mild redness, peeling, or stinging initially; this usually subsides with continued use.,Notify your doctor if you are pregnant, planning pregnancy, or breastfeeding.,Store at room temperature away from heat and light.
