Not approved for use in pediatric patients.
Apply a thin layer of 1% cream twice daily for children aged 2 years and older; not indicated for children under 2 years.
No specific dose adjustment; monitor for increased sensitivity and renal function.
No specific dose adjustment recommended; apply a thin layer of 1% cream twice daily as for adults.
This drug should be used primarily for treatment of progressive, potentially life-threatening fungal infections; it is not intended for non-invasive forms of disease (e.g., oral thrush, vaginal candidiasis).
Long-term safety of topical calcineurin inhibitors has not been established; rare cases of malignancy (e.g., lymphoma, skin cancer) have been reported; use should be limited to short-term and intermittent treatment.
Monitor renal function closely; may cause dose-dependent nephrotoxicity. Premedicate for infusion reactions (fever, chills, rigors). Monitor electrolytes (hypokalemia, hypomagnesemia). Risk of cardiotoxicity with rapid infusion. Use caution in patients with renal impairment; dose adjustment required.
Increased risk of infections (e.g., eczema herpeticum, varicella zoster); avoid use on malignant or premalignant skin conditions; lymphadenopathy; photosensitivity; not recommended in patients with Netherton syndrome; potential for systemic immunosuppression; monitor for local irritation.
Hypersensitivity to amphotericin B or any component of the formulation, unless the benefit outweighs the risk.
Hypersensitivity to pimecrolimus or any component of the formulation; history of malignancy; application to areas of active infection; Netherton syndrome; immunocompromised patients.
Avoid grapefruit and grapefruit juice as they may increase fingolimod concentrations. No specific dietary restrictions, but maintain adequate hydration.
No known food interactions. Avoid grapefruit juice as it may increase drug levels (CYP3A4 inhibition).
Category D. First trimester: increased risk of cardiac malformations (Ebstein anomaly) and neural tube defects. Second/third trimesters: fetal toxicity including oligohydramnios, premature closure of ductus arteriosus, and neonatal renal impairment.
FDA Pregnancy Category C. Systemic exposure is minimal after topical application, but animal studies have shown developmental toxicity. No adequate human studies; risk cannot be excluded. Avoid in pregnancy unless clearly needed.
Contraindicated. Excreted in human milk; M/P ratio not determined. Potential for serious adverse reactions in breastfed infants.
Not recommended. Pimecrolimus is excreted in milk in animal studies; unknown in humans. M/P ratio not available. Potential for serious adverse reactions in nursing infants.
Increased renal clearance in pregnancy may require dose increments of 30-50% to maintain therapeutic levels; monitor serum lithium concentrations and adjust dose to therapeutic range (0.6-1.2 m Eq/L).
No dose adjustment necessary; use minimal amount to control symptoms. Systemic absorption is negligible, so pharmacokinetic changes in pregnancy do not alter dosing.
ABLYSINOL (fingolimod) is a sphingosine-1-phosphate receptor modulator used for relapsing forms of multiple sclerosis. First-dose monitoring for bradycardia (6 hours) is mandatory; consider pre-treatment ECG. Avoid live vaccines during and for 2 months after therapy. Monitor for macular edema (ophthalmologic exam at baseline and 3-4 months). Lymphopenia is expected; check CBC before initiation and periodically. Drug interactions: QTc-prolonging agents, immunosuppressants, beta-blockers, calcium channel blockers. Do not use in patients with recent MI, unstable angina, stroke, TIA, or certain arrhythmias.
Topical calcineurin inhibitor for atopic dermatitis, reserved as second-line therapy for mild-to-moderate eczema due to boxed warning for rare malignancy risk. Apply thin layer only; avoid occlusive dressings. Do not use in immunocompromised patients. Intermittent use is recommended; continuous long-term use safety not established.
Stay hydrated and avoid grapefruit juice; it may increase drug levels.,Report any vision changes, slow heartbeat, or dizziness immediately.,Avoid pregnancy; use effective contraception during and for 2 months after stopping.,Do not receive live vaccinations during treatment.,Take exactly as prescribed; do not skip doses or stop suddenly.
Apply only to affected skin areas; avoid eyes, mouth, and open wounds.,Use for short durations; do not use continuously for extended periods.,Avoid sun exposure and tanning beds; use sunscreen on treated areas.,Do not cover treated skin with bandages or wraps unless instructed.,Report any signs of infection, skin burning, or new skin growths to your doctor.,This drug is for external use only; wash hands after application unless treating hands.,Do not use if you have a weakened immune system or active skin infection.
