Digitalizing dose: 0.01-0.02 mg/kg IV or IM, given in divided doses over 24 hours. Maintenance: 10-20% of digitalizing dose daily. Not recommended for neonates due to prolonged half-life.
10 mg/kg IV every 6 hours; maximum 500 mg per dose.
Reduce dose by 25-50% due to decreased renal function and increased sensitivity. Monitor serum levels and renal function closely.
Consider renal function; start at lower end of dosing range due to age-related decreased renal clearance.
Can cause potentially fatal arrhythmias; use only when clearly indicated and monitor serum levels.
None
Narrow therapeutic index; toxicity risk increased with hypokalemia, hypomagnesemia, hypercalcemia, renal impairment; monitor ECG and drug levels.
Infusion-related reactions (IRRs): premedicate and monitor during infusion; interrupt or discontinue if severe.,Interstitial lung disease (ILD)/pneumonitis: monitor for new or worsening respiratory symptoms; withhold or permanently discontinue.,Dermatologic adverse reactions (rash, dry skin, pruritus): manage with topical corticosteroids, emollients, and oral antihistamines; consider dose modification.,Ocular toxicity: monitor for keratitis, uveitis; refer to ophthalmology if symptoms develop.,Embryo-fetal toxicity: can cause fetal harm; advise effective contraception.
Ventricular fibrillation, digitalis toxicity, hypersensitivity, AV block (unless pacemaker present), Wolff-Parkinson-White syndrome.
None
Avoid licorice, which can cause hypokalemia. Maintain consistent intake of potassium-rich foods (bananas, oranges) to avoid fluctuations. No known significant food interactions beyond electrolyte effects.
Avoid grapefruit and grapefruit juice as they inhibit CYP3A4 metabolism, increasing amiodarone levels and risk of toxicity. Limit alcohol consumption due to potential hepatotoxicity. High-fat meals may increase absorption; take consistently with or without food.
Pregnancy Category C. First trimester: No adequate human studies; animal studies show fetal risk. Second/third trimester: Risk of fetal bradycardia, cardiac glycoside toxicity; avoids if possible.
No human data available; in animal studies, no teratogenicity observed at clinically relevant doses. First trimester: data insufficient to assess risk. Second and third trimesters: no known fetal harm.
Deslanoside is excreted in breast milk; estimated infant dose 0.1-0.5% of maternal weight-adjusted dose; M/P ratio not well defined. Monitor infant for bradycardia, feeding difficulties; benefit likely outweighs risk.
No data on excretion in human milk; M/P ratio unknown. Caution recommended; benefits of breastfeeding should be weighed against potential risk to infant.
Increased renal clearance in pregnancy may require higher doses; monitor serum drug levels and adjust accordingly. Reduced dosing in third trimester may be needed due to volume expansion.
No specific dose adjustments required in pregnancy; pharmacokinetic changes not well-characterized. Use lowest effective dose and monitor clinical response.
Cedilanid-D (deslanoside) is a rapidly acting parenteral digitalis glycoside. Use with extreme caution in renal impairment due to reduced clearance. Monitor serum potassium and magnesium; hypokalemia and hypomagnesemia potentiate toxicity. Administer slow IV push over 5 minutes to avoid arrhythmias. Therapeutic drug monitoring less common due to short half-life of 33 hours. Contraindicated in ventricular tachycardia and AV block (unless due to atrial fibrillation).
AMVAZ (amiodarone) has a long half-life (up to 107 days) and can cause thyroid, pulmonary, hepatic, and skin toxicity. Monitor thyroid function (TSH, T3, T4), liver enzymes (ALT, AST), and perform baseline pulmonary function tests and chest X-ray. Corneal microdeposits are common and may cause visual halos; usually reversible. Administer loading dose to achieve therapeutic effect more quickly. Avoid use with grapefruit juice as it increases drug levels.
Take exactly as prescribed; do not double doses.,Report symptoms of toxicity: nausea, vomiting, visual disturbances (yellow-green halos), irregular heartbeat.,Avoid over-the-counter medications without consulting doctor.,Maintain consistent potassium intake; avoid high-potassium foods or supplements unless advised.,Monitor daily weight and report rapid weight gain or edema.
Take AMVAZ exactly as prescribed; do not stop without consulting your doctor.,Avoid grapefruit and grapefruit juice while taking this medication.,Report any new or worsening shortness of breath, cough, chest pain, or palpitations immediately.,Notify your doctor if you experience vision changes, yellowing of skin/eyes, dark urine, or unusual fatigue.,Use effective contraception during treatment and for at least 6 months after stopping.,Avoid excessive sun exposure; use sunscreen and protective clothing due to risk of skin discoloration and photosensitivity.,Do not take over-the-counter medications or herbal supplements without checking with your doctor.,Regular blood tests and eye exams are necessary while on this medication.
