Amlodipine Dosage Guidelines

Pediatric Considerations

The American Academy of Pediatrics recommends a maximum dose of 5 mg once daily for children aged 6-17 years, with doses exceeding 5 mg daily not recommended due to lack of studies in this population 1
Children under 6 years of age should not receive amlodipine, as recommended by the American Academy of Pediatrics 1

For idiopathic pulmonary arterial hypertension (IPAH) in vasoreactive patients, the European Society of Cardiology suggests doses up to 20 mg daily may be used, though this is an off-label indication 2
The European Society of Cardiology recommends that this higher dosing is reserved only for carefully selected IPAH patients who demonstrate positive acute vasodilator response during right heart catheterization 2
When coadministered with simvastatin or lovastatin, the American Heart Association advises that amlodipine doses should not exceed 20 mg daily due to moderate increases in statin exposure and increased risk of myopathy 3

The long half-life of amlodipine (30-50 hours) supports true once-daily dosing and allows for sustained blood pressure control throughout the 24-hour period, as noted by the American College of Cardiology 4
