Amlodipine dosing?
The doses for Amlodipine are 2.5mg, 5mg and 10mg.In older adults I start at the lowest dose at 2.5 mg and titrate slowly. If you are younger or middle aged your Doctor might start you on a higher dose such as 5mg.Usually when titrating the dose up, I wait 7-14 days before changing the dose. In my experience for better control of coronary artery disease and chronic stable angina patients end up being titrated to 10mg daily. Of course, the higher the dose the higher the chances of side effects.

It takes Norvasc 6-12 hours to peak in your plasma. That means it takes Norvasc 6-12 hours to reach its highest concentration in your plasma. This medication does not work immediately and can reduce your blood pressure significantly after 24-48 hours.
