2.1 Adults. The usual initial antihypertensive oral dose of NORVASC is 5 mg once daily, and the maximum dose is 10 mg once daily. Small, fragile, or elderly patients, or patients with hepatic insufficiency may be started on 2.5 mg once daily and this dose may be used when adding NORVASC to other antihypertensive therapy. Medscape - Hypertension-specific dosing for Norvasc (amlodipine), frequency-based adverse effects, comprehensive interactions, contraindications, pregnancy & lactation schedules, and cost information. Norvasc dosing will vary from patient to patient, depending on your age, what you are treating, other existing medical conditions, and other medicines you may already be taking. Norvasc (amlodipine) is a calcium channel blocker that dilates (widens) blood vessels and improves blood flow. Norvasc is used to treat chest pain and other conditions caused by coronary artery disease. Norvasc comes in three tablet sizes, which should be taken once a day, with or without food: 2.5 mg, 5 mg, and 10 mg. Adults typically start out with a 5 mg dose, with a maximum dose of 10 mg. It is rare, but when you first start taking NORVASC or increase your dose, you may have a heart attack or your angina may get worse. If that happens, call your doctor right away or go directly to a hospital emergency room. Adults.

I have a low heart rate but have developed high blood pressure. I take Altace and Norvasc at almost maximum dose to keep it under control. The Altace doesn't do much, but supposedly is a good drug for people with CAD. I will very often add a calcium channel blocker like norvasc second and maximize that dose-- norvasc 10 mg once per day. If this does not control blood pressure, I would next add HCTZ at 12.5 mg and increase to 25 mg if necessary. DOSAGE AND ADMINISTRATION Adults. The usual initial antihypertensive oral dose of NORVASC is 5 mg once daily, and the maximum dose is 10 mg once daily.
