Norvasc is the brand name for the medication amlodipine. According to Drugs.com, an online drug reference, Norvasc is classified as a calcium channel blocker and used in the treatment of high blood pressure and chest pain. To receive the most benefit, patients may use Norvasc alone or in combination with other medications. The use of Norvasc requires a health care provider prescription.
Function
According to Mayo Clinic, Norvasc affects the way calcium enters the cells of the heart and blood vessels. This change in calcium flow relaxes the blood vessels and increases the amount of blood and oxygen delivered to the heart while reducing the amount of stress on the heart. Increased work or stress on the heart can cause damage to the blood vessels surrounding the brain, heart and kidneys. Mayo Clinic states the damage caused to blood vessels by an overworked heart can lead to stroke, heart attack and kidney failure.
Proper Use
Drugs.com states Norvasc can be taken with or without food. If Norvasc upsets the stomach, take it with food to reduce the irritation. Do not miss doses of Norvasc. If a dose is skipped, take the missed dose as soon as possible unless it is time for the next scheduled dose. Do not take two doses of Norvasc at the same time. Too much of this medication can cause an extreme drop in blood pressure.

Precautions
Mayo Clinic states regular health care provider appointments are necessary to follow up with the progress of Norvasc. Do not suddenly stop taking this medication. Abruptly stopping Norvasc can cause chest pain or a rise in blood pressure. According to Drugs.com, patients should avoid driving or using heavy equipment until they know how Norvasc will affect them. The elderly have an increased sensitivity to Norvasc and should use this medication cautiously. Safety for the use in children under the age of 6 has not been determined. Discuss the use of Norvasc with a health care provider prior to becoming pregnant. It is not known if Norvasc is excreted in breast milk so do not breastfeed while taking this medication.
