Norvasc is a prescription medication commonly used to treat heart conditions such as high blood pressure and angina. It is a calcium channel blocker that works by relaxing blood vessels so the heart does not have to work as hard to pump blood throughout the body, according to MedlinePlus. Norvasc is not a curative medication, although it can help control the conditions it is used to treat. Always discuss your complete medical history with your doctor before taking Norvasc.
Hypotension
Because of its effects on the blood vessels, Norvasc can cause hypotension, or low blood pressure, according to the FDA. This effect is more likely to develop in people with severe aortic stenosis.
Worsening of Condition
People who are taking Norvasc to treat angina or after suffering a heart attack may developing a worsening of the condition after either starting drug therapy or increasing the dose, according to RXList online. A person with severe obstructive coronary artery disease is more likely to develop a worsening of their health condition.
Chest Pain
Chest pain is a rare but serious side effect of Norvasc. If you experience chest pain while using the drug, stop taking it and call your doctor immediately, MedlinePlus advises. Another rare but serious side effect that should be reported to your doctor immediately is changes to your normal heart rhythm, including a pounding, rapid or irregular heartbeat.
Fainting
Some people taking Norvasc may experience bouts of dizziness, lightheadness or headaches as a side effect, and this is no cause for concern. However, if you faint while taking the medication report it to your doctor immediately, MedlinePlus advises.
Fatigue
Fatigue is a possible side effect of Norvasc, according to Drugs.com. Because of this, you should use caution when driving or performing other tasks requiring concentration until you know how the medication will effect you.
Liver Disease
Norvasc is metabolized in the liver, which can have a detrimental effect on people with liver disease or liver failure. Because of this risk, the medication must be administered carefully under close supervision in patients with liver disease, according to the FDA.
