Ankle swelling as a side effect of Norvasc


Norvasc (amlodipine besilate) is a medicine known as a calcium channel blocker . They contain compounds known as calcium channel antagonists, which relax blood vessels and lower blood pressure. This helps the heart pump blood throughout the body.

Although the drug is important in treating high blood pressure, Norvasc is known to cause side effects. One of the most common is ankle swelling caused by an abnormal accumulation of fluid in the tissues .

Abnormal tissue swelling or edema is a common side effect of this class of drugs, especially Norvasca. It usually occurs in the ankles and feet due to gravity, but it can also affect the arms and legs. The development of edema is highly dose dependent, meaning that higher doses make symptoms appear or get worse.

Other side effects of Norvasc include headaches, dizziness, fainting, dizziness , irregular heartbeat, chest pain, or fast heartbeat.

Do not stop taking Norvasc until you talk to your doctor. In some cases, you may be prescribed a diuretic ("water pill") to reduce swelling or simply reduce the dose. If symptoms persist, your healthcare provider may choose a different calcium channel blocker or a different class of medications.

It is important to note that ankle swelling is also a sign of heart failure and pulmonary hypertension . Therefore, Norvasc may not be the main cause of edema but, on the contrary, contributes to its development.


Norvasc is available in tablet form in 2.5, 5, and 10 milligram (mg) strengths .

The standard oral dose is 5 mg once a day, increased if necessary to a maximum dose of 10 mg once a day. People who are shorter, frail, elderly, or have liver problems should start with 2.5 mg and gradually increase as needed to get the desired response.

Never exceed the recommended daily dose. In fact, you can overdose on calcium channel blockers, which can lead to potentially serious side effects such as:

  • Constipation
  • Confusion
  • Drowsiness
  • Slow heartbeat
  • Speak slurred
  • Difficulty breathing
  • Soft spot
  • Nausea
  • High blood sugar

If you suspect an overdose, call the Poison Control Hotline at 1-800-222-1222, which is available 24 hours a day, seven days a week. Do not induce vomiting unless directed to do so by a trained toxicologist.

If the treatment is carried out in a timely manner, the chances of recovery are good. However, survival depends on several factors, including the type of medicine that is taken and the dose. For example, an overdose of verapamil, another calcium channel blocker, is especially dangerous .

As with any emergency, time is of the essence and you should seek help quickly as soon as you suspect you need it.

Get the word of drug information

If you experience ankle swelling or any other symptoms associated with Norvasc, contact your doctor immediately. Your healthcare provider can evaluate your symptoms and dosage, and make reasonable recommendations for continued treatment. Your doctor may also decide to stop or change your medication.

Also, it should be understood that, in general, calcium channel blockers can cause serious side effects, especially when taken in excess. These drugs are especially powerful and directly affect the heart and blood vessels.

If you suspect that you have taken too many of these medications, call emergency services immediately. You should also contact Poison Control and your healthcare professional and provide them with all the necessary information to facilitate prompt treatment.
