1. What Cleviprex is and what it is used for

Cleviprex contains the active substance clevidipine.

Clevidipine is a calcium channel blocker. Calcium channel blockers are medicines which lower blood pressure.

Cleviprex is used to lower blood pressure in adult patients preparing for surgery, undergoing surgery or immediately after surgery.

2. What you need to know before you are given Cleviprex

Do not use Cleviprex:

  • if you are allergic (hypersensitive) to clevidipine, soybeans, soya-bean oil, soy products, peanut, eggs or egg products or to any of the other ingredients of Cleviprex
  • if you have a condition where you have extremely high levels of fat in your blood including acute inflammation of the pancreas or kidney problems
  • if you have a kidney disorder that causes loss of protein in urine

Check with your doctor if you are unsure.

Warnings and precautions

Talk to your doctor before using Cleviprex:

  • if you have a heart condition where the aortic valve in your heart does not open completely
  • if you have an abnormally large heart caused by narrow blood vessels (hypertrophic obstructive cardiomyopathy)
  • if you have a heart condition where a valve is narrowed (stenosis of the mitral valve)
  • if you have a tear in the main artery of the body (aortic dissection)
  • if you have a tumour of the gland on top of the kidney (adrenal gland) that causes high blood pressure (pheochromocytoma)
  • if you have had a heart attack
  • if you have a condition where your heart cannot increase in rate in order to compensate for reduced blood pressure such as
    • an electrical problem with your heart
    • you are fitted with a pacemaker

Other medicines and Cleviprex

Please tell your doctor if you are taking, have recently taken or might take any other medicines.

It is particularly important that you tell your doctor if you have been taking any medicines to lower your blood pressure.

Pregnancy and breast-feeding

You must tell the doctor if:

  • you are pregnant or think you may be pregnant
  • you are planning on becoming pregnant
  • you are breast-feeding

There is no adequate information on the use of Cleviprex in pregnant women. Cleviprex should not be used during pregnancy unless clearly necessary. Your doctor will decide whether or not this treatment is appropriate for you.

It is not known whether Cleviprex is excreted in breast-milk. If you are breast-feeding, the doctor will decide whether Cleviprex should be used.

Driving and using machines

Cleviprex is used to lower your blood pressure, which may make you feel light-headed or dizzy and could affect your ability to drive or use machines.

You must not drive or operate machinery until the effects of Cleviprex have worn off. Check with your doctor before leaving hospital if you are unsure.

Cleviprex contains soya oil

If you are allergic to peanut or soya, do not use this medicinal product.

This medicinal product contains less than 1 mmol sodium (23 mg) per vial, i.e. essentially ‘sodium-free’.

3. How Cleviprex is used

Cleviprex is for infusion (drip) into a vein. This is administered by a doctor.

Your treatment with Cleviprex will be supervised by a doctor as Cleviprex is administered in the hospital. The doctor will decide how much Cleviprex you receive and will prepare the medicine.

  • Throughout your treatment, the doctor will check your blood pressure
  • Before the start of infusion the doctor will tell you about the signs of allergic reaction
  • The dose and duration of infusion depends upon the kind of treatment you are undergoing


An infusion of Cleviprex should be started at 4 ml/hour (2 mg/hour) and increased as tolerated in doubling amounts (i.e. 4 to 8, 8 to 16, 16 to 32, 32 to 64 ml/hour [2 to 4, 4 to 8, 8 to 16, 16 to 32 mg/hour]) every 90 seconds.

Cleviprex will reduce blood pressure for most patients at doses up to 32 ml/hour (16 mg/hour).

Some patients may require a dose up to 64 ml/hour (32 mg/hour).

If you have more Cleviprex than you should

These doses are carefully checked by the doctor, so an overdose is very unlikely. In the event of taking too much Cleviprex, the infusion will be reduced or stopped.

An overdose of Cleviprex may make you feel light-headed or dizzy or may make your heart beat faster.

If you are concerned that you may have been given too much Cleviprex, talk to your doctor or other medical staff immediately.

If you forget to have Cleviprex

Since treatment with Cleviprex is administered and supervised by a doctor, this is very unlikely. If you are concerned that you may have missed a dose, talk to your doctor immediately.

While you are receiving Cleviprex

If you develop severe allergic reactions, like swelling of your face and/or throat or fever tell your doctor immediately.

If you have further questions on the use of this product, ask your doctor.
