What Prialt is and What It is Used For

Prialt contains the active substance ziconotide which belongs to a group of medicines, called analgesics or ‘painkillers’. Prialt is used for the treatment of severe, long-term pain in adults who need a painkiller by intrathecal injection (injection into the space that surrounds the spinal cord and the brain).

What You Need to Know Before You are Given Prialt

You Should not be Given Prialt

  • If you are allergic to ziconotide or any of the other ingredients of this medicine (listed in section Contents of the pack and other information).
  • If you are receiving an anticancer medicine into the space around your spinal cord.

Warnings and Precautions

Talk to your doctor before you are given Prialt

  • The effects of long-term treatment of Prialt are uncertain at this time and the possibility of toxic effects on the spinal cord have not yet been ruled out. In case of a need for long term treatment, monitoring may be necessary (as decided by your doctor).
  • If you are receiving Prialt via a pump worn outside your body, it is important you check once daily for any signs of infection at the point where the tube enters your body.
  • If you observe any signs of infection around the tube, such as skin redness, swelling, pain or discharge, you must tell your doctor immediately and seek treatment for the infection.
  • If you develop any tenderness in the area around the tube without signs of infection, you should seek advice from your doctor as soon as possible as tenderness may be an early sign of infection.
  • If you are receiving Prialt via a pump worn outside your body and any part of the infusion tubing becomes disconnected, you must contact your doctor or nurse immediately.
  • If you have any of the following symptoms: high temperature, headache, stiff neck, tiredness, confusion, feeling sick, vomiting or occasional fits, these may be signs of meningitis. You must tell your doctor immediately if you experience any of the above symptoms.
  • If you notice any adverse change in your thinking, mood or memory, please tell your doctor.
  • If you are receiving chemotherapy please tell your doctor.
  • You may have an increased level of an enzyme called creatine kinase in your blood and although this does not usually cause any symptoms or problems, your doctor is likely to monitor its level. In addition, you may also occasionally experience muscular problems. If such is the case, you should immediately notify your doctor, as he/she may decide to halt your Prialt treatment.
  • Severe allergic reactions have not been seen in clinical studies so far, however it is not yet possible to say for certain that a severe allergic reaction will not happen when you are given Prialt. You should tell your doctor immediately if you experience any of the following symptoms after receiving your treatment; sudden wheeziness, difficulty in breathing, pain in the chest, swelling of eyelids, face or lips, rash or itching (especially affecting the whole body).
  • In patients that suffer from severe long term pain, there is a higher likelihood of suicide and attempted suicide than in the general population. Prialt may also cause or worsen depression in people that are already susceptible. If you are experiencing depression or have a history of depression please inform your healthcare professional before you are commenced on Prialt. If after starting Prialt you experience a worsening of your depression or have any other symptoms affecting your mood, please inform your healthcare professional.
  • You may experience drowsiness or may not be fully aware of your surroundings whilst receiving treatment. If this happens, you should immediately notify your doctor, as he/she may decide to halt your Prialt treatment.

Other Medicines and Prialt

Tell your doctor if you are taking, have recently taken or might take any other medicines (for example, baclofen used to treat muscle spasticity, clonidine used to treat high blood pressure, bupivacaine used for local anaesthesia, morphine used for pain, propofol used for general anaesthesia or any medicine which is administered by intrathecal injection (injection into the space that surrounds the spinal cord and the brain)). You may feel drowsy if you are given Prialt with certain other medicines used to treat pain.

Pregnancy and Breast-feeding

The use of Prialt has been reported to cause confusion and drowsiness. Ask your doctor for advice before you drive or operate machinery.

This medicinal product contains less than 1 mmol sodium (23 mg) per maximum recommended intrathecal dose (21.6 µg/day), i.e. essentially ‘sodium- free’.

How to Use Prialt

Your treatment with Prialt will be managed by a doctor who has experience of giving medicines into the space around the spinal cord, and in the use of internal and external infusion pumps.

The recommended starting dose is no more than 2.4 micrograms per day. Your doctor will adjust the dose of Prialt according to the severity of your pain by adding no more than 2.4 micrograms/day. The maximum dose is 21.6 micrograms/day. At the start of your treatment your doctor may increase your dose every 1 to 2 days or more. If needed, the dose may be decreased or injection stopped if the side effects are too great.

Prialt is given as a very slow continuous injection into the space surrounding the spinal cord (intrathecal use). The medicine will be administered continuously from a pump either implanted into your abdominal wall or placed externally in a belt pouch. Your doctor will discuss with you the kind of pump that will be most suitable for you and when you need to have your pump refilled.

If you feel that you are still in too much pain while receiving Prialt, or that the side effects are too great, talk to your doctor.

Before giving you Prialt, your doctor might decide to slowly stop giving you opiates (other types of medicinal product which are used to treat pain) into your spinal cord and instead replace with alternative pain medicinal products.

If You Receive More Prialt Than You Should

If you receive more Prialt than your doctor intended, you may feel unwell with signs such as confusion, problems with speech, word finding difficulties, excessive shaking, light-headedness, excessive sleepiness, feeling or being sick. If this happens, consult your doctor or hospital immediately.

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