What do you have to consider before using it?

Do not use Prialt

  • If you are allergic (hypersensitive) to ziconotide or any of the other ingredients of Prialt.
  • If you are receiving an anticancer medicine into the space around your spinal cord.
Take special care with 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 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.
  • 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.
  • Not recommended for use in children and adolescents.

Taking other medicines

Please tell your doctor if you are taking or have recently taken any other medicines (for example, baclofen, clonidine, bupivacaine or propofol), including medicines obtained without a prescription. You may feel drowsy if you are given Prialt with certain other medicines used to treat pain.

Pregnancy and breast-feeding

If you are pregnant, think you may be pregnant, or are breast-feeding ask your doctor for advice before taking any medicine.

Prialt should not be used during pregnancy or breast-feeding unless clearly necessary.

Driving and using machines

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

How is it used?

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.

Prialt is given as a very slow continuous injection into the space surrounding the spinal cord. 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.

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 in dose increments of ? 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.

If you feel that you are still in too much pain while taking 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 use 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.

The following information is intended for medical or healthcare professionals only:

Instructions for use and handling

Prialt is supplied as a clear, colourless solution in single use vials. It should be inspected visually for particulate matter and discolouration prior to administration. The solution should not be used if discoloured or cloudy or if particulate matter is observed.

For single use only. Any unused solution should be discarded according to local regulations.

If dilution is required, Prialt must be diluted aseptically with preservative-free sodium chloride 9 mg/ml (0.9%) solution for injection before use. The concentration of the solution used in the infusion pump must be no lower than 5 ?g/ml ziconotide in an external pump and 25 ?g/ml in an internal pump.

Strict aseptic procedures must be used during the preparation and handling of the solution for infusion and refilling of the pump. The patient and health-care providers must be familiar with the handling of the external or internal infusion system and be aware of the need to guard against infection.

Prialt has been shown to be chemically and physically compatible with the implantable Synchromed pump and the external CADD-Micro pump at the concentration levels indicated above. Chemical and physical in-use stability has been demonstrated for 14 days at 37ºC in the Synchromed pump when the pump has not previously been exposed to the medicinal product. The initial fill must therefore be replaced after 14 days.

Prialt was stable for 60 days at 37°C in the Synchromed pump previously exposed to the medicinal product. Stability has been demonstrated for 21 days at room temperature in the CADD-Micro pump.

Specific instructions for using the pumps must be obtained from the manufacturer. CE marked pumps equivalent to the Synchromed and CADD-Micro pump should be used to deliver ziconotide. Pumps previously used to deliver other medicinal products must be washed out three times with sodium chloride 9 mg/ml (0.9%) solution for injection (preservative-free) before being filled with ziconotide. The introduction of air into the pump reservoir or cartridge should be minimized, as oxygen can degrade ziconotide.

Prior to initiation of therapy, an internal pump must be rinsed three times with 2 ml of the solution at 25 ?g/ml. The concentration of Prialt in a naïve pump may be reduced due to adsorption onto the surfaces of the device, and/or dilution by the residual space of the device. Because of this, after the first use of Prialt, the reservoir should be emptied and refilled after 14 days. Subsequently the pump should be emptied and refilled every 60 days.
