Prialt (ziconotide) is used to treat severe, long-term pain in adults. You can only use this medication if you can't take other pain medications or if other pain medications stopped working you. Prialt (ziconotide) is injected into the spinal fluid by a healthcare provider through an infusion pump. You can't use this medication if you have a history of psychosis because this medication can make your condition worse.
Severe, chronic (long-term) pain
Prialt (ziconotide) works to relieve pain by blocking the nerves from sending pain signals to the brain. All pain signals generally travel to the nerves in the spine before it reaches the brain, and Prialt (ziconotide) works directly at the spine to block these signals.

You might experience a change in mood, behavior, or mental state during your treatment with Prialt (ziconotide). This medication can cause symptoms of paranoia, aggressiveness, extreme excitement, depression, suicidal thoughts, confusion, memory problems, or speech problems. Let your provider know how Prialt (ziconotide) is affecting you.
Prialt (ziconotide) can make you less alert and aware of your surroundings. Don't participate in any activities, such as driving or operating machinery, during your treatment.
Let your provider know before starting Prialt (ziconotide) if you are taking other medications that also affect your level of alertness or your mental state. Taking Prialt (ziconotide) together with certain medications can cause more side effects.
Tell your provider if you experience new or worsening muscle pain, soreness, or weakness with or without dark urine. This might be a sign of muscle damage, which needs to be treated right away.
Prialt (ziconotide) can raise the risk of infections, so let your provider know if you experience nausea, vomiting, seizures, fever, headache, or stiff neck.
Speak to your provider if you are pregnant, planning to become pregnant, or breastfeeding before taking Prialt (ziconotide). It's not known if this medication can cause harm to your baby.
Prialt (ziconotide) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: History of psychosis | Elderly | Taking other CNS-depressant medications
Prialt (ziconotide) can't be used in people with a history of psychosis (losing touch with reality). This medication can affect your mental state and nervous system. Let your provider know right away if you have trouble concentrating, hallucinations (hearing or seeing things that aren't there), or changes in mood or mental state.
Since Prialt (ziconotide) can affect your mood, this medication can raise the risk of developing new or worsening current depression. Let your provider know if you have thoughts of wanting to harm yourself during your treatment.
Prialt (ziconotide) can also make you less alert and lead to symptoms of confusion, problems with memory, difficulty speaking or understanding language, abnormal thoughts, and forgetfulness. Your risk of these side effects is greater if you're taking other medications that also make you less alert, such as medications for seizures, psychosis, sleep, or blood pressure. And in rare cases, some people became unresponsive while receiving Prialt (ziconotide). Let your caregive or loved ones know of these possible side effects so they can contact your provider right away if you're not able to.
Risk factors: Infusion pump placed outside of the body
Injecting Prialt (ziconotide) into the spinal fluid can raise the risk of a type of brain and spinal cord infection called meningitis. Meningitis can develop when parts of your infusion pump is contaminated by bacteria. Let your provider know if you have any signs or symptoms of meningitis, such as fever, headache, stiff neck, weakness, confusion, nausea, vomiting, and seizures. If an infection occurs, your provider will remove the pump and catheter, and prescribe the appropriate antibiotics.
Prialt (ziconotide) can raise the level of a protein in the blood called creatine kinase (CK), which can happen during the first two months of treatment. CK is usually found in skeletal muscles, heart muscles, and brain tissues. A high level of CK in the blood might indicate a health problem or muscle damage. Your provider will monitor your CK levels periodically throughout your treatment. Let your provider know if you experience muscle pain, muscle weakness, muscle cramps, overall weakness, or lack of energy.
Risk factors: Stopping opioid medications suddenly
If you've been taking opioid medications before starting Prialt (ziconotide), ask your provider how you can stop taking them safely. If you stop opioid medications too suddenly, you might experience withdrawal symptoms including nausea, vomiting, anxiety, fast heart rate, yawning, sneezing, runny nose, or wide pupils. Prialt (ziconotide) isn't an opioid and it can't help ease any withdrawal symptoms.
Prialt (ziconotide) can lower your alertness and awareness level, so don't drive or operate any machinery during your treatment. Avoid any activities that require your full attention or coordination.
The dose is determined by your provider and will be given via an intrathecal (into the spinal fluid) device. The typical starting dose is 2.4 mcg/day and the maximum dose is 19.2 mcg/day.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
