What You'll Learn
Paliperidone can cause muscle stiffness and tremors
Paliperidone is a medication used to treat psychotic disorders, including schizophrenia and schizoaffective disorder. It is also sometimes used to treat patients with dementia-related psychosis. It works by rebalancing dopamine and serotonin to improve thinking, mood, and behavior.
While paliperidone can be an effective treatment for many people, it may cause some unwanted side effects. One of these potential side effects is muscle stiffness. If you experience severe muscle stiffness while taking paliperidone, it is important to check with your doctor right away, as it could be a symptom of a serious condition called neuroleptic malignant syndrome (NMS). NMS is a rare but serious adverse effect of antipsychotics, which can lead to death if left untreated. Other symptoms of NMS include high fever, confusion, extreme sweating, and a fast heartbeat.
In addition to muscle stiffness, paliperidone may also cause muscle tremors. These tremors can be a sign of a condition called extrapyramidal symptoms (EPS), which can also include restlessness and stiffness. EPS can occur in newborns whose mothers took antipsychotics during the third trimester of pregnancy. Tardive dyskinesia (TD) is another movement disorder that has been associated with paliperidone use. TD is characterized by uncontrolled, slow or jerky movements of the face, tongue, or body. While TD can be permanent, paliperidone has been shown to have a lower risk of causing this side effect compared to older antipsychotics.
It is important to note that not everyone who takes paliperidone will experience muscle stiffness or tremors. However, if you do experience these or any other side effects, be sure to consult your doctor or healthcare provider for further guidance and support.

It can also cause extrapyramidal symptoms (EPS)
Paliperidone can cause extrapyramidal symptoms (EPS), which are abnormal muscle movements. EPS is a technical term for muscle-related side effects that can develop from taking paliperidone. Symptoms of EPS include restlessness, tremors, and stiffness. These symptoms can also manifest as uncontrolled movements, especially of the face, neck, and back. In addition, paliperidone can cause tardive dyskinesia (TD), which involves slow or jerky movements that the affected individual cannot control. TD often starts with tongue rolling or chewing movements in the mouth. TD can be permanent, and a doctor should be consulted if symptoms of TD are present.
Paliperidone can also cause EPS and/or TD in newborns when taken during the third trimester of pregnancy. Symptoms in newborns may include agitation, feeding disorder, hypertonia, hypotonia, respiratory distress, somnolence, and tremors. These effects may be temporary and resolve without treatment, but they can also be more severe and require hospitalization.
EPS and TD are both movement disorders that can develop as side effects of taking paliperidone. While TD typically involves slow or jerky movements, EPS can manifest as uncontrolled movements, restlessness, tremors, and stiffness. It is important to consult a doctor if any symptoms of EPS or TD are present, as they can have a significant impact on daily life and well-being.
In addition to EPS and TD, paliperidone can also cause neuroleptic malignant syndrome (NMS), a rare but serious condition that can be life-threatening. NMS is characterized by symptoms such as confusion, fever, extreme muscle stiffness, and sweating. Individuals experiencing any symptoms of NMS should seek immediate medical attention, as this condition can have severe consequences if left untreated.
While paliperidone can cause a range of movement-related side effects, it is important to note that the risk of developing TD may be lower compared to older antipsychotics. However, individuals taking paliperidone should be vigilant for any signs or symptoms of movement disorders and consult a healthcare professional if needed.

Paliperidone may cause neuroleptic malignant syndrome
Paliperidone is a medication that works in the brain to treat schizophrenia and schizoaffective disorder. It is also used to treat the symptoms of psychotic disorders. It is known as a second-generation antipsychotic (SGA) or atypical antipsychotic. While paliperidone can be effective, it may cause some unwanted effects.
Neuroleptic malignant syndrome (NMS) is a rare but severe and potentially fatal complication associated with the use of antipsychotic medications, including paliperidone. It is characterised by altered mental status, muscle rigidity, hyperthermia, and autonomic dysfunction. NMS requires urgent medical intervention as it can result in death if not treated appropriately.
The symptoms of NMS include confusion, fever, extreme muscle stiffness, and sweating. These symptoms may indicate NMS, and patients should contact their healthcare provider immediately if they occur. Other signs that may suggest NMS include difficulty breathing, a fast heartbeat, high or low blood pressure, seizures, and tiredness.
NMS associated with paliperidone has been reported very rarely. However, there is limited information available on the incidence and management of NMS associated with long-acting injectable (LAI) antipsychotics. More case studies are needed to fully understand the true incidence of NMS associated with LAI atypical antipsychotics.

It can increase the risk of falls and bone fractures
Paliperidone can increase the risk of falls and bone fractures. It can cause orthostatic hypotension, which is a sudden drop in blood pressure when standing up from sitting or lying down. This may increase the risk of falling. To prevent this, patients should take care not to get up too quickly. Paliperidone may also cause sedation, dizziness, and drowsiness, which can also lead to falls and bone fractures. The risk of falls is higher for people with conditions or other medications that could worsen these effects.
Paliperidone may also increase the risk of bone fractures by causing high prolactin levels, which can lead to osteoporosis. This is especially true for long-term use, as elevated prolactin levels over months or years can increase the risk of osteoporosis and bone fractures. Additionally, paliperidone can cause muscle stiffness, which can increase the risk of falling and bone fractures.
The use of alcohol or other medicines that affect the central nervous system (CNS) with paliperidone may worsen these side effects, including dizziness, drowsiness, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines, medicines for allergies or colds, sedatives, tranquilizers, sleeping medicines, medicines for depression, and anxiety medications. It is important for patients taking paliperidone to be cautious and avoid situations that could increase the risk of falling, such as exercising or being in hot weather, as paliperidone may also make it more difficult for the body to cool down, increasing the risk of heat stroke.
It is important for patients taking paliperidone to be aware of the risk of falls and bone fractures and to take precautions to avoid these outcomes. Patients should also be monitored regularly by their doctor to check for any unwanted effects and adjust the dosage or medication if necessary.

Paliperidone may cause tardive dyskinesia (TD)
Paliperidone, sold under the brand name Invega, is a second-generation antipsychotic medication that works in the brain to treat schizophrenia and schizoaffective disorder. It rebalances dopamine and serotonin to improve thinking, mood, and behaviour.
Paliperidone has a lower risk of causing TD compared to older antipsychotics such as Haldol (haloperidol). However, the risk still exists, especially with prolonged use. TD is a known side effect of antipsychotics, and paliperidone is no exception. While paliperidone has shown a lower propensity for causing TD compared to older antipsychotics, it is essential to be vigilant for any signs or symptoms indicative of TD when taking this medication.
In addition to TD, paliperidone may cause other side effects, including changes in heart rhythm, high blood sugar levels, high cholesterol, weight gain, blood disorders, and increased prolactin levels. Some common side effects include headache, insomnia, sleepiness, parkinsonism, dystonia, tremor, dizziness, restlessness, increased sweating, and trouble sleeping. It is important for patients taking paliperidone to be aware of these potential side effects and to consult their doctor if any adverse effects occur.
