Antipsychotic medications are a critical tool in modern mental healthcare, helping to treat psychosis and schizophrenia. However, like any medication, they can have side effects, including physical and emotional ones. These can range from sexual problems to abnormal movements, and in rare cases, life-threatening neuroleptic malignant syndrome (NMS). One of the more common side effects of antipsychotics is muscle pain, which can be caused by conditions such as akathisia, dystonia, and tardive dyskinesia (TD). These conditions involve involuntary muscle contractions and abnormal movements that can sometimes be painful. TD, in particular, tends to be irreversible.

Antipsychotics can cause tardive dyskinesia (TD), which involves repetitive, involuntary muscle movements
Antipsychotics are a class of medication used to treat certain mental health conditions, such as schizophrenia and bipolar disorder. While they can be effective, they also carry the risk of side effects, one of which is tardive dyskinesia (TD).
TD is a movement disorder characterised by involuntary, repetitive muscle movements. It typically occurs in individuals taking long-term antipsychotic medication, although it can also develop after short-term use or even after discontinuing the medication. The condition usually appears within days or weeks of starting treatment, but it can sometimes take months to develop.
The exact cause of TD is not fully understood, but it is believed to be related to the effects of dopamine receptor-blocking agents (DRBAs) on the brain. Antipsychotics primarily affect the dopaminergic system, which is crucial for regulating movement, mood, and other functions. When DRBAs block dopamine receptors for an extended period, the brain may compensate by increasing the sensitivity of these receptors. This heightened sensitivity leads to overactivity in the dopaminergic pathways, resulting in involuntary movements.
The symptoms of TD can include grimacing, contorted facial expressions, rapid eye blinking, lip smacking, tongue thrusting or rolling, and involuntary vocalisations such as grunting or humming. Limb movements are typically jerky, writhing motions, and patients may also experience finger or foot tapping. In some cases, TD can cause respiratory distress, asphyxia, and choking due to the involvement of laryngeal and pharyngeal muscles.
The risk of developing TD is lower with atypical antipsychotics, and certain medications, such as clozapine, have been found to be effective in treating and even reversing TD symptoms. Other treatment options include VMAT inhibitors like deutetrabenazine and valbenazine, which have been proven safe and effective.

Dystonia, a condition causing painful and abnormal muscle contractions, can be caused by antipsychotics
Antipsychotics are a class of medication that can cause various side effects, including muscle pain. One such side effect is dystonia, a condition that causes painful and abnormal muscle contractions. Dystonia can develop shortly after beginning antipsychotic treatment or several months into treatment. It typically affects the head and neck area, causing abnormal postures or muscle spasms.
Dystonia is characterised by sustained or intermittent muscle contractions of muscle antagonists, resulting in relatively slow, twisting movements. These abnormal movements and postures may be generalised, involving the trunk and at least two other sites, or restricted to specific areas such as the neck, hand and forearm, or mouth. In some cases, dystonia may only be visible during activity and not at rest. While rare, life-threatening forms of dystonia can occur, such as stridor caused by laryngospasm.
The pathogenesis of dystonia induced by antipsychotics is not yet fully understood. However, it is suggested that the blockage of D2 receptors in the caudate, putamen, and globus pallidus may be a contributing factor. This explanation is supported by the observation that the prevalence of antipsychotic-induced dystonia decreases with age, as D2 activity reduces as individuals get older.
Younger male patients are more predisposed to developing dystonia as a side effect of antipsychotics, particularly with the use of newer atypical antipsychotics such as risperidone and ziprasidone. Additionally, patient-related risk factors, such as a history of acute dystonia, cocaine use, and age, can increase the likelihood of developing antipsychotic-induced dystonia.
If you experience dystonia as a side effect of antipsychotic medication, it is important to consult your doctor. They may recommend slowly weaning off the antipsychotic or prescribing an additional medication to alleviate the symptoms.

Parkinsonism, a neurological condition involving tremors, hypokinesia, and rigidity, can be caused by antipsychotics
Antipsychotic medications can cause involuntary muscle movements, including muscle spasms and contractions, which may be painful. These are known as movement disorders and can include akathisia, oculogyric crisis, dystonia, and tardive dyskinesia (TD). Parkinsonism, a neurological condition involving tremors, hypokinesia, and rigidity, can also be caused by antipsychotics.
Parkinsonism is a common side effect of antipsychotic drugs, especially in older adults. It typically appears within days to weeks of starting treatment, but there may be an onset delay of several months or more in rare cases. Parkinsonism tends to resolve within months of discontinuing the medication, but recovery can take weeks or months, and complete recovery is not certain. Up to 20% of older adults may suffer from persisting parkinsonism months after stopping antipsychotics, suggesting underlying neurodegeneration.
The symptoms of parkinsonism include slow movements and tremors, which can take the form of twitching, shaking, or quivering. These symptoms mimic those of Parkinson's disease, and it can be difficult to differentiate between the two conditions. In fact, many patients with drug-induced parkinsonism may be misdiagnosed with Parkinson's disease. In addition, neurological deficits in patients with drug-induced parkinsonism may be severe enough to affect daily activities and may persist for long periods even after stopping the medication.
Certain antipsychotics have been associated with a higher risk of causing parkinsonism, including typical antipsychotics such as chlorpromazine, promazine, haloperidol, perphenazine, fluphenazine, and pimozide. About 80% of patients taking typical antipsychotics exhibit more than one type of extrapyramidal side effect, which includes parkinsonism. Atypical antipsychotics, such as clozapine, have a lower risk of causing parkinsonism and may even be used to treat existing cases.
The development of parkinsonism as a result of antipsychotics is thought to be due to the blocking of dopamine receptors in the brain, particularly in the striatum and mesocortex. This creates a state equivalent to dopamine deficiency, which is responsible for the symptoms of parkinsonism.

Antipsychotics can cause oculogyric crisis, affecting the muscles controlling eye movements
Antipsychotic medications can cause oculogyric crisis, a condition that affects the muscles controlling eye movements. Oculogyric crisis (OGC) is characterised by episodes of eyeball uprolling with upward fixation, lasting several minutes, and resulting in anxiety. It is typically triggered by high-potency neuroleptic drugs, including antipsychotics, and is considered an acute dystonic reaction.
OGC can occur with both typical and atypical antipsychotics, although it is more commonly associated with typical antipsychotics. Certain antipsychotic medications, such as haloperidol, olanzapine, and amisulpride, have been implicated in triggering OGC. The condition usually develops within days or weeks of starting or increasing the dosage of these medications.
The symptoms of OGC can be distressing and interfere with daily life. In addition to the abnormal eye movements, individuals may experience jaw spasms, tongue protrusion, ocular pain, and a widely opened mouth. In some cases, OGC may also be accompanied by psychological symptoms, such as anxiety, agitation, paranoia, and compulsive thinking.
Treatment for OGC typically involves the use of oral anticholinergics, which can help stabilise the condition. In some instances, reducing the dosage or discontinuing the causative antipsychotic medication may be necessary. Switching to safer alternatives, such as clozapine, or combining treatments, such as risperidone and anticholinergics, have proven effective in managing OGC.
It is important to note that OGC is a rare side effect of antipsychotic medication. However, given the potential impact on an individual's well-being and daily functioning, it is crucial to be aware of this possible adverse reaction when taking antipsychotics.

Sexual problems, including breast development and spontaneous ejaculation, can be side effects of antipsychotics
Antipsychotics can cause a range of sexual side effects in both men and women. The drugs can increase the body's levels of a hormone called prolactin, which stimulates and maintains lactation and is involved in breast development. Raised prolactin levels can lead to a decrease in libido.
In women, raised prolactin levels can lead to an increase in breast size and irregular periods. Other sexual side effects in women include low sexual desire (22% prevalence), arousal or excitement problems (14%), and sexual pain (7%).
In men, raised prolactin levels can lead to impotence and the development of breasts. Men may also experience spontaneous ejaculation or priapism (a painful erection lasting several hours). Priapism requires urgent medical attention. Other sexual side effects in men include premature ejaculation (21%), erectile dysfunction (5%), and low sexual desire (5%).
Spontaneous ejaculation is a rare side effect of antipsychotics. Total inhibition of ejaculation is more common, followed by reduced ejaculatory volume and 'retrograde' ejaculation.
