Many of the side effects of antipsychotic medications are unpleasant and can make it hard for people to stick with medication. Antipsychotics can cause neurological side effects that interfere with normal movements and make it hard to feel calm or experience pleasure.
After a first episode of psychosis in schizophrenia and related disorders, stopping antipsychotics is considered when the patient has made a full recovery and been well for at least 12 months.
Antipsychotic drugs can cause various abnormal motor syndromes, but abruptly stopping them has been associated with the seemingly paradoxical development of similar motor syndromes, such as withdrawal dyskinesias, parkinsonian symptoms, dystonias, and neuroleptic malignant syndrome.
If you stop antipsychotics suddenly it can cause 'rebound psychosis'. This means that the symptoms of your illness return suddenly, and you may become unwell again. This is also known as 'relapse'. If you or your family or friends think you are becoming unwell again, you should speak to your doctor.
However, some patients are able to sustain a psychosis-free existence after the cessation of antipsychotics. Several studies show that only 25%–55% of patients with schizophrenia who stopped taking antipsychotic medication experienced the relapse of symptoms in the first 6 to 10 months after they stopped taking them.
Some people need to keep taking it long term. If you have only had one psychotic episode and you have recovered well, you would normally need to continue treatment for 1–2 years after recovery. If you have another psychotic episode, you may need to take antipsychotic medication for longer, up to 5 years.
For neurological, neuropsychological, neurophysiological, and metabolic abnormalities of cerebral function, in fact, there is evidence suggesting that antipsychotic medications decrease the abnormalities and return the brain to more normal function.
Previous research has also shown that the use of antipsychotics may raise the risk of metabolic syndrome in patients with schizophrenia. Metabolic syndrome has, in turn, been associated with heart disease and diabetes.
Both typical and atypical antipsychotics commonly cause side effects like drowsiness, dizziness, blurred vision, constipation, nausea, and vomiting, per the NIMH. These often go away. But the drugs can also cause serious long-term side effects.
They can cause movement disorders such as twitching and restlessness, sedation and weight gain, and lead to diabetes. Because of these side effects, antipsychotic drugs are usually only used to treat severe mental illnesses such as schizophrenia or bipolar disorder.
You may find it's possible to manage your symptoms, or to make a full recovery, without medication. If you are taking antipsychotics, you may also want to use other options to support your mental health, as well as your medication.
It is safest to come off slowly and gradually.
You should do this by reducing your daily dose over a period of weeks or months. The longer you have been taking a drug for, the longer it is likely to take you to safely come off it. Avoid stopping suddenly, if possible.
For people with schizophrenia, long-term antipsychotic use is usually accompanied by adverse effects such as weight gain, metabolic syndrome, diabetes, and ischemic heart disease, demonstrating their important role in increased mortality.
Antipsychotic medications are typically used to treat psychosis, a condition that involves some loss of contact with reality. People experiencing a psychotic episode often experience delusions (false beliefs) or hallucinations (hearing or seeing things others do not see or hear).
All antipsychotic medications are associated with an increased likelihood of sedation, sexual dysfunction, postural hypotension, cardiac arrhythmia, and sudden cardiac death. Primary care physicians should understand the individual adverse effect profiles of these medications.
Amongst the many adverse effects of the first generation, or 'typical' antipsychotics, the most disturbing was Tardive Dyskinesia, which involves uncontrollable movements of face, hands and feet [2].
So while treatment with some antipsychotics seems to increase intelligence, others reduce symptoms without that effect. Other medications that are known to cause improved cognitive functioning had no effect when combined with those antipsychotics.
Antipsychotics can cause the very symptoms they relieve, including depression, obsessive-compulsive disorder (OCD), anxiety, poorer cognition, agitation, mania, insomnia, and abnormal movements.
Results: Antipsychotics, as a group, increase weight and may lead to dry mouth and bad breath, cataracts, hirsutism, acne, and voice changes; they may disturb symmetry of gait and heighten the risk for tics and spasms and incontinence, potentially undermining a person's attractiveness.
Conclusions. Viewed together with data from animal studies, our study suggests that antipsychotics have a subtle but measurable influence on brain tissue loss over time, suggesting the importance of careful risk-benefit review of dosage and duration of treatment as well as their off-label use.
“I was particularly interested in how antipsychotics affect people's sense of themselves because although antipsychotics can reduce symptoms of psychosis, they also dampen down emotions, motivation, and sexual function, which are such important parts of what makes us what we are.”
The following structural brain changes appear to be caused by antipsychotic drugs. Decreased brain volume with associated increased volume of the ventricles. These changes appear to be caused both by the disease process and by antipsychotic drugs, making it difficult to differentiate their impacts.
you have the right to refuse a medication or to stop taking it, even if your doctor thinks this might make your mental health problem worse.
Of the atypical antipsychotics, risperidone is the weakest in terms of atypicality criteria.
