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.
Certain antipsychotics may cause various eye problems. These include: blurred vision and difficulty reading. a build-up of granular deposits in the cornea and lens.
Blocking inhibitory dopamine receptors with antipsychotics causes a vicious circle-;the brake comes off and insulin and glucagon release become unchecked, quickly desensitizing the body and further propagating hyperinsulimia, hyperglycemia and, eventually, obesity and diabetes.
Dopamine is a neurotransmitter, which means that it passes messages around your brain. Most antipsychotic drugs are known to block some of the dopamine receptors in the brain. This reduces the flow of these messages, which can help to reduce your psychotic symptoms.
Thus, early exposure to antipsychotic drugs may permanently alter neuronal development with a lasting impact on behavior.
When people who are prescribed antipsychotics for psychotic disorders stop taking them, some relapse, meaning that their psychosis returns. However, some patients are able to sustain a psychosis-free existence after the cessation of antipsychotics.
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.
Evidence of the rapidity at which antipsychotics can affect brain volume in humans was recently provided by Tost and associates. These investigators found a significant, reversible decrease in striatal volume in healthy subjects within 2 hours after they were treated intravenously with haloperidol.
Agitation and sedation: Some people feel “wired” and unable to stop moving when taking antipsychotics. This effect may be mistaken for a worsening of illness rather than a side-effect of the medication. These same drugs can also have the opposite effect, making people feel tired.
Dr Horowitz said: “In clinical practice, I often see patients perking up when they reduce their antipsychotic medication and telling me that they 'feel more themselves. ' It is also true that some people get worse when their drugs are reduced. What we need is more research to work out who benefits and who doesn't.
People who have psychotic episodes are often totally unaware their behaviour is in any way strange or that their delusions or hallucinations are not real. They may recognise delusional or bizarre behaviour in others, but lack the self-awareness to recognise it in themselves.
You might feel a sense of restlessness.
Antipsychotics may cause a side effect known as akathisia, which is a sense of motor restlessness that sometimes feels a lot like symptoms of anxiety.
In addition to weight gain, antipsychotics are also known to impair glucose metabolism, increase cholesterol and triglyceride levels and cause arterial hypertension, leading to metabolic syndrome.
Clozapine and olanzapine have the safest therapeutic effect, while the side effect of neutropenia must be controlled by 3 weekly blood controls. If schizophrenia has remitted and if patients show a good compliance, the adverse effects can be controlled.
The target symptoms of antipsychotic drugs include agitation, aggression, psychosis, and inappropriate behaviors ( Figure 1 ).
Antipsychotics can cause the very symptoms they relieve, including depression, obsessive-compulsive disorder (OCD), anxiety, poorer cognition, agitation, mania, insomnia, and abnormal movements.
Boredom relates to the experience of meaning, which itself encompasses relationships, roles and a sense of control. Furthermore, medication, particularly antipsychotics that block dopamine (which is important for experiencing motivation, pleasure and reward), may contribute to it.
All antipsychotics are generally effective, although differences exist in terms of efficacy but also in side effect profile. So far, all antipsychotics block the dopamine-2 (D2) receptor in the brain, including recently available antipsychotics such as lurasidone, cariprazine and brexpiprazole.
But according to a new study, long-term use of these drugs may also negatively impact brain structure. Share on Pinterest Researchers say long-term use of antipsychotic medications – particularly first-generation antipsychotics – may lead to gray matter loss in the brain.
Antipsychotics have long been known to have side effects — notably uncontrolled tremors (parkinsonism) and restless leg syndrome (akathisia) — that might be explained by reduction in brain volume. But decreasing brain volume could also be responsible for the beneficial effects of the drugs.
Some people find that complementary and alternative therapies help to manage their symptoms. For example, this may be aromatherapy, reflexology or acupuncture. Complementary therapies may also help manage some of the side effects of medication, if you decide to continue with it.
After symptom remission, continuation of antipsychotic treatment is associated with lower relapse rates and lower symptom severity compared to dose reduction/discontinuation. Therefore, most guidelines recommend continuation of treatment with antipsychotic medication for at least 1 year.
But with the right treatment, most people can live complete and fulfilling lives – thanks mainly to their antipsychotic medication. But of course, all medications have side-effects and for some people on antipsychotics these side-effects can range from mildly debilitating to life threatening.
