- Uncomfortable restlessness, known as akathisia.
- Sexual problems due to hormonal changes.
- Weight gain.
- A higher risk of getting diabetes.

Can antipsychotics cause eating disorders?
On the other hand, there is evidence to suggest that some antipsychotic medications can exacerbate pre-existing eating disorders or lead to a recurrence of binge-eating symptoms.
What is a side effect of most antipsychotic drugs?
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.
Can antipsychotics cause weight loss?
Antipsychotic switching, notably to aripiprazole or ziprasidone, may lead to weight loss, while switching to olanzapine or clozapine can worsen cardiometabolic status. However, clinicians should note that antipsychotic switching is only one strategy to mitigate adverse cardiometabolic effects of antipsychotics.
Which antipsychotic causes least weight gain?
Ziprasidone caused the least amount of weight gain. A meta-analysis by De Hert et al observed that the newer antipsychotics asenapine, iloperidone, paliperidone and lurasidone caused significant weight gain.
What happens when a normal person takes antipsychotics?
Side-effects of typical antipsychotics vary depending on the drug and may include drowsiness, agitation, dry mouth, constipation, blurred vision, emotional blunting, dizziness, stuffy nose, weight gain, breast tenderness, liquid discharge from breasts, missed periods, muscle stiffness or spasms.
What happens if you take too many antipsychotics?
The most common cardiovascular effects that occur after atypical antipsychotic overdose are tachycardia, mild hypotension, and prolongation of the QTc interval. Other clinical syndromes in overdose include neuroleptic malignant syndrome (NMS) and antimuscarinic delirium. Seizures may be observed.
What do antipsychotics do to the brain?
Blocking the action of dopamine. 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.
Is anorexia a form of psychosis?
The body image disturbance at the heart of anorexia nervosa is a false perception akin to the perceptual disorders found in schizophrenia. Additional psychotic features associated with eating disorders-usually transient-have been attributed to the effects of starvation and electrolyte imbalance.
Is anorexia a symptom of schizophrenia?
Binge eating disorders and night eating syndromes are frequently found in patients with schizophrenia, with a prevalence of approximately 10%. Anorexia nervosa seems to affect between 1 and 4% of schizophrenia patients.
Can medications cause eating disorders?
Drug-induced anorexia is an abnormal loss of appetite associated with the use of a medication or other drug. It may be associated with drug-induced nausea or vomiting. Many medications have been associated with drug-induced anorexia (see Drug Reaction Data below).
Does your brain go back to normal after antipsychotics?
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.
What antipsychotic has the least side effects?
Of the available atypical antipsychotics, clozapine and quetiapine have shown the lowest propensity to cause extrapyramidal symptoms. Although the risk of extra-pyramidal symptoms is lower with risperidone and olanzapine than with conventional antipsychotics, risk increases with dose escalation.
How long do antipsychotic side effects last?
For example, if you’re experiencing hallucinations, these could go away after just a few days of taking your meds. Some other symptoms, such as delusions, may take up to 6 weeks to be managed. Everyone responds a little differently to antipsychotic medication.
What mental health meds cause weight loss?

How do antipsychotics not gain weight?
Recommend metformin 250 mg 3 times a day, along with lifestyle modifications, to promote weight loss and decrease insulin resistance in patients who gain more than 10% of their pretreatment body weight on antipsychotic medications.
What bipolar meds cause weight loss?
All 5 patients responded to adjunctive topiramate for the treatment of the bipolar or schizoaffective disorder. The mean dose of topiramate was 195 mg/day (range, 100–375 mg/day). All patients lost a substantial amount of weight on topiramate. The average weight loss was 22 lb (10 kg; range, 8–56 lb [4–25 kg]).
Why do antipsychotics make you hungry?
Antipsychotic drugs, scientists showed, not only block dopamine signaling in the brain but also in the pancreas, leading to uncontrolled production of blood glucose-regulating hormones and, eventually, obesity and diabetes.
What is the best antipsychotic?
With respect to the incidence of discontinuation, clozapine was the most effective antipsychotic drug, followed by aripiprazole. As with the survival analysis for time to discontinuation, clozapine and aripiprazole were the top ranked.
What drugs can cause permanent psychosis?
The representative drugs that can cause psychosis are amphetamine, scopolamine, ketamine, phencyclidine (PCP), and lysergic acid diethylamide (LSD) .
Is brain shrinkage from antipsychotics reversible?
Meyer-Lindberg himself published a study last year showing that antipsychotics cause quickly reversible changes in brain volume that do not reflect permanent loss of neurons (see ‘Antipsychotic deflates the brain’)7.
How long should antipsychotics be taken?
Overall, antipsychotic maintenance treatment should be recommended for the mid term (i.e., 1‐3 years), since there is strong evidence supporting efficacy of antipsychotics in reducing relapses over this time frame.
Are antipsychotics toxic?
Overdose of antipsychotic medications is common. Antipsychotics are within the top 5 groups of substances reported to national poison control centers. There are nearly 50,000 calls to U.S Poison Centers regarding atypical antipsychotic overdose. Most of these were managed at health care facilities.
What happens when you stop taking antipsychotics?
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.
