Summary
Most patients taking atypical antipsychotics report side effects like weight gain and tiredness. However, less than a quarter of these patients inform their doctor about these adverse events.
Area of Science:
- Pharmacology
- Patient-Reported Outcomes
- Psychiatry
Background:
- Atypical antipsychotics are widely prescribed for various psychiatric conditions.
- Understanding patient-reported side effects is crucial for treatment adherence and management.
- Real-world data offers valuable insights beyond clinical trial settings.
Purpose of the Study:
- To document and analyze patient-reported side effects associated with common atypical antipsychotic medications.
- To identify the most frequently experienced adverse events in a real-world patient population.
- To assess the rate at which patients report these side effects to their healthcare providers.
Main Methods:
- A cross-sectional survey was conducted among patients using atypical antipsychotics.
- Data was collected on the occurrence and type of side effects experienced.
- Patient-reported outcomes were tabulated for medications including aripiprazole, olanzapine, paliperidone, quetiapine, risperidone, and ziprasidone.
Main Results:
- 54% of 353 respondents reported experiencing at least one side effect from atypical antipsychotics.
- The most common side effects included weight gain/hunger, tiredness/lethargy, and coordination/muscle problems (tenderness, twitches, tremors).
- Less than 25% of patients who experienced side effects reported them to their physician.
Conclusions:
- Patient-reported side effects are common among individuals taking atypical antipsychotics.
- Weight gain, fatigue, and motor symptoms are prevalent adverse events.
- There is a significant underreporting of side effects by patients to their physicians, highlighting a potential gap in communication and management.

Antipsychotic Drugs: Therapeutic Uses and Side Effects
Antipsychotic drugs primarily block dopamine and serotonin receptors and cholinergic, adrenergic, and histaminergic receptors, thereby reducing hallucinations and delusions in conditions like schizophrenia. However, they can trigger unwanted extrapyramidal effects such as dystonias, Parkinson-like symptoms, and tardive dyskinesia.
Despite these side effects, antipsychotics are used therapeutically for various purposes, including managing schizophrenia, preventing nausea and vomiting, curbing...

Antipsychotic Drugs: Typical and Atypical Agents
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...
Psychosis and Antipsychotic Drugs: Overview
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic symptoms in all...
Pharmacovigilance
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Drug Therapy
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Psychosis: Goals of Pharmacotherapy
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...
