Which of the following is a common side effect of antipsychotic medications?

The choice highlighting weight gain, sedation, dizziness, and extrapyramidal symptoms is indeed a common side effect experienced by individuals taking antipsychotic medications.

Antipsychotics, particularly atypical ones, are known to influence neurotransmitter systems in the brain, particularly dopamine and serotonin. Weight gain is a significant concern associated with many antipsychotics due to their effects on metabolism and appetite regulation. Sedation can occur as these medications often have calming properties that can lead to increased drowsiness. Dizziness may arise as a side effect of changes in blood pressure or sedation. Extrapyramidal symptoms, which include tremors, rigidity, and medication-induced parkinsonism, are particularly associated with typical antipsychotics but can also occur with atypicals.

These side effects underscore the importance of monitoring for physical health changes in patients receiving antipsychotic treatment, balancing benefits with potential risks, and making necessary adjustments in treatment to support overall well-being.
