What are common side effects of the tranquilizer thioridazine (Mellaril)?

The common side effects of thioridazine (Mellaril), which is an antipsychotic medication, primarily include dyskinesia, muscle tremors, and abnormal movements of the mouth. These effects are linked to the drug's influence on the central nervous system and its impact on dopamine receptors. Thioridazine, like other medications in its class, can result in extrapyramidal symptoms due to the way it alters dopamine levels, leading to involuntary movements and motor control issues.

Dyskinesia refers to involuntary muscle movements that can affect various parts of the body, including the face and mouth. Muscle tremors are also a well-documented side effect of antipsychotic medications due to their action on the neurochemical systems in the brain. Abnormal movements of the mouth can manifest as tardive dyskinesia, a potential long-term effect of continued use of such medications.

The other options—such as increased blood pressure, brittle bones, and loss of hair—are not typical side effects associated with thioridazine. Instead, these symptoms can be related to other medical conditions or different medications, and they do not directly correlate with the known pharmacological effects of thioridazine.
