Short general description of Mellaril (Thioridazine)

Mellaril, also known by its generic name Thioridazine, is a medication primarily used to treat schizophrenia and other psychotic disorders. It belongs to a class of drugs known as phenothiazines, which act on certain chemicals in the brain to help restore the balance of neurotransmitters.

Thioridazine works by blocking the action of dopamine, a neurotransmitter that is believed to be involved in the development of psychotic symptoms. This drug is typically prescribed when other antipsychotic medications have not been effective or have caused intolerable side effects.

Thioridazine is available in tablet form and is usually taken orally. The dosage and duration of treatment will vary depending on the individual’s condition and response to the medication. It is important to follow the doctor’s instructions carefully when taking Mellaril to ensure its effectiveness and minimize potential side effects.
