Stemetil, generically known as prochlorperazine, is a medication primarily used in the management and treatment of nausea, vomiting, dizziness, and vertigo associated with various conditions, including migraines and inner ear disorders. It belongs to a class of drugs known as phenothiazines, which work by blocking dopamine receptors in the brain. This action helps to control severe nausea and vomiting by preventing the brain from sending the signals that cause these symptoms. Stemetil is also used in psychiatric settings to manage the symptoms of schizophrenia and non-psychotic anxiety. However, it is not the first line of treatment for these conditions due to the risk of side effects, such as movement disorders. It is available in various forms, including tablets, liquid, and injections, allowing for flexible administration routes depending on the patient's needs and the severity of the symptoms.
