Prochlorperazine belongs to a group of medications known as the phenothiazine antipsychotics. It is sometimes referred to as a 'major tranquilliser'. It acts by blocking a variety of receptors in the brain, particularly dopamine receptors. Dopamine is involved in transmitting signals between brain cells. When there is an excess amount of dopamine in the brain it causes over-stimulation of dopamine receptors. These receptors normally act to modify behaviour and over-stimulation may result in psychotic illness. Prochlorperazine blocks these receptors and stops them becoming over-stimulated, thereby helping to control psychotic illness. Although prochlorperazine can be used in the control of psychotic conditions such as schizophrenia, it also affects receptors in an area of the brain that controls nausea and vomiting. For this reason, it is also useful in the treatment of nausea and vomiting, especially when it is caused by medication or radiation treatment. Prochlorperazine is also used to control symptoms such as nausea and dizziness which are caused by inner ear disorders. What is it used for? Anxiety (short term use) Disorders of the inner ear Mania Meniere's disease Nausea and vomiting Psychotic illness Schizophrenia Warning! Do not drink alcohol whilst taking this medicine.
