Used primarily in the prevention of migraine headaches, this compound acts as a serotonin and histamine receptor antagonist. It helps reduce the frequency and severity of migraine episodes when taken regularly. It is also prescribed for the management of other types of vascular headaches. Some patients benefit from its use in reducing appetite, making it occasionally useful in weight management under medical supervision. Additionally, it has been used off-label to help manage symptoms of nausea and vomiting, particularly in palliative care settings.
