Galcanezumab, sold under the brand name Emgality, is a medication used to prevent migraines and treat cluster headaches. It is given by injection under the skin. Benefits may take up to three months.

Common side effects include pain or redness at the site of injection. Other side effects may include allergic reactions. Safety in pregnancy is unclear. It is a monoclonal antibody that attaches to and blocks calcitonin gene-related peptide (CGRP), thereby helping blood vessels to return to their normal size.

Galcanezumab was approved for medical use in the United States and Europe in 2018. In the United Kingdom it costs the NHS about £450 per month as of 2021. This amount in the United States is about 580 USD.
