How does Emgality work for migraine?
Emgality is a monoclonal antibody that targets CGRP. It attaches to the CGRP peptide ligand and blocks it from binding to the receptor. CGRP (calcitonin gene-related peptide) is a protein that has been discovered as a key component in some migraine attacks. CGRP is considered a neurotransmitter (a chemical messenger) and is present throughout the brain and body. Researchers have found that levels of CGRP are higher during a migraine attack, which led to the development of products to block the protein.
What are the possible side effects of Emgality?
Some patients in clinical trials experienced a hypersensitivity (allergic reaction) to Emgality, which can cause rash, itching, difficulty breathing, and swelling of the mouth, lips, tongue, or throat. The most common side effects experienced by patients taking Emgality in clinical trials were injection site reactions, such as soreness and redness.
These are not all the possible side effects of Emgality. Patients should talk to their doctor about what to expect with treatment with Emgality.
