What is Emgality (galcanezumab-gnlm)?
Emgality is an FDA-approved monoclonal antibody medication classed as a calcitonin gene-related peptide receptor (CGRP) antagonist. By blocking the protein CGRP, it prevents the widening of blood vessels in your brain. Clinical studies show that this helps with migraine prevention and the treatment of the symptoms of a type of headache known as cluster headaches.
Emgality is indicated for the prevention of episodic migraine and chronic migraine headaches, and the treatment of episodic cluster headaches.
Emgality is available as a pre-filled syringe and a pre-filled pen with the following strengths:
- 120mg/ml single-dose pre-filled pen
- 100mg/ml single-dose pre-filled syringe
- 120mg/ml single-dose pre-filled syringe
The recommended dose for the preventive treatment of migraines is a 240mg loading dose (2 subcutaneous injections of 120mg) followed by once-monthly doses of 120mg. The recommended dose of Emgality is 300mg (3 subcutaneous injections or 100mg) at the start of the cluster period, then once a month until the cluster period ends.
Use Emgality as prescribed by your doctor. Your doctor should show you or your healthcare provider how to use your Pen or pre-filled syringe before your treatment begins.
Inject Emgality under the skin (subcutaneously) in your abdomen, thigh, buttocks, or the back of your upper arm. If you are using Emgality for the prevention of migraine headaches, you will inject it once a month. Your first dose (loading dose) is given as 2 separate injections right after one another. If you are using Emgality for the treatment of episodic cluster headaches, use it at the start of a cluster period and then monthly until the end of the cluster period.
If you miss a dose, take the missed dose of Emgality as soon as you remember. Inject your next dose after 1 month to get back on your monthly dosing schedule. Store Emgality away from direct sunlight in the refrigerator. You can store Emgality at room temperature for up to 7 days.
You are advised to read the full prescribing information and the instructions for use. Always speak with your healthcare provider for medical advice about any changes to your dose so they can monitor and evaluate your condition.
