Lidocaine is an anesthetic medicine that is most often used
to numb an area of the body before a minor surgical procedure. Sometimes a 4%
lidocaine solution is used as nose drops to stop cluster headaches.
Lidocaine has a small effect on pain for most people with cluster headaches. But it rarely stops the pain completely.1
For anyone who endures frequent or severe migraines, preventing these painful headaches is a top concern. Experts don't know exactly what causes migraines. But they have been able to identify medications to help prevent them.
People with frequent or severe migraine attacks can sometimes help prevent migraines if they:
adopt lifestyle changes
avoid migraine triggers
take preventive medications
