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.footnote 1
The medicine is placed into
the nostril on the same side as the headache. It can be repeated 15 minutes
later, if needed. Side effects can include a burning
sensation or numbness in the nose.
This medicine is available
only by prescription. This medicine may be used to treat cluster headaches when
other medicines have not helped.
