NCT ID NCT06216886
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether Botox injections into the skin can reduce the number of painful attacks in people with trigeminal neuralgia, a severe facial pain condition. It includes 20 adults who have not gotten enough relief from medications or are not candidates for surgery. Participants will receive either Botox or a saltwater placebo to see if the treatment safely eases their pain.
