NCT ID NCT04406259
First seen Jan 11, 2026 · Last updated May 15, 2026 · Updated 18 times
Summary
This study looks at a heart medication called verapamil, which is also used to prevent cluster headaches. Because the doses needed for headaches are much higher than for heart conditions, the study checks how often it causes a mild heart block. Researchers will monitor 60 adults with cluster headaches using ECGs and blood tests to better understand and manage these side effects.
