Verapamil May Cause Heart Problems
Verapamil (Calan) is a blood pressure medication that is used "off-label" as a first-line preventive treatment for cluster headaches. However, when used for cluster headache, this drug may sometimes cause dangerous disturbances in heart rhythms (arrhythmia), according to a 2007 study in Neurology. The researchers recommend that patients who take verapamil should receive regular electrocardiograms to monitor for any signs of potential heart problems.
