Calan is used for:

Treating supraventricular tachycardia, a rhythm disturbance of the heart. It is also used for controlling heart rate response to other rhythm disturbances, specifically atrial fibrillation and atrial flutter. It may also be used for other conditions as determined by your doctor.

Calan is a calcium channel blocker. It works by slowing the electrical conduction in the heart, slowing heart rate, and/or normalizing heart rhythm.

you are allergic to any ingredient in Calan

you have certain heart problems (eg, left ventricular dysfunction, sick sinus syndrome, second- or third-degree heart block and do not have a pacemaker), very low blood pressure, or moderate to severe congestive heart failure (CHF)

you have atrial fibrillation or flutter and a pre-excitation syndrome (extra conduction pathway in the heart), such as Wolff-Parkinson-White (WPW) syndrome or Lown-Ganong-Levine (LGL) syndrome

you have shock due to serious heart problems

you are taking dofetilide, or you have taken disopyramide within the past 48 hours
