Tambocor

Generic name: Flecainide acetate.

Tambocor is an anti-arrhythmic. It alters nerve impulses within the heart to regulate heartbeat. 

Quick Facts About Tambocor

Purpose

Used to treat certain heart rhythm irregularities, such as paroxysmal atrial fibrillation (sudden attack or worsening of irregular heartbeat in which upper chamber of the heart beats irregularly and very rapidly); and paroxysmal supraventricular tachycardia (sudden attack or worsening of abnormally fast but regular heart rate occurring intermittently).

Tambocor Dosage

Usually Tambocor therapy is started in the hospital. Once you are out of the hospital, you must follow your doctor’s instructions carefully or you are at risk for serious heartbeat disturbances.

  • Usual adult dose: 50 to 100 milligrams taken every 12 hours. Doctor may increase dose every 4 days by 50 milligrams every 12 hours until condition is stabilized. If you have alkaline urine as a result of being a vegetarian or have a kidney disorder, you may need a lower dosage, as Tambocor will be processed and eliminated at a slower pace in the body.
  • Usual child dose: not generally prescribed for children.
  • Missed dose: take as soon as possible, if within 6 hours of next dose. Otherwise, do not take missed dose; go back to regular schedule. Do not double doses.
