Rythmol SR Uses

How Does It Work?

Rythmol SR belongs to a group of medications known as Class I antiarrhythmics. Class I antiarrhythmic medications block sodium channels in the heart. Rythmol SR works by slowing down the speed at which electrical impulses move through the heart, which helps stabilize the heart rhythm.
Rythmol SR is specially formulated so the medication is slowly released from the capsule over time. This allows Rythmol SR to be taken only two times a day, compared to three times a day with regular Rythmol.

Is It Safe for Children to Use Rythmol SR?

Rythmol SR has not been adequately studied in children, and is not approved for use in this age group (usually defined as individuals younger than 18 years old). Talk to your child's healthcare provider about the risks and benefits of using this medicine in children.

Can Older Adults Use It?

Older adults can use Rythmol SR. In clinical trials, 46 percent of people were 65 years of age or older. Those over the age of 65 did not respond any differently to the medication than those younger than age 65. However, some older adults may be more sensitive to the effects of this medication. Therefore, in general, older adults may need to be closely monitored during Rythmol SR treatment.

Off-Label Uses

On occasion, your healthcare provider may recommend this medication for something other than the conditions discussed in this article. This is called an "off-label" use. Rythmol SR may be prescribed off-label for the following uses:
  • Maintaining a normal heartbeat in people with atrial flutter or paroxysmal supraventricular tachycardia
  • Converting atrial fibrillation to a normal heartbeat
  • Treating certain arrhythmias of the ventricles
  • Treating heart rhythm problems in children
  • Treating Wolff-Parkinson-White syndrome.
