    Rythmol (propafenone) is only to be used to treat life-threatening abnormal atrial beats. It can lead to an increased risk of death in people who've had a heart attack. It can also cause new or worsened arrhythmias or heart failure, which can be fatal. Rythmol (propafenone) hasn't demonstrated that it prolongs survival in people who take it. For these reasons, it should only be used when no other options are available.

    This is a black box warning. The FDA requires this warning when there is a significant risk of serious or life-threatening effects that anyone taking the drug should consider.

Means that some groups have a high risk of experiencing this side effect
