Hi,
Sotalol belongs to the group of medications known as beta blockers that is used in the treatment of atrial
fibrillation and arrhythmia or irregular heart beat. It may cause bradycardia. Sotalol is not recommended to use in patients with significant bradycardia where
heart rate is less than 50 beats/min. According to some clinical studies, 13% of patients taking Sotalol may develop
sinus bradycardia or heart rate less than 60 beats/min.
So, if anyone experiences sinus bradycardia during taking this medication, he or she should stop taking this medication and inform the prescribing doctor promptly for
medical help, because bringing down the heart rate more, may cause dizziness and
lightheadedness. The prescribing doctor will change this medication and chose another medication for him or her.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Zubayer Alam, General and Family Physician
