I stopped taking Bystolic two days ago. My cardiologist told me that it wasn't necessary to taper off of it, since he was prescribing another beta blocker to replace it. I was taking 10mg Bystolic in the afternoon. He changed it to 12.6mg Coreg twice a day. So far I have not had any withdrawal symptoms.
The reason for his changing to Coreg was that my blood pressure still remained high while taking the Bystolic. I am now taking: 50mg HCTZ; 5mg Amlodipine; 25mg enalapril twice a day- along with 12.6mg Coreg twice a day.
I'll post again if I start having withdrawal symptoms from stopping Bystolic suddenly. Mabent
