Can blood pressure meds like guanfacine cause bradycardia?

Yes. Guanfacine can cause bradycardia in rare instances - approximately 3% of patients experience this. Bradycardia can be more pronounced when Guanfacine is used in combination with certain other medications, such as a beta blocker. It is important to discuss potential side effects with your doctor, because for certain patients, certain risks may be outweighed by potential benefits, and vice-versa.
