4. Dizziness
This is a continuation of the previously mentioned side effect, as dizziness and slow heart rate often go together, though this is not necessarily always the case. Dizziness is a common side effect that may occur when starting calcium channel blockers or if blood pressure drops too much. Moving slowly between positions can help reduce the likelihood of experiencing dizziness while on CCB treatment. Speak with your doctor about how to manage this side effect in your daily life.
