Paroxetine
If you are taking
Coreg and
paroxetine together, your body may metabolize Coreg differently than intended. This can cause an increased level of Coreg in your body. If you are taking both of these medicines, your healthcare provider may choose to monitor you more closely and/or adjust your Coreg dose, depending on your particular situation.
Quinidine
If you are taking Coreg and quinidine together, your body may metabolize Coreg differently than intended. This can cause an increased level of Coreg in your body. When using these medicines together, your healthcare provider may monitor you more closely and/or adjust your Coreg dose.
Propafenone
If Coreg and propafenone are taken together, your body may metabolize propafenone differently than intended. This can cause an increased level of the medication in your blood. When using these medicines together, your healthcare provider may choose to monitor you more closely and/or adjust your propafenone dose, depending on your particular situation.
Cyclosporine
Taking cyclosporine and Coreg together may cause your body to metabolize the cyclosporine differently than intended. This can cause an increased level of cyclosporine in your blood. Thus, if you are taking both of these medicines, your healthcare provider may choose to monitor you more closely and/or adjust your cyclosporine dose as needed.
Calcium Channel Blockers
If you are taking Coreg with a
calcium channel blocker, your
blood pressure may decrease too much or your heart rate may slow down dramatically. This can cause symptoms such as a spinning sensation (vertigo), lightheadedness, dizziness, or fainting. You are also at increased risk for developing
congestive heart failure. Your healthcare provider may choose to monitor your situation more closely and/or adjust your dose of these medicines to prevent this interaction.
