Corgard Interactions

The following sections explain in detail the potentially negative interactions that can occur when Corgard is combined with any of the drugs listed above.

 

Combining Corgard with an alpha blocker can increase the risk of dangerously low blood pressure (hypotension). Check with your healthcare provider before combining such medications.

 

Combining Corgard with certain calcium channel blockers may cause a dangerously low blood pressure and (for verapamil or diltiazem) a slow heart rate (bradycardia) and heart failure. You may need to be monitored very closely if you take these medications together. In some cases, it is not recommended to combine Corgard with a calcium channel blocker.

 

Combining Corgard with certain arrhythmia medications may cause a dangerously slow heart rate (bradycardia). You may need to be monitored very closely if you take these medications together. In some cases, it is not recommended to combine Corgard with an arrhythmia medication.

 

If you take both clonidine and Corgard, stopping clonidine (without stopping the Corgard) could increase the risk of dangerously high blood pressure, strokes, and other serious problems. It is advised to stop taking Corgard several days before you gradually reduce the dose of clonidine. Do not attempt this without the approval and supervision of your healthcare provider.

 

Combining Corgard with digoxin may cause a dangerously slow heart rate (bradycardia). You may need to be monitored very closely if you take these medications together. In some cases, it is not recommended to combine Corgard with digoxin.
