More Detail on Interactions With Lopressor
Digoxin
Both digoxin and
Lopressor slow the heart rate. Taking them together could increase the risk of a dangerously low heart rate (bradycardia). Your healthcare provider may need to monitor your heart rate more closely if you take these two medications together.
Reserpine
If you are taking Lopressor with reserpine, your
blood pressure may decrease too much or your heart rate may slow dramatically. This can cause symptoms such as a spinning sensation (vertigo), lightheadedness, dizziness, or fainting. If you are taking Lopressor and reserpine together, your healthcare provider may choose to monitor your situation more closely and/or adjust your doses of these medicines.
Clonidine (Catapres, Duraclon)
If you are taking Lopressor with clonidine but then stop using the clonidine, your blood pressure may increase dramatically. Make sure to talk with your healthcare provider about how these medicines can be stopped safely.
Amiodarone (Cordarone)
If you are taking Lopressor and amiodarone together, your body may metabolize Lopressor differently than intended. This can cause an increased level of Lopressor in your body. If you are using these medicines together, your healthcare provider may choose to monitor you more closely and/or adjust your Lopressor dose if needed.
Cimetidine (Tagamet)
If you are taking Lopressor and
cimetidine together, your body may metabolize Lopressor differently than intended. This can cause an increased level of Lopressor in your body. If you are using these medicines together, your healthcare provider may choose to monitor you more closely and/or adjust your Lopressor dose if needed.
