Interaction Effect
An increased risk of cycloSPORINE toxicity (renal dysfunction, cholestasis, paresthesias)
Interaction Summary
An average reduction in cycloSPORINE dose of 20% was required in renal transplant patients when carvedilol was added to therapy. Monitor cycloSPORINE concentrations closely after initiation of carvedilol and adjust dose as appropriate .

How To Manage Interaction
When carvedilol is used with cycloSPORINE, monitor cycloSPORINE concentrations closely after initiation of carvedilol and adjust dose as appropriate.
Mechanism Of Interaction
Inhibition of cycloSPORINE metabolism
Literature Reports
A) The effect of carvedilol on the dose of cycloSPORINE was studied in 21 renal transplant patients with chronic vascular rejection. In order to maintain therapeutic blood levels, the dose of cycloSPORINE was reduced an average of 20% after carvedilol therapy was added. The change in dose of cycloSPORINE was not seen consistently in all patients; some patients did not require any dosage adjustment. In addition, all patients were treated with other beta-blockers prior to initiation of carvedilol. Other drugs were administered concomitantly, including diltiazem, metoclopramide, allopurinol, ranitidine, and norfloxacin. It was postulated that carvedilol interfered with the metabolism of cycloSPORINE .
Carvedilol Overview
-
Carvedilol is used to treat heart failure (condition in which the heart cannot pump enough blood to all parts of the body) and high blood pressure. It also is used to treat people who have had a heart attack. Carvedilol is often used in combination with other medications. Carvedilol is in a class of medications called beta-blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure
-
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
Cyclosporine Overview
-
Cyclosporine and cyclosporine (modified) are used with other medications to prevent transplant rejection (attack of the transplanted organ by the immune system of the person who received the organ) in people who have received kidney, liver, and heart transplants. Cyclosporine (modified) is also used alone or with methotrexate (Rheumatrex) to treat the symptoms of rheumatoid arthritis (arthritis caused by swelling of the lining of the joints) in patients whose symptoms were not relieved by methotrexate alone. Cyclosporine (modified) is also used to treat psoriasis (a skin disease in which red, scaly patches form on some areas of the body) in certain patients who have not been helped by other treatments. Cyclosporine and cyclosporine (modified) are in a class of medications called immunosuppressants. They work by decreasing the activity of the immune system.

Definitions
Severity Categories
Contraindicated
These drugs, generally, should not be used together simultaneously due to the high risk of severe adverse effects. Combining these medications can lead to dangerous health outcomes and should be strictly avoided unless otherwise instructed by your provider.
Major
This interaction could result in very serious and potentially life-threatening consequences. If you are taking this drug combination, it is very important to be under close medical supervision to minimize severe side effects and ensure your safety. It may be necessary to change a medication or dosage to prevent harm.
Moderate
This interaction has the potential to worsen your medical condition or alter the effectiveness of your treatment. It's important that you are monitored closely and you potentially may need to make adjustments in your treatment plan or drug dosage to maintain optimal health.
Minor
While this interaction is unlikely to cause significant problems, it could intensify side effects or reduce the effectiveness of one or both medications. Monitoring for changes in symptoms and your condition is recommended, and adjustments may be made if needed to manage any increased or more pronounced side effects.
Onset
Rapid: Onset of drug interaction typically occurs within 24 hours of co-administration.
Delayed: Onset of drug interaction typically occurs more than 24 hours after co-administration.
Evidence
Level of documentation of the interaction.
Established: The interaction is documented and substantiated in peer-reviewed medical literature.
Theoretical: This interaction is not fully supported by current medical evidence or well-documented sources, but it is based on known drug mechanisms, drug effects, and other relevant information.
How To Manage The Interaction
Provides a detailed discussion on how patients and clinicians can approach the identified drug interaction as well as offers guidance on what to expect and strategies to potentially mitigate the effects of the interaction. This may include recommendations on adjusting medication dosages, altering the timing of drug administration, or closely monitoring for specific symptoms.
It's important to note that all medical situations are unique, and management approaches should be tailored to individual circumstances. Patients should always consult their healthcare provider for personalized advice and guidance on managing drug interactions effectively.
