Interaction Effect
Increased digoxin plasma concentrations
Interaction Summary
In drug interaction studies, the concomitant administration of digoxin and telaprevir increased the AUC of digoxin by 85%. Digoxin therapy should be initiated at the lowest dose. Digoxin serum concentrations should be monitored closely and the digoxin dose titrated accordingly.

How To Manage Interaction
Concomitant use of digoxin and telaprevir may lead to increased digoxin plasma concentrations. When coadministered with telaprevir, initiate digoxin treatment at the lowest dose. Monitor serum digoxin concentrations and titrate the digoxin dose accordingly.
Mechanism Of Interaction
Unknown
Literature Reports
A) In drug interaction studies, the concomitant administration of digoxin and telaprevir resulted in an increase in digoxin AUC and Cmax. Patients (n=20) received telaprevir 750 mg every 8 hours for 11 days and a single dose of digoxin 2 mg. Comparing digoxin plus telaprevir versus digoxin administration alone, the ratio estimate for digoxin Cmax was 1.5 (90% confidence interval (CI), 1.36 to 1.65), and for AUC was 1.85 (90% CI, 1.7 to 2) .
Digoxin Overview
-
Digoxin is used to treat heart failure and abnormal heart rhythms (arrhythmias). It helps the heart work better and it helps control your heart rate.
Telaprevir Overview
-
Telaprevir is used along with two other medications (ribavirin [Copegus, Rebetol] and peginterferon alfa [Pegasys]) to treat chronic hepatitis C (an ongoing viral infection that damages the liver) in people who have not yet been treated for this condition or whose condition could not successfully be treated with ribavirin and peginterferon alfa alone. Telaprevir is in a class of medications called protease inhibitors. It works by decreasing the amount of hepatitis C virus (HCV) in the body. Telaprevir may not prevent the spread of hepatitis C to other people.

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.
