Edit list (add/remove drugs)

Interactions between your drugs

Moderate

butalbital dronedarone

Applies to: Farbital (aspirin / butalbital / caffeine) and dronedarone

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of dronedarone, which is extensively and primarily metabolized by the isoenzyme. According to the prescribing information, administration with 600 mg once daily rifampin, a potent CYP450 3A4 inducer, decreased dronedarone systemic exposure (AUC) by 80% with no major change in the AUC of its active N-debutyl metabolite. Reduced efficacy of dronedarone may occur. The interaction has not been studied with other, less potent CYP450 3A4 inducers.

MANAGEMENT: The potential for diminished pharmacologic effects of dronedarone should be considered during coadministration with CYP450 3A4 inducers. Alternative treatments may be required if an interaction is suspected.

Minor

aspirin caffeine

Applies to: Farbital (aspirin / butalbital / caffeine) and Farbital (aspirin / butalbital / caffeine)

Information for this minor interaction is available on the professional version.

Drug and food interactions

Major

dronedarone food

Applies to: dronedarone

Do not consume grapefruit or grapefruit juice during treatment with dronedarone unless directed otherwise by your doctor. Grapefruit juice can increase the blood levels of dronedarone to dangerous levels. This may increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Talk to your doctor if you have any questions or concerns. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
