Interactions between your drugs

Moderate

dronedarone sofpironium topical

Applies to: dronedarone and sofpironium topical

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inhibitors of CYP450 2D6 may increase the plasma concentrations of topical sofpironium, which has been shown to be partially metabolized by the isoenzyme. In a pharmacokinetic study in patients with primary axillary hyperhidrosis, sofpironium systemic exposure (AUC) and peak plasma concentration (Cmax) increased approximately 2-fold following concomitant use with the potent CYP450 2D6 inhibitor paroxetine at a 20 mg oral dose. Clinical data for sofpironium use in combination with other less potent CYP450 2D6 inhibitors are not available.

MANAGEMENT: Caution is advised when sofpironium topical is used concurrently with CYP450 2D6 inhibitors. Patients should be more closely monitored for adverse effects such as blurred vision, urinary retention, difficulty controlling body temperature in warm environments, and dry mouth.

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.
