Verteporfin: (Average) Use caution if coadministration of verteporfin with ketoconazole foam is important on account of the risk of elevated photosensitivity. Verteporfin is a gentle-activated drug utilized in photodynamic therapy; all patients handled with verteporfin can be photosensitive. Concomitant use of other photosensitizing brokers like ketoconazole foam may increase the chance of a photosensitivity reaction.
Chlorpheniramine; Hydrocodone; Phenylephrine: (Moderate) Consider a lowered dose of hydrocodone with frequent monitoring for respiratory depression and buy dihydrocodeine uk sedation if concurrent use of ketoconazole is necessary. It is strongly recommended to avoid this combination when hydrocodone is being used for cough. Hydrocodone is a CYP3A4 substrate, and coadministration with CYP3A4 inhibitors like ketoconazole can improve hydrocodone exposure leading to increased or prolonged opioid effects together with fatal respiratory depression, particularly when an inhibitor is added to a stable dose of hydrocodone. These results could possibly be extra pronounced in patients additionally receiving a CYP2D6 inhibitor. If ketoconazole is discontinued, hydrocodone plasma concentrations will decrease resulting in lowered efficacy of the opioid and potential withdrawal syndrome in a affected person who has developed bodily dependence to hydrocodone.

Medication which are recognized to prolong the QTc interval have an increased danger of ventricular arrhythmias. Ketoconazole has been associated with prolongation of the QT interval and torsade de pointes (TdP). (Reasonable) Monitor for corticosteroid-related adverse results during chronic concomitant use of inhaled or nasal budesonide and ketoconazole. Keep away from concomitant use of oral budesonide and ketoconazole. Budesonide is a CYP3A substrate and ketoconazole is a robust CYP3A inhibitor.

The entire absolute bioavailability of inhaled and nasal budesonide products ranges from 6% to 39% of the labeled dose.
