Interactions between your drugs

Major

posaconazole romiDEPsin

Applies to: Noxafil (posaconazole) and romidepsin

Consumer information for this interaction is not currently available.

CONTRAINDICATED: Coadministration with posaconazole may increase the plasma concentrations of CYP450 3A4 substrates that can prolong the QT interval, possibly resulting in QT prolongation and cases of torsade de pointes (TdP). The underlying mechanism is decreased clearance due to inhibition of CYP450 3A4 activity by posaconazole. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia). In addition, the extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s).

MANAGEMENT: Coadministration of posaconazole with CYP450 3A4 substrates that can prolong the QT interval is considered contraindicated.

Drug and food interactions

Moderate

posaconazole food

Applies to: Noxafil (posaconazole)

Food significantly increases the absorption of posaconazole from the tablet or suspension formulations. The manufacturer recommends that you take the tablet with food and the oral suspension during or immediately (within 20 minutes) after a full meal. If you cannot eat a full meal, you should take the oral suspension with a liquid nutritional supplement like Ensure or an acidic carbonated beverage like ginger ale. Do not take these medications on an empty stomach, as it may lead to inadequate blood levels and reduced effectiveness. Ask your doctor before using alcohol together with posaconazole from delayed release suspension formulations as this may cause an increase in side effects. Talk to your doctor or pharmacist if you have any questions on how to use the medication properly.
