A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Using erythromycin together with dalfopristin can affect the rhythm of your heart. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications. 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.

Professional:

GENERALLY AVOID: Based on in vitro inhibition data, coadministration with dalfopristin-quinupristin may increase the plasma concentrations of drugs that are substrates of the CYP450 3A4 isoenzyme, including certain agents that can cause prolongation of the QTc interval (e.g., cisapride, disopyramide, pimozide, quinidine, tacrolimus). High plasma levels of these agents have been rarely associated with ventricular arrhythmias including ventricular tachycardia, ventricular fibrillation, and torsade de pointes, as well as cardiac arrest and sudden death.

MANAGEMENT: Given the potential for serious and life-threatening adverse cardiac events associated with increased plasma levels of agents that may prolong the QTc interval, concomitant use with dalfopristin-quinupristin should be avoided if they are known to be substrates of CYP450 3A4.
