If concomitant use with CYP2D6 substrates with a narrow therapeutic index cannot be avoided, monitor for adverse reactions.
Clinical trials were conducted in patients receiving combination therapy with a 5-HT3 receptor antagonist and dexamethasone. It is not possible to correlate frequency of adverse events with rolaprepitant alone.
1% to 10%:
Central nervous system: Dizziness (6%)
Gastrointestinal: Decreased appetite (9%), hiccups (5%), dyspepsia (4%), stomatitis (4%), abdominal pain (3%)
Genitourinary: Urinary tract infection (4%)
Hematologic & oncologic: Neutropenia (7% to 9%), anemia (3%)
Disease-related concerns:
- Hepatic impairment: Avoid use in patients with severe hepatic impairment; if use cannot be avoided, monitor for adverse reactions related to rolapitant.
Concurrent drug therapy issues:
- Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information. Rolapitant 's inhibitory effect on CYP2D6 may persist for at least 7 days (or longer); increased plasma concentrations of certain CYP2D6 substrates may result in QT prolongation and torsades de pointes. Monitor for adverse reactions if concomitant use with CYP2D6 substrates with a narrow therapeutic index cannot be avoided. Avoid concurrent use with pimozide; concurrent use with thioridazine is contraindicated.
Adverse events were observed in some animal reproduction studies.
Rolapitant prevents delayed nausea and vomiting associated with emetogenic chemotherapy by selectively and competitively inhibiting the substance P/neurokinin 1 (NK1) receptor.

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience hiccups, abdominal pain, lack of appetite, dizziness, or nausea. Have patient report immediately to prescriber signs of infection, urinary retention, or severe loss of strength and energy (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
