6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions ( 5.2 )] Infusion Site Reactions [see Warnings and Precautions ( 5.3 )] Most common adverse reactions in adults (≥2%) are: fatigue, diarrhea, neutropenia, asthenia, anemia, peripheral neuropathy, leukopenia, dyspepsia, urinary tract infection, pain in extremity.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety of FOCINVEZ has been established from adequate and well-controlled studies of another intravenous formulation of fosaprepitant [see Clinical Studies ( 14 )] .
Below is a display of the adverse reactions of fosaprepitant in these studies.
The overall safety of intravenous fosaprepitant was evaluated in approximately 1800 adult and pediatric patients.
Adverse Reactions in Adults for the Prevention of Nausea and Vomiting Associated with MEC In an active-controlled clinical trial in patients receiving MEC, safety was evaluated in 504 patients receiving a single dose of intravenous fosaprepitant in combination with ondansetron and dexamethasone (intravenous fosaprepitant regimen) compared to 497 patients receiving ondansetron and dexamethasone alone (standard therapy).
The most common adverse reactions are listed in Table

5 WARNINGS AND PRECAUTIONS CYP3A4 Interactions: Fosaprepitant is a weak inhibitor of CYP3A4, and aprepitant, the active moiety, is a substrate, inhibitor, and inducer of CYP3A4;
see Full Prescribing Information for recommendations regarding contraindications, risk of adverse reactions, and dosage adjustment of FOCINVEZ and concomitant drugs.
( 4 , 5.1 , 7.1 , 7.2 ) Hypersensitivity Reactions (including anaphylaxis and anaphylactic shock) : May occur during or soon after infusion.
If symptoms occur, discontinue the drug.
Do not reinitiate FOCINVEZ if symptoms occur with previous use.
Like all medications, Focinvez can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
