How entrectinib is dosed
From the FDA label for Rozlytrek (application NDA218550). Other entrectinib products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.
Select patients for treatment based on the presence of ROS1 rearrangement(s) or NTRK gene fusion. ( 2.1 ) Evaluate left ventricular ejection fraction, serum uric acid levels and QT interval and electrolytes prior to ROZLYTREK initiation. ( 2.2 ) Select appropriate dosage form: oral capsules, capsules prepared as an oral suspension or oral pellets. ( 2.3 ) Use capsules prepared as suspension for enteral tube administration. Do not use pellets for enteral tube administration. ( 2.3 ) Administer ROZLYTREK capsules, capsules prepared as a suspension, or pellets once daily, with or without food. ( 2.4 ) Adult Dosage for ROS1- Positive Non-Small Cell Lung Cancer: 600 mg orally once daily. ( 2.5 ) Adult and Pediatric Dosage for NTRK Gene Fusion-Positive Solid Tumors: Adults: 600 mg orally once daily. ( 2.6 ) Pediatric Patients: Recommended dosage is based on age and body surface area (BSA) as shown below. ( 2.6 ) Age Recommended Daily Dosage >6 months ≤0.50 m 2 : 300 mg/m 2 0.51 to 0.80 m 2 : 200 mg 0.81 to 1.10 m 2 : 300 mg 1.11 to 1.50 m 2 : 400 mg BSA ≥1.51 m 2 : 600 mg once daily >1 month to ≤6 months 250 mg/m 2 once daily Modify dosage of ROZLYTREK if coadministration with moderate or strong CYP3A inhibitors cannot be avoided.

Entrectinib side effects
The following clinically significant adverse reactions are described elsewhere in the labeling: Congestive Heart Failure [see Warnings and Precautions (5.1) ] Central Nervous System Effects [see Warnings and Precautions (5.2) ] Skeletal Fractures [see Warnings and Precautions (5.3) ] Hepatotoxicity [see Warnings and Precautions (5.4) ] Hyperuricemia [see Warnings and Precautions (5.5) ] QT Interval Prolongation [see Warnings and Precautions (5.6) ] Vision Disorders [see Warnings and Precautions (5.7) ] The most common adverse reactions (≥ 20%) were fatigue, constipation, dysgeusia, edema, dizziness, diarrhea, nausea, dysesthesia, dyspnea, myalgia, cognitive impairment, increased weight, cough, vomiting, pyrexia, arthralgia, and vision disorders. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Genentech at 1-888-835-2555 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trial 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 practice. Data in WARNINGS AND PRECAUTIONS and below reflect exposure to ROZLYTREK in 355 patients, including 172 (48%) patients exposed for 6 months or longer and 84 (24%) patients exposed for 1 year or longer.

Entrectinib drug interactions
Moderate and Strong CYP3A Inhibitors : For adult and pediatric patients 2 years and older, reduce the dose of ROZLYTREK if coadministration of moderate or strong CYP3A inhibitors cannot be avoided. ( 2.8 , 7.1 ) For pediatric patients less than 2 years, avoid coadministration with ROZLYTREK. ( 7.1 ) Moderate and Strong CYP3A Inducers : Avoid coadministration with ROZLYTREK. ( 7.1 ) Drugs That Prolong QTc Interval : Avoid concomitant use with ROZLYTREK. ( 7.2 ) 7.1 Effect of Other Drugs on ROZLYTREK Moderate and Strong CYP3A Inhibitors Adults and Pediatric Patients 2 Years and Older Coadministration of ROZLYTREK with a strong or moderate CYP3A inhibitor increases entrectinib plasma concentrations [see Clinical Pharmacology (12.3) ], which could increase the frequency or severity of adverse reactions. Avoid coadministration of strong or moderate CYP3A inhibitors with ROZLYTREK. If coadministration is unavoidable, reduce the ROZLYTREK dose [see Dosage and Administration (2.8) , Clinical Pharmacology (12.3) ]. Pediatric Patients less than 2 Years Avoid coadministration of ROZLYTREK with moderate or strong CYP3A inhibitors [see Clinical Pharmacology (12.3) ] . Avoid grapefruit products during treatment with ROZLYTREK, as they contain inhibitors of CYP3A. Moderate and Strong CYP3A Inducers Coadministration of ROZLYTREK with a strong or moderate CYP3A inducer decreases entrectinib plasma concentrations [see Clinical Pharmacology (12.3) ], which may reduce ROZLYTREK efficacy. Avoid coadministration of strong and moderate CYP3A inducers with ROZLYTREK . 7.2 Drugs That Prolong QTc Interval QTc interval prolongation can occur with ROZLYTREK. Avoid coadministration of ROZLYTREK with other products with a known potential to prolong QT/QTc interval [see Warnings and Precautions (5.6) , Clinical Pharmacology (12.2) ] .

What people report to the FDA about entrectinib
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 528 reports naming entrectinib, and the FDA flagged 85% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- dizziness40 reports
- pancytopenia32 reports
- metastases to central nervous system28 reports
- renal impairment28 reports
- blood creatinine increased24 reports
- taste disorder22 reports
- nausea21 reports
- constipation20 reports
Read these as a signal, not a rate. A report does not mean entrectinib caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

Frequently asked questions
What is entrectinib?
Rozlytrek (Entrectinib) is a medication used to treat Non-Small-Cell Lung Carcinoma.
Can you take entrectinib with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run entrectinib against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does entrectinib come in?
Across the brands we track, entrectinib is currently marketed as capsule and oral pellets, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic entrectinib?
We do not currently list a generic-labelled entrectinib product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
