Capecitabine
/api/v1/drug/capecitabineBoxed warning
SERIOUS ADVERSE REACTIONS OR DEATH IN PATIENTS WITH COMPLETE DPD DEFICIENCY and BLEEDING WITH CONCOMITANT USE OF VITAMIN K ANTAGONISTS Increased risk of serious adverse reactions or death in patients with complete DPD deficiency Test patients for genetic variants of DPYD prior to initiating capecitabine tablets unless immediate treatment is necessary. Avoid use of capecitabine tablets in patients with certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency [see Warnings and Precautions ( 5.1 )]. Increased risk of bleeding with concomitant use of Vitamin K antagonists Altered coagulation parameters and/or bleeding, including death, have been reported in patients taking c apecitabine tablets concomitantly with oral vitamin K antagonists, such as warfarin [see Warnings and Precautions ( 5.2 ) , Drug Interactions (7.2 ) ] . Clinically significant increases in prothrombin time (PT) and international normalized ratio (INR) have been reported in patients who were on stable doses of a vitamin K antagonist at the time capecitabine tablets was introduced. These events occurred in patients with and without liver metastases. Monitor INR more frequently and adjust the dose of the vitamin K antagonist as appropriate [see Drug Interactions (7.2) ] .
Mechanism of action
Sourced from openFDACapecitabine is metabolized to fluorouracil in vivo. Both normal and tumor cells metabolize fluorouracil to 5-fluoro-2’-deoxyuridine monophosphate (FdUMP) and 5-fluorouridine triphosphate (FUTP).

Warnings & precautions
Sourced from openFDA• Cardiotoxicity : May be more common in patients with a prior history of coronary artery disease. Withhold capecitabine tablets for cardiotoxicity as appropriate. The safety of resumption of capecitabine tablets in patients with cardiotoxicity that has resolved has not been established. ( 2.5 , 5.3 ) • Diarrhea : Withhold capecitabine tablets and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. ( 2.5 , 5.4 ) • Dehydration : Optimize hydration before starting capecitabine tablets. Monitor hydration status and kidney function at baseline and as clinically indicated. Withhold capecitabine tablets and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. ( 2.5 , 5.5 ) • Renal Toxicity : Monitor renal function at baseline and as clinically indicated. Optimize hydration before starting capecitabine tablets. Withhold capecitabine tablets and then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. ( 2.5 , 5.6 ) • Serious Skin Toxicities : Monitor for new or worsening serious skin reactions. Permanently discontinue capecitabine tablets in patients who experience a severe cutaneous adverse reaction. ( 5.7 ) • Palmar-Plantar Erythrodysesthesia Syndrome : Withhold capecitabine tablets then resume at same or reduced dose, or permanently discontinue, based on severity and occurrence. ( 2.5 , 5.8 ) • Myelosuppression : Monitor complete blood count at baseline and before each cycle.
Adverse reactions
Sourced from openFDAThe following clinically significant adverse reactions are described elsewhere in the labeling: Cardiotoxicity [see Warnings and Precautions ( 5.3 )] Diarrhea [see Warnings and Precautions ( 5.4 )] Dehydration [see Warnings and Precautions ( 5.5 )] Renal Toxicity [see Warnings and Precautions ( 5.6 )] Serious Skin Toxicities [see Warnings and Precautions ( 5.7 )] Palmar-Plantar Erythrodysesthesia Syndrome [see Warnings and Precautions ( 5.8 )] Myelosuppression [see Warnings and Precautions ( 5.9 )] Hyperbilirubinemia [see Warnings and Precautions ( 5.10 )] • Most common adverse reactions in patients who received capecitabine tablets as a single agent for the adjuvant treatment for colon cancer (>30%) were palmar-plantar erythrodysesthesia syndrome, diarrhea, and nausea. ( 6.1 ) • Most common adverse reactions (>30%) in patients with metastatic colorectal cancer who received capecitabine tablets as a single agent were anemia, diarrhea, palmar-plantar erythrodysesthesia syndrome, hyperbilirubinemia, nausea, fatigue, and abdominal pain. ( 6.1 ) • Most common adverse reactions (>30%) in patients with metastatic breast cancer who received capecitabine tablets with docetaxel were diarrhea, stomatitis, palmar-plantar erythrodysesthesia syndrome, nausea, alopecia, vomiting, edema, and abdominal pain. ( 6.1 ) • Most common adverse reactions (>30%) in patients with metastatic breast cancer who received capecitabine tablets as a single agent were lymphopenia, anemia, diarrhea, handand- foot syndrome, nausea, fatigue, vomiting, and dermatitis.
Use in specific populations
Sourced from openFDA• Lactation : Advise not to breastfeed. ( 8.2 ) • Hepatic Impairment : Monitor patients with hepatic impairment more frequently for adverse reactions. (8.7) 8.1 Pregnancy Risk Summary Based on findings in animal reproduction studies and its mechanism of action [see Clinical Pharmacology ( 12.1 )], capecitabine tablets can cause fetal harm when administered to a pregnant woman. Available human data with capecitabine tablets use in pregnant women is not sufficient to inform the drug-associated risk. In animal reproduction studies, administration of capecitabine to pregnant animals during the period of organogenesis caused embryolethality and teratogenicity in mice and embryolethality in monkeys at 0.2 and 0.6 times the exposure (AUC) in patients receiving the recommended dose of 1,250 mg/m 2 twice daily, respectively (see Data). Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Pharmacokinetics
Sourced from openFDA- Metabolism
- The AUC of capecitabine and its metabolite 5’-DFCR increases proportionally over a dosage range of 500 mg/m 2 /day to 3,500 mg/m 2 /day (0.2 to 1.4 times the approved recommended dosage). The AUC of capecitabine’s metabolites 5’-DFUR and fluorouracil increased greater than proportional to the dose.
Overdosage
Sourced from openFDAAdminister uridine triacetate within 96 hours for management of capecitabine tablets overdose. Although no clinical experience using dialysis as a treatment for capecitabine tablets overdose has been reported, dialysis may be of benefit in reducing circulating concentrations of 5’-DFUR, a low– molecular-weight metabolite of the parent compound.
