Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Eye: lacrimal duct stenosis, corneal disorders including keratitis Hepatobiliary: hepatic failure Immune System Disorders: angioedema Nervous System: toxic leukoencephalopathy Renal & Urinary: acute renal failure secondary to dehydration including fatal outcome Skin & Subcutaneous Tissue: cutaneous lupus erythematosus, severe skin reactions such as Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis (TEN), persistent or severe PPES can eventually lead to loss of fingerprints

5)]. Serious adverse reactions may still occur even if no DPYD variants are identified. Avoid use of capecitabine tablets in patients with certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency.

Withhold or permanently discontinue capecitabine tablets based on clinical assessment of the onset, duration, and severity of adverse reactions in patients with evidence of acute early-onset orunusually severe reactions. No capecitabine tablets dose has been proven safe for patients with complete DPD deficiency.

For patients with partial DPD deficiency, individualize the dosage and modify based on tolerability and intent of treatment. An FDA-authorized test for the detection of genetic variants of the DPYD gene to identifypatients at risk of serious adverse reactions with capecitabine tablets treatment is not currently available.

, which DPYD variant(s) they identify). 2 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 capecitabine tablets concomitantly with vitamin K antagonists, such as warfarin.

Clinically significant increases in PT and INR have been reported in patients who were on stable doses of oral vitamin K antagonists at the time capecitabine tablets was introduced. These events occurred within several days and up to several months after initiating capecitabine tablets and, in a few cases, within 1 month after stopping capecitabine tablets.

These events occurred in patients with and without liver metastases. 1) ]. 3 Cardiotoxicity Cardiotoxicity can occur with capecitabine tablets. Myocardial infarction/ischemia, angina, dysrhythmias, cardiac arrest, cardiac failure, sudden death, electrocardiographic changes, and cardiomyopathy have been reported with capecitabine tablets.

These adverse reactions may be more common in patients with a prior history of coronary artery disease. 5 )]. The safety of resumption of capecitabine tablets in patients with cardiotoxicity that has resolved have not been established.

4 Diarrhea Diarrhea, sometimes severe, can occur with capecitabine tablets. In 875 patients with metastatic breast or colorectal cancer who received capecitabine tablets as a single agent, the median time to first occurrence of grade 2 to 4 diarrhea was 34 days (range: 1 day to 1 year).

5 ) ]. 5 Dehydration Dehydration can occur with capecitabine tablets. Patients with anorexia, asthenia, nausea, vomiting, or diarrhea may be at an increased risk of developing dehydration with capecitabine tablets. Optimize hydration before startingcapecitabine tablets.

Monitor hydration status and kidney function at baseline and as clinically indicated. 5) ]. 6 Renal Toxicity Serious renal failure, sometimes fatal, can occur with capecitabine tablets. 3)]. Monitor renal function at baseline and as clinically indicated.

Optimize hydration before starting capecitabine tablets. 5 )]. 2 )]. Monitor for new or worsening serious skin reactions. Permanently discontinue capecitabine tablets for severe cutaneous adverse reactions. 8 Palmar-Plantar Erythrodysesthesia Syndrome Palmar-plantar erythrodysesthesia syndrome (PPES) can occur with capecitabine tablets.

6 months (range: 11 days to 1 year). 5 ) ]. 9 Myelosuppression Myelosuppression can occur with capecitabine tablets. 4% had grade 3 or 4 anemia. 8% had grade 3 or 4 thrombocytopenia, and 10% had grade 3 or 4 anemia. Necrotizing enterocolitis (typhlitis) has been reported.

Consider typhlitis in patients with fever, neutropenia and abdominal pain. Monitor complete blood count at baseline and before each cycle. 5 x 10 9 /L or platelet count <100 x 10 9 /L. 5 )]. 10 Hyperbilirubinemia Hyperbilirubinemia can occur with capecitabine tablets.

9%. Of the 566 patients who had hepatic metastases at baseline and the 309 patients without hepatic metastases at baseline, grade 3 or 4 hyperbilirubinemia occurred in 23% and 12%, respectively. Of these 167 patients with grade 3 or 4 hyperbilirubinemia, 19% had postbaseline increased alkaline phosphatase and 28% had postbaseline increased transaminases at any time (not necessarily concurrent).

The majority of these patients with increased transaminases or alkaline phosphatase had liver metastases at baseline. In addition, 58% and 35% of the 167 patients with grade 3 or 4 hyperbilirubinemia had pre- and postbaseline increased alkaline phosphatase or transaminases (grades 1 to 4), respectively.

Only 8% (n=13) and 3% (n=5) had grade 3 or 4 increased alkaline phosphatase or transaminases. In the 596 patients who received capecitabine tablets for metastatic colorectal cancer, the incidence of grade 3 or 4 hyperbilirubinemia was similar to that observed for the pooled population of patients with metastatic breast and colorectal cancer.

The median time to onset for grade 3 or 4 hyperbilirubinemia was 64 days and median total bilirubin increased from 8 µm/L at baseline to 13 µm/L during treatment with capecitabine tablets. Of the 136 patients with grade 3 or 4 hyperbilirubinemia, 49 patients had grade 3 or 4 hyperbilirubinemia as their last measured value, of which 46 had liver metastases at baseline.

In the 251 patients with metastatic breast cancer who receivedcapecitabine tablets with docetaxel, grade 3 hyperbilirubinemia occurred in 7% and grade 4 hyperbilirubinemia occurred in 2%. 5) ]. 5 )]. 11 Embryo-Fetal Toxicity Based on findings from animal reproduction studies and its mechanism of action, capecitabine tablets can cause fetal harm when administered to a pregnant woman.

Insufficient data is available on capecitabine tablets use in pregnant women to evaluate a drug-associated risk. 6 times the human exposure (AUC) in patients who received a dosage of 1,250 mg/m 2 twice daily, respectively. Advise pregnant women of the potential risk to a fetus.

Advise females of reproductive potential to use effective contraception during treatment with capecitabine tablets and for 6 months following the last dose. 12 Eye Irritation, Skin Rash, and Other Adverse Reactions from Exposure to Crushed Tablets In instances of exposure to crushed capecitabine tablets, the following adverse reactions have been reported: eye irritation and swelling, skin rash, diarrhea, paresthesia, headache, gastric irritation, vomiting and nausea.
