Bijwerkingen

The following clinical significant adverse reactions are described elsewhere in the labeling:

Increased gastrointestinal toxicities with fluorouracil [see Warnings and Precautions ( 5.1 )] The most common adverse reactions (≥ 20%) in patients receiving high-dose methotrexate therapy with levoleucovorin rescue are stomatitis and vomiting. ( 6.1 ) The most common adverse reactions (>50%) in patients receiving levoleucovorin in combination with fluorouracil for metastatic colorectal cancer are stomatitis, diarrhea, and nausea.

6.1Clinical 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 practice. High-Dose Methotrexate Therapy Table 2 presents the frequency of adverse reactions which occurred during the administration of 58 courses of high-dose methotrexate 12 grams/m 2 followed by levoleucovorin rescue, for osteosarcoma, in 16 patients aged 6 to 21 years.

Most patients received levoleucovorin 7.5 mg every 6 hours for 60 hours or longer, beginning 24 hours after completion of methotrexate administration.

The trial failed to show superior overall survival with fluorouracil + levoleucovorin compared to fluorouracil + d,l -leucovorin. Patients were randomized to fluorouracil 370 mg/m 2 intravenously and levoleucovorin 100 mg/m 2 intravenously, both daily for 5 days, or to fluorouracil 370 mg/m 2 intravenously and d,l -leucovorin 200 mg/m 2 intravenously, both daily for 5 days. Treatment was repeated week 4 and week 8, and then every 5 weeks until disease progression or unacceptable toxicity.

6.2Postmarketing Experience

The following adverse reactions have been identified during post-approval use of levoleucovorin products. Because these adverse 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. The following have been reported:

Dermatologic : pruritus, rash
Respiratory : dyspnea
Other Clinical Events : temperature change, rigors, allergic reactions
