FDA advises, “Please note levoleucovorin is available in ample quantities. There is potential for dosing errors when interchanging leucovorin and levoleucovorin. The dose of levoleucovorin is one-half the dose of racemic leucovorin injection (e.g., levoleucovorin 7.5 mg = racemic leucovorin 15 mg).” For more information on dosing and drug substitutions, refer to FDA guidelines and recommendations.
