Why two NDCs? The FDA registers this code as 70121-1572-1 — a 5-4-1 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the package segment → 70121-1572-01. Same drug, same package — only the format differs.

📖 What it is MedlinePlus · NLM

Levoleucovorin injection is used in adults and children to prevent harmful effects of methotrexate (Trexall) when methotrexate is used to treat osteosarcoma (cancer that forms in bones). Levoleucovorin injection is also used to treat adults and children who have accidentally received an overdose of methotrexate or similar medications or who are not able to eliminate these medications properly from their bodies. Levoleucovorin injection is also used with fluorouracil (5-FU, a chemotherapy medication) to treat adults with colorectal cancer (cancer that begins in the large intestine) that has spr...

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer mLPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo $6.19 $108.35 / 17.5 ml
Medicare drug plans payPart D · quarterly No Part D plan price is available for this NDC in our data.
Medicare Part B allowsASP · J0641 $0.049 / J0641 unit
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🗺️ Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for 70121-1572-01, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.

📊 Medicare Part D spend CMS · PART D · 2025 (Q1-Q4)

Medicare Part D (outpatient prescription) spending for Levoleucovorin Calcium — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Levoleucovorin Calcium. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 70121-1572-1, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 70121-1572-01, written without dashes as 70121157201. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 70121-1572-01, the first segment (70121) is the labeler code FDA assigned to Amneal Pharmaceuticals LLC; the middle segment (1572) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (01) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Amneal Pharmaceuticals LLC. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Amneal Pharmaceuticals LLC is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J0641 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.

⚠️ Warnings and Cautions ~1 min read

5 WARNINGS AND PRECAUTIONS Hypercalcemia: Due to calcium content, inject no more than 16 mL (160 mg) of levoleucovorin solution intravenously per minute. ( 5.1 ) Increased Gastrointestinal Toxicities with Fluorouracil: Do not initiate or continue therapy with levoleucovorin and fluorouracil in patients with symptoms of gastrointestinal toxicity until symptoms have resolved. Monitor patients with diarrhea until it has resolved as rapid deterioration leading to death can occur.

( 5.2 , 7 ) Drug Interaction with Trimethoprim-Sulfamethoxazole: Increased rates of treatment failure and morbidity with concomitant use of d,l -leucovorin with trimethoprim-sulfamethoxazole for Pneumocystis jiroveci pneumonia in patients with HIV. ( 5.3 )

5.1Hypercalcemia Because of the calcium content of the levoleucovorin solution, inject no more than 16 mL (160 mg of levoleucovorin) intravenously per minute.

5.2Increased Gastrointestinal Toxicities with Fluorouracil Leucovorin products increase the toxicities of fluorouracil [see Drug Interactions (7) ] . Gastrointestinal toxicities, including stomatitis and diarrhea, occur more commonly and may be of greater severity and of prolonged duration. Deaths from severe enterocolitis, diarrhea, and dehydration have occurred in elderly patients receiving weekly d,l- leucovorin and fluorouracil.

Monitor patients for gastrointestinal toxicities. Do not initiate or continue therapy with levoleucovorin and fluorouracil in patients with symptoms of gastrointestinal toxicity until those symptoms have resolved. Monitor patients with diarrhea until resolved, as rapid deterioration leading to death can occur.

5.3Drug Interaction with Trimethoprim-Sulfamethoxazole The concomitant use of d,l- leucovorin with trimethoprim-sulfamethoxazole for the acute treatment of Pneumocystis jiroveci pneumonia in patients with HIV infection was associated with increased rates of treatment failure and morbidity [see Drug Interactions (7) ] .

🤒 Adverse Reactions ~2 min read

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Hypercalcemia [see Warnings and Precautions (5.1) ] Increased gastrointestinal toxicities with fluorouracil [see Warnings and Precautions (5.2) ] 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 ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Amneal Pharmaceuticals at 1-877-835-5472 or FDA at 1-800-FDA-1088 o r www.fda.gov/medwatch.

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. Table 2: Adverse Reactions with High-Dose Methotrexate Therapy Adverse Reactions Levoleucovorin n = 16 All Grades (%) Grades 3 to 4 (%) Gastrointestinal Stomatitis 38 6 Vomiting 38 0 Nausea 19 0 Diarrhea 6 0 Dyspepsia 6 0 Typhlitis 6 6 Respiratory Dyspnea 6 0 Skin and Appendages Dermatitis 6 0 Other Confusion 6 0 Neuropathy 6 0 Renal function abnormal 6 0 Taste perversion 6 0 Combination with Fluorouracil in Colorectal Cancer Table 3 presents the frequency of adverse reaction which occurred in 2 arms of a randomized controlled trial conducted by the North Central Cancer Treatment Group (NCCTG) in patients with metastatic colorectal cancer.

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.

7 DRUG INTERACTIONS

7.1Effects of Leucovorin Products on Other Drugs Antiepileptic Drugs Folic acid in large amounts may counteract the antiepileptic effect of phenobarbital, phenytoin and primidone and increase the frequency of seizures in susceptible children. It is not known whether folinic acid has the same effects; however, both folic and folinic acids share some common metabolic pathways. Monitor patients taking folinic acid in combination with antiepileptic drugs.

Fluorouracil Leucovorin products increase the toxicity of fluorouracil. Do not initiate or continue therapy with levoleucovorin and fluorouracil in patients with symptoms of gastrointestinal toxicity until those symptoms have resolved. Monitor patients with diarrhea until the diarrhea has resolved, as rapid deterioration leading to death can occur [see Warnings and Precautions (5.2) ].

Trimethoprim-Sulfamethoxazole The concomitant use of d,l -leucovorin with trimethoprim-sulfamethoxazole for the acute treatment of Pneumocystis jiroveci pneumonia in patients with HIV infection was associated with increased rates of treatment failure and morbidity in a placebo-controlled study [see Warnings and Precautions (5.3) ] .

👥 Use in Specific Populations ~1 min read

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary There are limited data with levoleucovorin use in pregnant women. Animal reproduction studies have not been conducted with levoleucovorin. Levoleucovorin is administered in combination with methotrexate or fluorouracil, which can cause embryo-fetal harm.

Refer to methotrexate and fluorouracil prescribing information for additional information. 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.

8.2Lactation Risk Summary There are no data on the presence of levoleucovorin in human milk or its effects on the breastfed infant or on milk production. Levoleucovorin is administered in combination with methotrexate or fluorouracil. Refer to methotrexate and fluorouracil prescribing information for additional information.

8.4Pediatric Use The safety and effectiveness of levoleucovorin have been established in pediatric patients for rescue after high-dose methotrexate therapy in osteosarcoma and diminishing the toxicity associated with overdosage of folic acid antagonists or impaired methotrexate elimination. Use of levoleucovorin in pediatric patients is supported by open-label clinical trial data in 16 pediatric patients 6 years of age and older, with additional supporting evidence from literature [see Clinical Studies (14.1) ]. The safety and effectiveness of levoleucovorin have not been established for the treatment of pediatric patients with advanced metastatic colorectal cancer.

8.5Geriatric Use Clinical studies of levoleucovorin in the treatment of osteosarcoma did not include patients aged 65 and over to determine whether they respond differently from younger patients. In the NCCTG clinical trial of levoleucovorin in combination with fluorouracil for the treatment of metastatic colorectal cancer, no overall differences in safety or effectiveness were observed between patients age 65 years and older and younger patients.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action High-Dose Methotrexate Therapy Levoleucovorin is the pharmacologically active isomer of 5-formyl tetrahydrofolic acid. Levoleucovorin does not require reduction by the enzyme dihydrofolate reductase in order to participate in reactions utilizing folates as a source of “one-carbon” moieties. Administration of levoleucovorin counteracts the therapeutic and toxic effects of folic acid antagonists such as methotrexate, which act by inhibiting dihydrofolate reductase.

Combination with Fluorouracil in Colorectal Cancer Levoleucovorin enhances the therapeutic and toxic effects of fluorouracil. Fluorouracil is metabolized to 5-fluoro-2'- deoxyuridine-5'-monophosphate (FdUMP), which binds to and inhibits thymidylate synthase (an enzyme important in DNA repair and replication). Levoleucovorin is converted to another reduced folate, 5,10-methylenetetrahydrofolate, which acts to stabilize the binding of FdUMP to thymidylate synthase and thereby enhancing the inhibition of thymidylate synthase.

12.3Pharmacokinetics The pharmacokinetics of levoleucovorin after intravenous administration of a 15 mg dose was studied in healthy subjects. The mean maximum serum total tetrahydrofolate (total-THF) concentrations was 1,722 ng/mL (CV 39%) and the mean maximum serum (6S)-5-methyl-5,6,7,8-tetrahydrofolate concentrations was 275 ng/mL (CV 18%) observed around 0.9 hours post injection. Distribution Exploratory studies show that small quantities of systemically administered leucovorin enter the cerebrospinal fluid (CSF), primarily as its major metabolite 5-methyltetrahydrofolate (5-MTHFA).

In humans, the CSF levels of 5-MTHFA remain 1-3 orders of magnitude lower than the usual methotrexate concentrations following intrathecal administration. Elimination The mean terminal half-life was 5.1 hours for total-THF and 6.8 hours for (6S)-5-methyl-5,6,7,8-tetrahydrofolate. Drug Interaction Studies The mean dose-normalized steady-state plasma concentrations for both levoleucovorin and 5-methyl-THF were comparable whether fluorouracil (370 mg/m 2 /day as an intravenous bolus) was given in combination with levoleucovorin (250 mg/m 2 and 1,000 mg/m 2 as a continuous intravenous infusion for 5.5 days) or with d,l -leucovorin (500 mg/m 2 as a continuous intravenous infusion for 5.5 days).
