Why two NDCs? The FDA registers this code as 58468-4663-1 — 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 → 58468-4663-01. Same drug, same package — only the format differs.

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.

Medicare drug plans payPart D · quarterly No Part D plan price is available for this NDC in our data.
Medicare Part B allowsASP · J1786 $43.326 / J1786 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 58468-4663-01, 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.
📅 Q1 2025 – Q4 2025 · 4 quarters of data

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Cerezyme — 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 Cerezyme. 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 58468-4663-1, 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: 58468-4663-01, written without dashes as 58468466301. 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 58468-4663-01, the first segment (58468) is the labeler code FDA assigned to Genzyme Corporation; the middle segment (4663) 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 Genzyme Corporation. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Genzyme Corporation 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 J1786 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 ~2 min read

5 WARNINGS AND PRECAUTIONS Infusion-Associated Reactions (IARs) : If a severe IAR occurs, discontinue CEREZYME immediately and initiate appropriate medical treatment. ( 5.2 )

5.1Hypersensitivity Reactions Including Anaphylaxis Life-threatening hypersensitivity reactions, including anaphylaxis, have been reported in patients treated with enzyme replacement therapies, including CEREZYME. In addition, other hypersensitivity reactions have included pruritus, flushing, urticaria, angioedema, chest discomfort, dyspnea, cough, cyanosis, tachycardia, and hypotension [see Adverse Reactions (6.1) ] . Patients with antibody to imiglucerase have a higher risk of hypersensitivity reactions.

Conversely, not all patients with symptoms of hypersensitivity have detectable IgG antibody. Consider periodic monitoring of patients during the first year of treatment for IgG antibody formation [see Adverse Reactions (6.2) ] . Anaphylaxis has occurred during the early course of enzyme replacement therapy and after extended duration of therapy.

Administer CEREZYME under the supervision of a healthcare provider knowledgeable in the management of hypersensitivity reactions including anaphylaxis. Initiate CEREZYME in a healthcare setting with appropriate medical monitoring and support measures, including access to cardiopulmonary resuscitation equipment. If a severe hypersensitivity reaction (e.g., anaphylaxis) occurs, discontinue CEREZYME and immediately initiate appropriate medical treatment, including use of epinephrine.

Consider the risks and benefits of re-administering CEREZYME following severe hypersensitivity reactions (including anaphylaxis). If the decision is made to re-administer CEREZYME, consider decreasing the infusion rate and administering antihistamines, antipyretics, and/or corticosteroids. Monitor patients for the occurrence of new signs and symptoms of a severe hypersensitivity reaction.

If a mild or moderate hypersensitivity reaction occurs, consider decreasing the infusion rate, temporarily stopping the infusion, and/or administering antihistamines, antipyretics, and/or corticosteroids. Inform patients of the symptoms of life-threatening hypersensitivity reactions, including anaphylaxis and to seek immediate medical care should symptoms occur.

5.2Infusion-Associated Reactions Infusion-associated reactions (IARs) such as angioedema, pruritus, rash, urticaria, chest discomfort, chills, fatigue, infusion-site burning, infusion-site discomfort, infusion-site swelling, pyrexia and hypertension have been observed in patients treated with CEREZYME [see Adverse Reactions (6.1) ] . If a severe IAR occurs, discontinue CEREZYME and immediately initiate appropriate medical treatment. Consider the risks and benefits of re-administering CEREZYME following a severe IAR.

If a mild or moderate IAR occurs, consider decreasing the infusion rate, temporarily stopping the infusion, and/or administering antihistamines, antipyretics, and/or corticosteroids.

🤒 Adverse Reactions ~2 min read

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions Including Anaphylaxis [see Warnings and Precautions (5.1) ] Infusion-Associated Reactions [see Warnings and Precautions (5.2) ] Adverse reactions reported in adults and pediatric patients include back pain, chills, dizziness, fatigue, headache, hypersensitivity reactions, nausea, pyrexia, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Genzyme at 1-800-633-1610 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1Clinical Trials and Postmarketing Experience The following adverse reactions associated with the use of imiglucerase were identified in clinical studies or postmarketing reports. Because some of these reactions were 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. See Table 2 for adverse reactions occurring in adults and pediatric patients treated with CEREZYME in clinical trials and the postmarketing setting.

Table 2: Adverse Reactions in Adults and Pediatric Patients Treated with CEREZYME Adverse Reactions Nervous system disorders dizziness, headache Cardiac disorders tachycardia Vascular disorders cyanosis, Signs and symptoms suggestive of hypersensitivity reactions including anaphylaxis [see Warnings and Precautions (5.1) ] and other infusion-associated reactions [see Warnings and Precautions (5.2) ] . flushing, hypotension, hypertension Respiratory, thoracic and mediastinal disorders cough, dyspnea, pneumonia, pulmonary hypertension Gastrointestinal disorders abdominal pain, diarrhea, nausea, vomiting Immune system disorders anaphylaxis, hypersensitivity Skin and subcutaneous tissue disorders angioedema, pruritus, rash, urticaria Musculoskeletal and connective tissue disorders back pain General disorders and administration site conditions chest discomfort, chills, fatigue, infusion-site burning, infusion-site discomfort, infusion-site swelling, pyrexia

6.2Immunogenicity The observed incidence of anti-drug antibodies (ADA) is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of ADA in the studies described below with the incidence of ADA in other studies, including those of CEREZYME or of other imiglucerase products. Approximately 15% of patients treated and tested to date have developed IgG antibody to CEREZYME during the first year of therapy.

Patients who developed IgG antibody did so largely within 6 months of treatment and rarely developed antibodies to CEREZYME after 12 months of therapy. Approximately 46% of patients with detectable IgG antibodies experienced symptoms of hypersensitivity. Patients with antibody to CEREZYME have higher risk of hypersensitivity reaction [see Warnings and Precautions (5.1) ] .

Patients who developed IgG antibody to CEREZYME had increased elimination half-life compared to patients without antibody [see Clinical Pharmacology (12.3) ] .

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to CEREZYME during pregnancy. Pregnant women exposed to CEREZYME and health care providers are encouraged to contact the Gaucher patient registry at 1-800-745-4447, extension 15500 or visit www.registrynxt.com. Risk Summary Available data on more than 500 pregnancies from the international Gaucher Disease registry, postmarketing reports, published observational studies and case reports with CEREZYME or non–US-licensed imiglucerase use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes.

There are risks associated with symptomatic Type I Gaucher disease in pregnancy (see Clinical Considerations ) . No animal reproduction studies have been conducted with imiglucerase. The estimated background risk of major birth defects and miscarriage in 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. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Pregnancy may exacerbate existing Type 1 Gaucher disease symptoms or result in new disease manifestations.

Untreated symptomatic Type 1 Gaucher disease may lead to complications during pregnancy, including hepatosplenomegaly, which can interfere with the normal growth of a pregnancy and thrombocytopenia, which can lead to excessive bleeding.

8.2Lactation Risk Summary Available published literature suggests a small amount of imiglucerase is present in breast milk immediately following an infusion of imiglucerase. Published case reports and postmarketing reports of breastfed infants have not reported adverse effects due to CEREZYME exposure. There are no data available on the effects on milk production.

The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for CEREZYME and any potential adverse effects on the breastfed infant from imiglucerase or from the underlying maternal condition. Lactating women with Gaucher disease treated with CEREZYME should be encouraged to enroll in the Gaucher patient registry [see Use in Specific Populations (8.1) ] .

8.4Pediatric Use The safety and effectiveness of CEREZYME for the treatment of non-CNS manifestations of Type 1 or Type 3 Gaucher disease have been established in pediatric patients. Use of CEREZYME for the treatment of non-CNS manifestations of Type 1 Gaucher disease is supported by evidence from adequate and well-controlled trials in adults and pediatric patients 12 years of age and older and additional safety and efficacy data from an observational study of Type 1 Gaucher disease in pediatric patients [see Adverse Reactions (6.1) and Clinical Studies (14) ] .

Use of CEREZYME for the treatment of non-CNS manifestations of Type 3 Gaucher disease is supported by evidence from adequate and well-controlled trials in adults and pediatric patients 12 years of age and older with Type I Gaucher disease and additional safety and efficacy data from an observational study of Type 3 Gaucher disease in adults and pediatric patients [see Adverse Reactions (6.1) and Clinical Studies (14) ] .

8.5Geriatric Use Among the patients with Type 1 Gaucher disease in Study 3 [see Clinical Studies (14) ] who had hemoglobin or platelet count measurements 1 to 3 years after initiating CEREZYME (n = 1,053), 6% of patients were 65 and over and 1% were 75 and over. No overall differences in effectiveness of CEREZYME were observed between patients 65 years of age and older and younger adult patients with Type 1 Gaucher disease.

🧬 Clinical Pharmacology 212 words

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Gaucher disease is characterized by a deficiency of β-glucocerebrosidase activity, which results in accumulation of glucocerebroside in various tissues including liver, spleen, and bone marrow. The mannose sugars on imiglucerase mediate binding to and internalization by cells including macrophages. CEREZYME catalyzes the hydrolysis of glucocerebroside to glucose and ceramide.

12.2Pharmacodynamics No formal pharmacodynamic studies have been conducted with CEREZYME.

12.3Pharmacokinetics During one-hour intravenous infusions of four doses (7.5, 15, 30, 60 units/kg) of CEREZYME, steady-state enzymatic activity was achieved by 30 minutes. Following infusion, the half-life of plasma enzymatic activity ranged from 3.6 to 10.4 minutes. Plasma clearance ranged from 9.8 to 20.3 mL/min/kg (mean ± SD, 14.5 ± 4.0 mL/min/kg). The volume of distribution corrected for weight ranged from 0.09 to

0.15L/kg (mean ± SD, 0.12 ±

0.02L/kg). These variables do not appear to be influenced by dose or duration of infusion. However, only one or two patients were studied at each dose level and infusion rate.

Antidrug Antibody Effects on Pharmacokinetics In patients who developed IgG antibody to CEREZYME, an apparent effect on serum enzyme levels resulted in diminished volume of distribution and clearance and increased elimination half-life compared to patients without antibody [see Adverse Reactions (6.2) ] .

📋 Description 190 words

11 DESCRIPTION Imiglucerase is a hydrolytic lysosomal glucocerebrosidase-specific enzyme. It is an analogue of the human enzyme b-glucocerebrosidase (b-D-glucosyl-N-acylsphingosine glucohydrolase, E.C. 3.2.1.45), produced by recombinant DNA technology using mammalian cell culture (Chinese hamster ovary).

Purified imiglucerase is a monomeric glycoprotein of 497 amino acids, containing 4 N-linked glycosylation sites (Mr=60,430). Imiglucerase differs from placental glucocerebrosidase by one amino acid at position 495, where histidine is substituted for arginine. The oligosaccharide chains at the glycosylation sites have been modified to terminate in mannose sugars.

The modified carbohydrate structures on imiglucerase are somewhat different from those on placental glucocerebrosidase. CEREZYME (imiglucerase) for injection is intended for intravenous use. It is supplied as a sterile, nonpyrogenic, white to off-white lyophilized powder for reconstitution with Sterile Water for Injection, USP.

Each single-dose vial contains 424 units imiglucerase, mannitol (340 mg), polysorbate 80, NF (1.06 mg), and sodium citrates: disodium hydrogen citrate (36 mg) and trisodium citrate (104 mg). An enzyme unit (U) is defined as the amount of enzyme that catalyzes the hydrolysis of 1 micromole of the synthetic substrate para-nitrophenyl-b-D-glucopyranoside (pNP-Glc) per minute at 37°C. Reconstituted solutions have a pH of approximately 6.1.
