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.

1 INDICATIONS AND USAGE Acetylcysteine Injection is indicated to prevent or lessen hepatic injury after ingestion of a potentially hepatotoxic quantity of acetaminophen in patients with acute ingestion or from repeated supratherapeutic ingestion (RSI). Acetylcysteine Injection is an antidote for acetaminophen overdose indicated to prevent or lessen hepatic injury after ingestion of a potentially hepatotoxic quantity of acetaminophen in patients with an acute ingestion or from repeated supratherapeutic ingestion (RSI) ( 1 ).

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION Pre-Treatment Assessment Following Acute Ingestion ( 2.1 ) : Obtain a plasma or serum sample to assay for acetaminophen concentration at least 4 hours after ingestion. If the time of acetaminophen ingestion is unknown: Administer a loading dose of acetylcysteine immediately. Obtain an acetaminophen concentration to determine need for continued treatment.

If the acetaminophen concentration cannot be obtained (or is unavailable or uninterpretable) within the 8-hour time interval after acetaminophen ingestion or there is clinical evidence of acetaminophen toxicity: Administer a loading dose of acetylcysteine immediately and continue treatment for a total of three doses over 21 hours. If the patient presents more than 8 hours after ingestion and the time of acute acetaminophen ingestion is known: Administer a loading dose of acetylcysteine immediately Obtain acetaminophen concentration to determine need for continued treatment If the patient presents less than 8 hours after ingestion and the time of acute acetaminophen ingestion is known and the acetaminophen concentration is known: Use the Rumack-Matthew nomogram ( Figure 1 ) to determine whether or not to initiate treatment with acetylcysteine ( 2.2 ) Nomogram for Estimating Potential for Hepatotoxicity from Acute Acetaminophen Ingestion ( 2.2 ) : See Full Prescribing Information for instructions on how to use the nomogram to determine the need for dosing.

Preparation and Storage of Diluted Solution Prior to Administration ( 2.3 ) : Acetylcysteine is hyperosmolar (2,600 mOsmol/L), therefore acetylcysteine must be diluted in sterile water for injection, 0.45% sodium chloride injection, or 5% dextrose in water injection prior to intravenous administration. See Full Prescribing Information for examples of osmolarity depending on the type of solution and acetylcysteine concentration. Recommended Adult and Pediatric Dosage ( 2.4 ) : Acetylcysteine is for intravenous administration only Total dosage of acetylcysteine is 300 mg/kg given intravenously as 3 separate doses and total recommended infusion time for 3 doses is 21 hours See Full Prescribing Information for weight-based dosage and weight-based dilution ( 2.4 ) See Full Prescribing Information for recommendations for continuing acetylcysteine treatment after 21 hours ( 2.2 ) Repeated Supratherapeutic Acetaminophen Ingestion ( 2.5 ) : Obtain acetaminophen concentration and other laboratory tests to guide treatment; Rumack-Matthew nomogram does not apply.

2.1Pre-Treatment Assessment and Testing Following Acute Acetaminophen Ingestion The following recommendations are related to acute acetaminophen ingestion. For recommendations related to repeated supratherapeutic exposure see Dosage and Administration ( 2.5 ) . Assess the history and timing of acetaminophen ingestion as an overdose.

The reported history of the quantity of acetaminophen ingested as an overdose is often inaccurate and is not a reliable guide to therapy. Obtain the following laboratory tests to monitor hepatic and renal function and electrolyte and fluid balance: aspartate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin, international normalized ratio (INR), creatinine, blood urea nitrogen (BUN), blood glucose, and electrolytes. Obtain a plasma or serum sample to assay for acetaminophen concentration at least 4 hours after ingestion.

Acetaminophen concentrations obtained earlier than 4 hours post-ingestion may be misleading as they may not represent maximum acetaminophen concentrations. If the time of acute acetaminophen ingestion is unknown: Administer a loading dose of acetylcysteine immediately [ see Dosage and Administration ( 2.4 ) ]. Obtain an acetaminophen concentration to determine need for continued treatment [ see Dosage and Administration ( 2.2 ) ].

If the acetaminophen concentration cannot be obtained (or is unavailable or uninterpretable) within the 8-hour time interval after acetaminophen ingestion or ther… [Excerpted — this section continues on DailyMed.]

⛔ Contraindications 35 words ▾

4 CONTRAINDICATIONS Acetylcysteine Injection is contraindicated in patients with a previous hypersensitivity reaction to acetylcysteine [ see Warnings and Precautions ( 5.1 ) ]. Patients with a previous hypersensitivity reaction to acetylcysteine ( 4 )

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions, Including Hypotension, Wheezing, Shortness of Breath and Bronchospasm: Observe patients during and after the infusion; immediately discontinue infusion if a serious reaction occurs and initiate appropriate treatment. Acetylcysteine infusion may be carefully restarted after treatment of hypersensitivity has been initiated ( 5.1 ). Fluid Overload: Total volume administered should be reduced for patients weighing less than 40 kg and for those requiring fluid restriction ( 5.2 ).

5.1Hypersensitivity Reactions Serious acute hypersensitivity reactions during acetylcysteine administration including rash, hypotension, wheezing, and/or shortness of breath, have been observed in patients receiving intravenous acetylcysteine for acetaminophen overdose and occurred soon after initiation of the infusion [ see Adverse Reactions ( 6.1 ) ]. If a severe hypersensitivity reaction occurs, immediately stop the infusion of acetylcysteine and initiate appropriate treatment. One patient with asthma developed bronchospasm and died after intravenous administration of acetylcysteine.

Acetylcysteine should be used with caution in patients with asthma, or where there is a history of bronchospasm. Patients with asthma should be closely monitored during initiation of acetylcysteine therapy and throughout acetylcysteine therapy. Acute flushing and erythema of the skin may occur in patients receiving acetylcysteine intravenously.

These reactions usually occur 30 to 60 minutes after initiating the infusion and often resolve spontaneously despite continued infusion of acetylcysteine. If a reaction to acetylcysteine involves more than simply flushing and erythema of the skin, it should be treated as a hypersensitivity reaction. Management of less severe hypersensitivity reactions should be based upon the severity of the reaction and include temporary interruption of the infusion and/or administration of antihistaminic drugs.

The acetylcysteine infusion may be carefully restarted after treatment of the hypersensitivity symptoms has been initiated; however, if the hypersensitivity reaction returns upon re-initiation of treatment or increases in severity, acetylcysteine should be discontinued and alternative patient management should be considered.

5.2Fluid Overload The total volume of acetylcysteine administered should be adjusted for patients less than 40 kg and for those requiring fluid restriction. To avoid fluid overload, the volume of diluent should be reduced as needed [ see Dosage and Administration ( 2 ) ]. If volume is not adjusted fluid overload can occur, potentially resulting in hyponatremia, seizure and death.

Intravenous administration of acetylcysteine can cause fluid overload, potentially resulting in hyponatremia, seizure and death. To avoid fluid overload, use the recommended dilution shown in Tables 2 , 3 and 4 [ see Dosage and Administration ( 2.4 ) ].

🤒 Adverse Reactions ~3 min read ▾

6 ADVERSE REACTIONS Most common adverse reactions (greater than 2%) are rash, urticaria/facial flushing and pruritus ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Akorn Operating Company LLC at 1-800-932-5676 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1Clinical Studies 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. In the literature the most frequently reported adverse reactions attributed to intravenous acetylcysteine administration were rash, urticaria and pruritus. The frequency of adverse reactions has been reported to be between 0.2% and 21%, and they most commonly occur during the initial loading dose of acetylcysteine.

Loading Dose/Infusion Rate Study In a randomized, open-label, multi-center clinical study conducted in Australia in patients with acetaminophen poisoning, the rates of hypersensitivity reactions between a 15-minute and 60-minute intravenous infusion for the 150 mg/kg loading dose of acetylcysteine were compared. The incidence of drug-related adverse reactions occurring within the first 2 hours following acetylcysteine administration is presented in Table 5 . Overall, 17% of patients developed an acute hypersensitivity reaction (18% in the 15-minute infusion group; 14% in the 60-minute infusion group) [ see Warnings and Precautions ( 5.1 ), Clinical Studies ( 14 ) ].

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary Limited published case reports and case series of pregnant women exposed to acetylcysteine during various trimesters are not sufficient to inform any drug associated risk. Delaying treatment of acetaminophen overdose may increase the risk of maternal or fetal morbidity and mortality [ see Clinical Considerations ]. Reproduction studies in rats and rabbits following oral administration of acetylcysteine during the period of organogenesis at doses similar to the total intravenous dose (based on the body surface area) did not cause any adverse effects to the fetus.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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 Acetaminophen and acetylcysteine cross the placenta.

Delaying treatment in pregnant women with acetaminophen overdose and potentially toxic acetaminophen plasma levels may increase the risk of maternal and fetal morbidity and mortality. Data Animal Data Reproduction studies have been performed following administration of acetylcysteine during the period of organogenesis in rats at oral doses up to 2,000 mg/kg/day (1.1 times the recommended total human intravenous dose of 300 mg/kg based on body surface area comparison) and in rabbits at oral doses up to 1,000 mg/kg/day (1.1 times the recommended total human intravenous dose of 300 mg/kg based on body surface area comparison).

No adverse developmental outcomes due to acetylcysteine were observed.

8.2Lactation Risk Summary There are no data on the presence of acetylcysteine in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for acetylcysteine and any potential adverse effects on the breastfed child from acetylcysteine or from the underlying maternal condition. Clinical Considerations Based on the pharmacokinetic data, acetylcysteine should be nearly completely cleared 30 hours after administration.

Breastfeeding women may consider pumping and discarding their milk for 30 hours after administration.

8.4Pediatric Use Safety and effectiveness of acetylcysteine in pediatric patients have not been established by adequate and well-controlled studies. Use of acetylcysteine in pediatric patients 5 kg and greater is based on clinical practice [ see Dosage and Administration ( 2.4 ) ].

🆘 Overdosage 128 words ▾

10 OVERDOSAGE An initial 150 mg/kg dose of acetylcysteine for a patient weighing 106 kg was mistakenly calculated as 160 g (a decimal point error resulting in a 10-fold higher than prescribed dose). An hour after infusion started, the patient complained of generalized heat sensation and body pain and developed widespread urticaria and hypotension. The second acetylcysteine infusion was withheld and the patient was treated for anaphylaxis.

Despite treatment the patient subcomed to the acute inflammatory reaction and died. Single intravenous doses of acetylcysteine at 1,000 mg/kg in mice, 2,445 mg/kg in rats, 1,500 mg/kg in guinea pigs, 1,200 mg/kg in rabbits and 500 mg/kg in dogs were lethal. Symptoms of acute toxicity in the animals were ataxia, hypoactivity, labored respiration, cyanosis, loss of righting reflex and convulsions.

🧬 Clinical Pharmacology ~1 min read ▾

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Acetylcysteine has been shown to reduce the extent of liver injury following acetaminophen overdose. Acetaminophen doses of 150 mg/kg or greater have been associated with hepatotoxicity. Acetylcysteine probably protects the liver by maintaining or restoring the glutathione levels, or by acting as an alternate substrate for conjugation with, and thus detoxification of, the reactive metabolite of acetaminophen.

12.3Pharmacokinetics After a single intravenous dose of acetylcysteine, the plasma concentration of total acetylcysteine declined in a poly-exponential decay manner with a mean terminal half-life (T 1/2 ) of 5.6 hours. The mean clearance (CL) for acetylcysteine was 0.11 liter/hr/kg and renal CL constituted about 30% of the total CL. Distribution The steady-state volume of distribution (Vd ss ) following administration of an intravenous dose of acetylcysteine was 0.47 liter/kg.

The protein binding of acetylcysteine ranges from 66% to 87%. Elimination Metabolism Acetylcysteine (i.e., N -acetylcysteine) is postulated to form cysteine and disulfides (N,N-diacetylcysteine and N -acetylcysteine). Cysteine is further metabolized to form glutathione and other metabolites.

Excretion After a single oral dose of [ 35 S]-acetylcysteine 100 mg, between 13% to 38% of the total radioactivity administered was recovered in urine within 24 hours. In a separate study, renal clearance was estimated to be approximately 30% of total body clearance. Specific Populations: Hepatic Impairment Following a 600 mg intravenous dose of acetylcysteine to subjects with mild (Child Pugh Class A, n=1), moderate (Child-Pugh Class B, n=4) or severe (Child-Pugh Class C; n=4) hepatic impairment and 6 healthy matched controls, mean T 1/2 increased by 80%.

Also, the mean CL decreased by 30% and the systemic acetylcysteine exposure (mean AUC) increased 1.6-fold in subjects with hepatic impairment compared to subjects with normal hepatic function. These changes are not considered to be clinically meaningful. Renal Impairment Hemodialysis may remove some of total acetylcysteine.

🧬 Mechanism of Action 61 words ▾

12.1Mechanism of Action Acetylcysteine has been shown to reduce the extent of liver injury following acetaminophen overdose. Acetaminophen doses of 150 mg/kg or greater have been associated with hepatotoxicity. Acetylcysteine probably protects the liver by maintaining or restoring the glutathione levels, or by acting as an alternate substrate for conjugation with, and thus detoxification of, the reactive metabolite of acetaminophen.

🧬 Pharmacokinetics ~1 min read ▾

12.3Pharmacokinetics After a single intravenous dose of acetylcysteine, the plasma concentration of total acetylcysteine declined in a poly-exponential decay manner with a mean terminal half-life (T 1/2 ) of 5.6 hours. The mean clearance (CL) for acetylcysteine was 0.11 liter/hr/kg and renal CL constituted about 30% of the total CL. Distribution The steady-state volume of distribution (Vd ss ) following administration of an intravenous dose of acetylcysteine was 0.47 liter/kg.

The protein binding of acetylcysteine ranges from 66% to 87%. Elimination Metabolism Acetylcysteine (i.e., N -acetylcysteine) is postulated to form cysteine and disulfides (N,N-diacetylcysteine and N -acetylcysteine). Cysteine is further metabolized to form glutathione and other metabolites.

Excretion After a single oral dose of [ 35 S]-acetylcysteine 100 mg, between 13% to 38% of the total radioactivity administered was recovered in urine within 24 hours. In a separate study, renal clearance was estimated to be approximately 30% of total body clearance. Specific Populations: Hepatic Impairment Following a 600 mg intravenous dose of acetylcysteine to subjects with mild (Child Pugh Class A, n=1), moderate (Child-Pugh Class B, n=4) or severe (Child-Pugh Class C; n=4) hepatic impairment and 6 healthy matched controls, mean T 1/2 increased by 80%.

Also, the mean CL decreased by 30% and the systemic acetylcysteine exposure (mean AUC) increased 1.6-fold in subjects with hepatic impairment compared to subjects with normal hepatic function. These changes are not considered to be clinically meaningful. Renal Impairment Hemodialysis may remove some of total acetylcysteine.

🔬 Clinical Studies ~2 min read ▾

14 CLINICAL STUDIES Loading Dose/Infusion Rate Study A randomized, open-label, multi-center clinical study was conducted in Australia in patients with acetaminophen poisoning to compare the rates of hypersensitivity reactions between two rates of infusion for the intravenous acetylcysteine loading dose. One hundred nine subjects were randomized to a 15-minute infusion rate and seventy-one subjects were randomized to a 60-minute infusion rate. The loading dose was 150 mg/kg followed by a maintenance dose of 50 mg/kg over 4 hours and then 100 mg/kg over 16 hours.

Of the 180 patients, 27% were male and 73% were female. Ages ranged from 15 to 83 years, with the mean age being 30 years (±13.0). A subgroup of 58 subjects (33 in the 15-minute infusion group; 25 in the 60-minute infusion group) was treated within 8 hours of acetaminophen ingestion.

No hepatotoxicity occurred within this subgroup; however, with 95% confidence, the true hepatotoxicity rates could range from 0% to 9% for the 15-minute infusion group and from 0% to 12% for the 60-minute infusion group. Observational Study An open-label, observational database contained information on 1,749 patients who sought treatment for acetaminophen overdose over a 16-year period. Of the 1,749 patients, 65% were female, 34% were male and less than 1% was transgender.

Ages ranged from 2 months to 96 years, with 72% of the patients falling in the 16- to 40-year-old age bracket. A total of 399 patients received acetylcysteine treatment. A post-hoc analysis identified 56 patients who (1) were at high or probable risk for hepatotoxicity (APAP greater than 150 mg/L at the four hours line according to the Australian nomogram) and (2) had a liver function test.

Of the 53 patients who were treated with intravenous acetylcysteine (300 mg/ kg intravenous acetylcysteine administered over 20 to 21 hours) within 8 hours, two (4%) developed hepatotoxicity (AST or ALT greater than 1,000 U/L). Twenty-one of 48 (44%) patients treated with acetylcysteine after 15 hours developed hepatotoxicity. The actual number of hepatotoxicity outcomes may be higher than what is reported here.

For patients with multiple admissions for acetaminophen overdose, only the first overdose treated with intravenous acetylcysteine was examined. Hepatotoxicity may have occurred in subsequent admissions. Evaluable data were available from a total of 148 pediatric patients (less than 16 years of age) who were admitted for poisoning following ingestion of acetaminophen, of whom 23 were treated with intravenous acetylcysteine.

There were no deaths of pediatric patients. None of the pediatric patients receiving intravenous acetylcysteine developed hepatotoxicity while two patients not receiving intravenous acetylcysteine developed hepatotoxicity. The number of pediatric patients is too small to provide a statistically significant finding of efficacy; however the results appear to be consistent to those observed for adults.

🧪 Nonclinical Toxicology 97 words ▾

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term studies in animals have not been performed to evaluate the carcinogenic potential of acetylcysteine. Acetylcysteine was not genotoxic in the Ames test or the in vivo mouse micronucleus test. It was, however, positive in the in vitro mouse lymphoma cell (L5178Y/TK +/- ) forward mutation test.

Treatment of male rats with acetylcysteine at an oral dose of 250 mg/kg/day for 15 weeks (0.1 times the recommended total human intravenous dose of 300 mg/kg based on body surface comparison) did not affect the fertility or general reproductive performance.

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

Medicare Part D (outpatient prescription) spending for Acetylcysteine — the program that covers self-administered drugs. 8 manufacturers.
⚠️ 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 Acetylcysteine. 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.
What does the discontinued status mean for this NDC?
The labeler reported a marketing end date (or the listing was delisted), so this specific package is no longer actively marketed. Remaining stock may still be dispensed for a time, and the NDC stays valid for historical records and claims — but data feeds (pricing, labeling) typically stop updating for it. Other package sizes or other manufacturers' versions of the same medication may still be marketed — see the equivalents section where available.
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 form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Who lists this product with the FDA?
Akorn 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 J0132 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.
For educational and professional reference only — not medical advice. Pricing reflects published NADAC and CMS ASP (free public data) and may differ from your acquisition cost; always verify before billing or dispensing.
