Why two NDCs? The FDA registers this code as 0469-2660-90 — a 4-4-2 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 labeler segment → 00469-2660-90. Same drug, same package — only the format differs.

10 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?

Data sourced from official FDA Structured Product Labeling (SPL) via DailyMed — ingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

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 system	Per each	Per package
Retail pharmacies payNADAC · weekly	Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo	No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · Q2 2026	$19.63	$1,766.89 / 90 tablets

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.

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

🏛️FDA exclusivity

FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.

🧪Product / substance patents

Patents covering the active ingredient, product, formulation, or related drug features.

🎯Method-of-use patents

Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.

🛈 What do these terms mean?

Patent: Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent: Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent: Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent: A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label: A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity: FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV: A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS: Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating: FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity): The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions

Is there a generic version of VEOZAH 45 MG TABLET?

No FDA-approved generic equivalent is currently listed in the FDA Orange Book for VEOZAH 45 MG TABLET. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until Mar 2034 — an estimate, not a guaranteed launch date.

The FDA approved a generic — why can’t I get it at my pharmacy yet?

FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.

Why do different websites show different generic release dates?

Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.

What does “FDA listed” mean?

It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.

What does a patent or protection date mean here?

It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).

What does “current Orange Book estimate” mean?

It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.

Can a generic come out before the last patent expires?

Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.

Can a generic come out after the listed dates?

Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.

What is the difference between patents and exclusivity?

Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.

Why are there multiple patent dates?

One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.

Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.

Where does this data come from?

Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

💊 Medicaid utilization by pack size

Medicaid (SDUD) totals over the four most recent reported quarters for every package size of this drug — handy when a specific package (e.g. a starter/titration pack) carries little or no Medicaid volume on its own.

⚠️ 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 Veozah. 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.

Pack size FAQ

What quantity is in NDC 00469-2660-90?

NDC 00469-2660-90 is a 90-count package — 1 bottle in 1 carton / 90 tablet, film coated in 1 bottle.

What is the difference between NDC 00469-2660-90 and NDC 00469-2660-30?

Both are VEOZAH fezolinetant 45 mg Tablet, Film Coated — the drug itself is identical. NDC 00469-2660-90 is the 90-count package, while NDC 00469-2660-30 is the 30 tablets package.

What NDC number is used to bill for this package of VEOZAH fezolinetant 45 mg Tablet, Film Coated?

Bill NDC 00469-2660-90 — the 11-digit billing format is 00469266090. Pharmacy and medical claims use the 11-digit form; the FDA label may print a shorter form of the same code.

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 0469-2660-90, 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: 00469-2660-90, written without dashes as 00469266090. 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 00469-2660-90, the first segment (00469) is the labeler code FDA assigned to Astellas Pharma US, Inc.; the middle segment (2660) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (90) 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 Astellas Pharma US, Inc.. Listing status can change — the directory data on this page refreshes weekly.

Does this product come in other package sizes?

Yes — the FDA directory lists 1 other package presentation of this same product, including 30 tablets (00469-2660-30). Each has its own NDC and its own page — see the package list near the top of this page.

Who lists this product with the FDA?

Astellas Pharma US, Inc. 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.

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 Hepatotoxicity: Cases of hepatotoxicity and jaundice have been reported in the postmarketing setting. Perform hepatic laboratory tests prior to initiation of VEOZAH to evaluate for hepatic function and injury. Perform follow-up hepatic laboratory tests monthly for the first 3 months, at 6 months, and 9 months after initiation of therapy.

5.1Hepatotoxicity In three clinical trials, elevations in serum transaminase [alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST)] levels > 3 x the upper limit of normal (ULN) occurred in 2.3% [exposure adjusted incidence rate (EAIR) of 2.7 per 100 person-years] of women receiving VEOZAH and 0.9% (EAIR of 1.5 per 100 person-years) of women receiving placebo. No elevations in serum total bilirubin (> 2 x ULN) occurred. Women with ALT or AST elevations were generally asymptomatic.

Transaminase levels returned to pretreatment levels (or close to these) without sequelae with dose continuation, and upon dose interruption, or discontinuation. Women with cirrhosis were not studied [see Adverse Reactions ( 6.1 )] . In the postmarketing setting, cases of drug-induced liver injury with elevations of ALT, AST, alkaline phosphatase (ALP), and total bilirubin occurred within 40 days of starting VEOZAH.

Patients reported a general sense of feeling unwell and symptoms of fatigue, nausea, pruritus, jaundice, pale feces, and dark urine. The patients’ signs and symptoms gradually resolved after discontinuation of VEOZAH [see Adverse Reactions ( 6.2 )]. Perform baseline hepatic laboratory tests to evaluate for hepatic function and injury [including serum ALT, serum AST, serum ALP, and serum bilirubin (total and direct)] prior to VEOZAH initiation.

Do not start VEOZAH if ALT or AST is ≥ 2 x ULN or if the total bilirubin is ≥ 2 x ULN for the evaluating laboratory. Perform follow-up hepatic laboratory tests monthly for the first 3 months, at 6 months, and 9 months after initiation of therapy. Advise patients to discontinue VEOZAH immediately and seek medical attention including hepatic laboratory tests if they experience signs or symptoms that may suggest liver injury: • new onset fatigue, decreased appetite, nausea, vomiting, pruritus, jaundice, pale feces, dark urine, or abdominal pain.

Discontinue VEOZAH if: • transaminase elevations are > 5 x ULN. • transaminase elevations are > 3 x ULN and total bilirubin is > 2 x ULN. If transaminase elevations > 3 x ULN occur, perform more frequent follow-up hepatic laboratory tests until resolution. Exclude alternative causes of hepatic laboratory test elevations.

6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: • Hepatic Transaminase Elevation and Hepatotoxicity [see Warnings and Precautions ( 5.1 )] . The most common adverse reactions with VEOZAH [at least 2% in VEOZAH 45 mg and greater than placebo] are: abdominal pain, diarrhea, insomnia, back pain, hot flush, and hepatic transaminase elevation. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Astellas Pharma US, Inc. at 1-800-727-7003 or FDA at 1-800-FDA-1088 or 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 clinical practice. The safety of VEOZAH was evaluated in three 52-week clinical trials [see Clinical Studies ( 14 )] . Across the three clinical trials, a total of 1100 women received VEOZAH.

Trials 1 and 2 were placebo-controlled for the first 12 weeks, followed by re-randomization of women previously receiving placebo to VEOZAH (women on VEOZAH remained on VEOZAH) for an additional 40 weeks of uncontrolled treatment. Trial 3 was a randomized, placebo-controlled, double-blind safety study evaluating the safety of VEOZAH for 52 weeks. The adverse reactions reported in at least 2% in VEOZAH 45 mg and greater than placebo in Trial 3 are presented in Table 1 .

Table 1: Adverse Reactions Reported in at Least 2% in VEOZAH 45 mg and Greater Than Placebo in a Placebo‑Controlled, Double-Blind 52-Week Trial (Trial 3) Adverse Reaction VEOZAH 45 mg (n=609) Total Person-Years=504.2 n (%, EAIR EAIR = Number of individuals experiencing an adverse event divided by exposure time (total person-years) x 100. ) Placebo (n=610) Total Person-Years=475.0 n (%, EAIR ) Abdominal pain Abdominal pain (including Abdominal pain, Abdominal pain lower, Abdominal pain upper). 26 (4.3%, 5.2) 13 (2.1%, 2.7) Diarrhea 24 (3.9%, 4.8) 16 (2.6%, 3.4) Insomnia 24 (3.9%, 4.8) 11 (1.8%, 2.3) Back pain 18 (3.0%, 3.6) 13 (2.1%, 2.7) Hot flush 15 (2.5%, 3.0) 10 (1.6%, 2.1) Hepatic transaminase elevation Hepatic transaminase elevations (including Alanine aminotransferase abnormal, Alanine aminotransferase increased, Aspartate aminotransferase abnormal, Aspartate aminotransferase increased).

14 (2.3%, 2.8) 5 (0.8%, 1.1) In the pooled laboratory data of Trials 1, 2, and 3, elevated hepatic transaminases (> 3 x ULN) occurred in 25 women (2.3%,

2.7EAIR) exposed to VEOZAH 45 mg (n=1100, 912.1 total person-years) as compared to 8 women (0.9%,

1.5EAIR) exposed to placebo (n=952, 549.1 total person-years).

6.2Postmarketing Experience The following adverse reactions have been identified during postapproval use of VEOZAH. Because these 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. Hepatic : Cases of serious drug-induced hepatotoxicity occurred within 40 days of starting VEOZAH.

Patients experienced elevated transaminases (up to 50 x ULN at peak elevation), elevated alkaline phosphatase (up to 4 x ULN at peak elevation), and bilirubin (up to 5 x ULN at peak elevation) coupled with symptoms of fatigue, nausea, pruritus, jaundice, pale feces, and dark urine. After discontinuation of VEOZAH, these abnormalities gradually resolved.

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary There are no data on VEOZAH use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In embryo-fetal toxicity animal studies with fezolinetant, embryo-lethality occurred at high doses above the human therapeutic dose in rats and rabbits, but no teratogenicity was observed. In the pre- and post-natal development animal study, delayed parturition and embryo-lethality occurred at high doses above the human therapeutic dose in rats.

Additionally, in the male offspring delayed male reproductive maturation was observed, characterized by incomplete preputial separation, which affected male fertility at doses above the human therapeutic dose in rats [see Data ] . In the U.S. general population, the estimated background risk of major birth defects or miscarriage in clinically recognized pregnancies are 2-4% and 15-20%, respectively. Data Animal Data In embryo-fetal development toxicity studies in rats and rabbits, embryo-lethality was noted at the highest doses (128- and 174-fold the human AUC 24 at the human therapeutic dose for rats and rabbits, respectively).

The no observed adverse effect level (NOAEL) for embryo-fetal development was 50 mg/kg/day in rats and 45 mg/kg/day in rabbits (62- and 16‑fold the human AUC 24 at the human therapeutic dose for rats and rabbits, respectively). Fezolinetant showed no effects on fertility and early embryonic development in rats [see Nonclinical Toxicology ( 13.1 )] . In the pre- and post-natal development study in rats, the NOAEL for maternal and fetal toxicity was 30 mg/kg/day (36‑fold the human AUC 24 at the human therapeutic dose) based on delayed parturition and embryo-lethality at 100 mg/kg/day.

The NOAEL for F 1 generation development was determined to be 100 mg/kg/day for females (204-fold the human AUC 24 at the human therapeutic dose) and 10 mg/kg/day for males (11-fold the human AUC 24 at the human therapeutic dose). The F 1 male showed delayed male reproductive maturation, characterized as incomplete balanopreputial separation at time of mating, at doses of greater than or equal to 30 mg/kg/day (36-fold the human AUC 24 at the human therapeutic dose), which affected male fertility [see Nonclinical Toxicology ( 13.1 )] .

8.2Lactation Risk Summary There are no data on the presence of fezolinetant in human milk, the effects on the breastfed child, or the effects on milk production. It is not known if fezolinetant is present in human milk. Data Animal Data Following administration of radiolabeled fezolinetant to lactating rats, the radioactivity concentration in milk was higher than that in the plasma at all time points, indicating that fezolinetant-derived components transferred to the tissues in infant rats via breast milk.

8.4Pediatric Use The efficacy and safety of VEOZAH in individuals less than 18 years of age have not been established.

8.5Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical trials utilizing VEOZAH to determine whether those over 65 years of age differ from younger women in their response to VEOZAH.

8.6Renal Impairment VEOZAH is contraindicated in individuals with severe (eGFR 15 to less than 30 mL/min/1.73 m 2 ) renal impairment or end-stage renal disease (eGFR less than 15 mL/min/1.73 m 2 ) [see Clinical Pharmacology ( 12.3 )] . No dose adjustment of VEOZAH is recommended for individuals with mild (eGFR 60 to less than 90 mL/min/1.73 m 2 ) or moderate (eGFR 30 to less than 60 mL/min/1.73 m 2 ) renal impairment.

8.7Hepatic Impairment Child-Pugh Class A or B hepatic impairment increased the exposure of VEOZAH [see Clinical Pharmacology ( 12.3 )] . VEOZAH has not been studied in individuals with Child-Pugh Class C hepatic impairment. VEOZAH is contraindicated in individuals with cirrhosis [see Clinical Pharmacology ( 12.3 )] .

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action VEOZAH is a neurokinin 3 (NK3) receptor antagonist that blocks neurokinin B (NKB) binding on the kisspeptin/neurokinin B/dynorphin (KNDy) neuron to modulate neuronal activity in the thermoregulatory center. Fezolinetant has high affinity for the NK3 receptor (Ki value of 19.9 to 22.1 nmol/L), which is more than 450-fold higher than binding affinity to NK1 or NK2 receptors.

12.2Pharmacodynamics Treatment with fezolinetant did not show any clear trends in sex hormones measured (follicle-stimulating hormone, testosterone, estrogen, and dehydroepiandrosterone sulfate) in menopausal women. Transient decrease of luteinizing hormone (LH) levels was observed at peak concentrations of fezolinetant. Cardiac Electrophysiology At a dose 20 times the maximum approved recommended dose, fezolinetant does not prolong the QT interval to any clinically relevant extent.

12.3Pharmacokinetics In healthy women, fezolinetant C max and AUC increased proportionally over a dosage range from 20 to 60 mg once daily (0.44 to 1.33 times the approved recommended dosage). Steady-state plasma concentrations of fezolinetant were reached after two once daily doses, with minimal fezolinetant accumulation. Absorption The median (range) time to reach fezolinetant C max is 1.5 (1 to 4) hours in healthy women.

Effect of Food No clinically significant differences in fezolinetant pharmacokinetics were observed following administration with a high‑calorie, high-fat meal containing approximately 1000 calories (500-600 calories from fat, 250 calories from carbohydrates, and 150 calories from protein). Distribution The mean apparent volume of distribution (V z /F) of fezolinetant is 189 L. The plasma protein binding of fezolinetant is 51%.

The blood-to-plasma ratio is 0.9. Elimination The effective half-life (t 1/2 ) of fezolinetant is 9.6 hours in women with vasomotor symptoms. The apparent clearance at steady-state of fezolinetant is

10.8L/h. Metabolism Fezolinetant is primarily metabolized by CYP1A2 and to a lesser extent by CYP2C9 and CYP2C19. A major metabolite of fezolinetant, ES259564, was identified in plasma.

ES259564 is approximately 20-fold less potent than the parent. The metabolite-to-parent ratio ranges from 0.7 to 1.8. Excretion Following oral administration of fezolinetant, 76.9% of the dose was excreted in urine (1.1% unchanged) and 14.7% in feces (0.1% unchanged).

Specific Populations There were no substantive differences in the pharmacokinetics of VEOZAH based on race and body weight (93 to 278 pounds). Women with Renal Impairment Following single-dose administration of 30 mg fezolinetant, there was no effect on VEOZAH exposure (C max and AUC) in women with mild (eGFR 60 to less than 90 mL/min/1.73 m 2 ) to severe (eGFR 15 to less than 30 mL/min/1.73 m 2 ) renal impairment. The AUC of ES259564 (a major metabolite of fezolinetant) in women with moderate (eGFR 30 to less than 60 mL/min/1.73 m 2 ) and severe (eGFR 15 to less than 30 mL/min/1.73 m 2 ) renal impairment increased by approximately 75% and 380%, respectively.

VEOZAH has not been studied in individuals with end-stage renal disease (eGFR less than 15 mL/min/1.73 m 2 ). Women with Hepatic Impairment Following single-dose administration of 30 mg fezolinetant in women with mild Child-Pugh Class A cirrhosis, the mean C max increased by 23% and AUC inf increased by 56%, relative to women with normal hepatic function. In women with moderate Child-Pugh Class B cirrhosis, the mean C max of fezolinetant decreased by 15% and AUC inf increased by 96%.

The C max of ES259564 decreased in both mild and moderate cirrhosis while AUC inf and AUC last increased less than 15%. VEOZAH has not been studied in individuals with severe Child-Pugh Class C cirrhosis.
