Quick answers
  • RxCUI (RxNorm): 2704833
Why two NDCs? The FDA registers this code as 85766-243-99 — a 5-3-2 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 product segment → 85766-0243-99. Same drug, same package — only the format differs.

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.

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.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through Dec 2040. This may affect when a full generic version becomes widely available, but it is not a guaranteed launch date.

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.

LOE
Substance patent Formulation patent Method-of-use patent Exclusivity Pediatric +6mo
🏛️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 this drug?
No FDA-approved generic equivalent is currently listed in the FDA Orange Book for this drug. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until Dec 2040 — 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.

⛔ Contraindications 34 words ▾

4 CONTRAINDICATIONS Concomitant use of JOURNAVX with strong CYP3A inhibitors is contraindicated [see Warnings and Precautions (5.1) , Drug Interactions (7.1) ] . Concomitant use with strong CYP3A inhibitors is contraindicated. ( 4 )

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS Moderate and Severe Hepatic Impairment : Avoid use in patients with severe hepatic impairment (Child-Pugh Class C). Use in patients with moderate hepatic impairment may increase the risk of adverse reactions. The recommended dosage is lower in patients with moderate hepatic impairment (Child-Pugh Class B) than those with normal hepatic function. ( 5.4 )

5.1Increased Risk of Adverse Reactions with Concomitant Use with Strong or Moderate CYP3A Inhibitors Strong and moderate CYP3A inhibitors increase suzetrigine and M6-SUZ (active metabolite) exposures which may cause JOURNAVX adverse reactions. Concomitant use of JOURNAVX with strong CYP3A inhibitors is contraindicated [see Drug Interactions (7.1) , Clinical Pharmacology (12.3) ] . Reduce the JOURNAVX dosage with moderate CYP3A inhibitors [see Dosage and Administration (2.3) ] .

5.2Risk of Drug Interactions with Certain CYP3A Substrates Suzetrigine is an inducer of CYP3A. If JOURNAVX is used concomitantly with sensitive CYP3A substrates or CYP3A substrates where minimal concentration changes may lead to loss of efficacy, refer to the Prescribing Information for the CYP3A substrates for dosing instructions. Dosage adjustment of the concomitant CYP3A substrates may be required when initiating or discontinuing JOURNAVX [see Drug Interactions (7.2) , Clinical Pharmacology (12.3) ].

5.3Risk of Drug Interactions with Certain Hormonal Contraceptives JOURNAVX-treated patients taking concomitant hormonal contraceptives containing progestins other than levonorgestrel and norethindrone should use additional nonhormonal contraceptives (such as condoms) or use alternative contraceptives (e.g., a combined oral contraceptive containing ethinyl estradiol as the estrogen and levonorgestrel or norethindrone as the progestin, an intrauterine system) during JOURNAVX treatment and for 28 days after discontinuation of JOURNAVX [see Drug Interactions (7.2) , Clinical Pharmacology (12.3) ].

5.4Risk of Adverse Reactions in Patients with Moderate and Severe Hepatic Impairment Patients with moderate hepatic impairment have higher systemic exposures of suzetrigine and M6-SUZ (active metabolite) than those with normal hepatic function which may increase the risk of JOURNAVX related adverse reactions [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] . Avoid use of JOURNAVX in patients with severe hepatic impairment (Child-Pugh Class C). The recommended JOURNAVX dosage is lower in patients with moderate hepatic impairment (Child-Pugh Class B) than those with normal hepatic function [see Dosage and Administration (2.2) ].

🤒 Adverse Reactions ~3 min read ▾

6 ADVERSE REACTIONS The most common adverse reactions (greater incidence in JOURNAVX-treated patients compared to placebo-treated patients) were pruritus, muscle spasms, increased creatine phosphokinase, and rash. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Vertex Pharmaceuticals Incorporated at 1-877-634-8789 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 practice. The safety profile of JOURNAVX is primarily based on data from the pooled, double-blind, placebo- and active-controlled trials in 874 adult patients with moderate to severe acute pain following full abdominoplasty (Trial 1) and bunionectomy (Trial 2) [see Clinical Studies (14) ] , with supportive safety data from one single arm trial in 256 adult patients with moderate to severe acute pain in a broad range of acute pain conditions (Trial 3).

In Trials 1 and 2, 874 patients received at least one dose of JOURNAVX. The proportion of patients in Trials 1 and 2 who discontinued study drug prematurely due to adverse events was: 0.6% in JOURNAVX-treated patients (postprocedural hematoma [0.2%], hypotension [0.2%], syncope [0.1%]), 0.6% in hydrocodone bitartrate/acetaminophen (HB/APAP)-treated patients (hypotension/orthostatic hypotension [0.2%], migraine [0.1%], intra-abdominal hematoma [0.1%], nausea [0.1%], pyrexia [0.1%]), and 0.2% in placebo-treated patients (hypotension [0.2%], tachycardia [0.2%]).

The safety profile of JOURNAVX was also evaluated by the following subgroup analyses: age (≥ 18 to < 65 years and ≥ 65 years), sex, and race. Since most patients enrolled in the clinical trials were ≥ 18 to < 65 years of age, female, and white, there was insufficient data to detect differences in safety signals between these subgroups. Table 2 displays adverse reactions that occurred more frequently in JOURNAVX-treated patients than placebo-treated patients in the pooled Trials 1 and 2.

Table 2: Adverse Reactions Reported in ≥1% of JOURNAVX-Treated Patients and Greater than Rate of Placebo in Two 48-hour Trials in Moderate to Severe Acute Pain (Trials 1 and 2, Pooled) Adverse Reactions (Preferred Term) Placebo (N = 438) n (%) JOURNAVX (N = 874) n (%) HB/APAP Patients received 5 mg/325 mg of oral hydrocodone bitartrate/acetaminophen (HB/APAP) every 6 hours.

In Trial 2, the incidence of patients who experienced either nausea or vomiting was 9% in JOURNAVX-treated patients, 16% in HB/APAP-treated patients, and 12% in placebo-treated patients. Laboratory Abnormalities Creatine Phosphokinase Elevations: In Trials 1 and 2, 2.9% of JOURNAVX-treated patients and 1.2% of placebo-treated patients had a creatine phosphokinase (CPK) level > 3 times the upper limit of normal. The incidence of increased blood CPK was 1.1% in JOURNAVX-treated patients and 0.5% in placebo-treated patients.

All reports of CPK elevations occurred in the post-surgical setting. There were no associated signs or symptoms, no serious adverse reactions, and no patients required treatment discontinuation or interruption. Decreased Estimated Glomerular Filtration Rate: In Trials 1 and 2, 2.5% of JOURNAVX-treated patients and 0.9% of placebo-treated patients had a decrease in estimated glomerular filtration rate (eGFR) of ≥ 25% but < 50%.

7 DRUG INTERACTIONS Strong and Moderate CYP3A inhibitors : Concomitant use with strong CYP3A inhibitors is contraindicated. Reduce the JOURNAVX dose when used concomitantly with moderate CYP3A inhibitors. Avoid food or drink containing grapefruit.

( 2.3 , 7.1 , 12.3 ) Strong and Moderate CYP3A inducers : Avoid JOURNAVX use with strong or moderate CYP3A inducers. ( 7.1 , 12.3 ) CYP3A substrates : If JOURNAVX is used concomitantly with sensitive CYP3A substrates or CYP3A substrates where minimal concentration changes may lead to loss of efficacy, refer to the Prescribing Information for the CYP3A substrates for dosing instructions. Dosage modification of the concomitant CYP3A substrates may be required when initiating or discontinuing JOURNAVX.

( 7.2 , 12.3 ) Hormonal contraceptives : JOURNAVX-treated patients using hormonal contraceptives containing progestins other than levonorgestrel and norethindrone should use an additional nonhormonal contraceptive method or an alternative hormonal contraceptive during concomitant use and for 28 days after JOURNAVX discontinuation. ( 7.2 )

7.1Effect of Other Drugs on JOURNAVX Table 3 describes drug interactions where concomitant use of another drug affects the use of JOURNAVX. Table 3: Drug Interactions: Concomitant Use of Other Drugs that Affect the Use of JOURNAVX Strong and Moderate Food or drink containing grapefruit should be avoided during treatment with JOURNAVX. CYP3A Inhibitors Prevention or Management Strong CYP3A inhibitors: Concomitant use of JOURNAVX with strong CYP3A inhibitors is contraindicated [see Warnings and Precautions (5.1) ] .

Moderate CYP3A inhibitors: Reduce the JOURNAVX dosage [see Dosage and Administration (2.3) , Warnings and Precautions (5.1) ] . Mechanism and Clinical Effect(s) Suzetrigine and M6-SUZ are CYP3A substrates. Strong and moderate CYP3A inhibitors increase suzetrigine and M6-SUZ (active metabolite of suzetrigine) exposures [see Clinical Pharmacology (12.3) ], which may cause JOURNAVX adverse reactions .

Strong and Moderate CYP3A Inducers Prevention or Management Avoid concomitant use of JOURNAVX with strong and moderate CYP3A inducers. Mechanism and Clinical Effect(s) Suzetrigine and M6-SUZ are CYP3A substrates. Concomitant use of strong or moderate CYP3A inducers results in reduced exposures of suzetrigine and M6-SUZ, which may result in reduced JOURNAVX efficacy [see Clinical Pharmacology (12.3) ] .

7.2Effect of JOURNAVX on Other Drugs CYP3A Substrates If JOURNAVX is used concomitantly with sensitive CYP3A substrates or CYP3A substrates where minimal concentration changes may lead to loss of efficacy, refer to the Prescribing Information for the CYP3A substrates for dosing instructions. Dosage modification of the concomitant CYP3A substrates may be required when initiating or discontinuing JOURNAVX [see Warnings and Precautions (5.2) ] . Suzetrigine is an inducer of CYP3A.

Concomitant use with JOURNAVX may reduce the exposure of sensitive CYP3A substrates which may decrease the efficacy of these substrates. Discontinuation of JOURNAVX may increase the exposure of sensitive CYP3A substrates [see Warnings and Precautions (5.2) , Clinical Pharmacology (12.3) ] . Hormonal Contraceptives JOURNAVX-treated patients using hormonal contraceptives containing progestins other than levonorgestrel and norethindrone should use additional nonhormonal contraceptives (such as condoms), or use alternative contraceptives (such as a combined oral contraceptive containing ethinyl estradiol as the estrogen and levonorgestrel or norethindrone as the progestin, or an intrauterine system) during treatment with JOURNAVX and for 28 days after discontinuation of JOURNAVX [see Warnings and Precautions (5.3) ] .

JOURNAVX did not result in clinically significant changes in the pharmacokinetics of ethinyl estradiol and levonorgestrel when used concomitantly with an oral contraceptive containing ethinyl estradiol and levonorgestrel [see Clinical Pharmacology (12.3) ] .

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary There are no available data on the use of JOURNAVX during pregnancy to evaluate for a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In animal reproduction studies in rats, effects on implantation and maintenance of pregnancy occurred at oral suzetrigine doses of ≥ 2.2-times the maximum recommended human dose (MRHD) when administered during early embryonic development or throughout organogenesis. In a pre- and postnatal development study, reduced mean gestation length and increased postnatal pup mortality were observed at maternal rat exposures of 1.6-times the MRHD and decreased rat pup body weights were observed during the period of birth to weaning at maternal exposures of 2.2-times the MRHD.

No malformations were observed when suzetrigine was administered orally to rats and rabbits during the period of organogenesis at doses up to 2.2- and 5.9-times, respectively, the MRHD. The clinical relevance of these findings is unclear. The background risk of major birth defects and miscarriage in patients with moderate to severe acute pain 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. Data Animal Data Suzetrigine was administered orally to pregnant rabbits during the period of organogenesis at 50, 100, and 200 mg/kg/day (approximately 1.6-, 3.1-, and 5.9-times, respectively, the steady state MRHD exposure based on AUC).

Increased post-implantation loss and lower fetal body weight were observed at 200 mg/kg/day, which is a dose that also caused maternal toxicity. No adverse embryofetal effects were observed at doses up to 100 mg/kg. Suzetrigine was administered orally to pregnant rats during the period of organogenesis at 5, 10, and 15 mg/kg/day (approximately 0.57-, 1.6-, and 2.2-times, respectively, the steady state MRHD exposure based on AUC).

Increased post-implantation loss and lower number of live fetuses were observed at 15 mg/kg/day. No adverse embryofetal effects were observed at doses up to 10 mg/kg. Placental transfer of suzetrigine was observed in pregnant rats.

In a pre- and postnatal development study, suzetrigine was administered orally to pregnant rats at doses of 5, 10, and 15 mg/kg/day (approximately 0.57-, 1.6-, and 2.2-times, respectively, the steady state MRHD exposure based on AUC) from Gestation Day 6 through Lactation Day 20. Reduced mean gestation length and increased postnatal pup mortality between birth and Postnatal Day 4 were observed at ≥ 10 mg/kg and increased incidences of fully resorbed litters, lower live newborn pups, and reductions in pup body weights were observed at 15 mg/kg.

No effects on learning and memory or sexual maturation were observed at dose up to 15 mg/kg/day. The effects on implantation, maintenance of pregnancy, reduced mean gestation length, and increased postnatal pup mortality in rats are of uncertain relevance to humans.

8.2Lactation Risk Summary There are no data on the presence of suzetrigine or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. Suzetrigine is present in animal milk. When a drug is present in animal milk, it is likely that the drug will be present in human milk.

The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for JOURNAVX and any potential adverse effects on the breastfed child from JOURNAVX or from the underlying maternal condition.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Suzetrigine is a selective blocker of the Na V 1.8 voltage-gated sodium channel, compared to other known voltage-gated sodium channels (Na V 1.1 through 1.9). Na V 1.8 is expressed in peripheral sensory neurons including dorsal root ganglion neurons, where its role is to transmit pain signals (action potentials). By selectively inhibiting Na V 1.8 channels, suzetrigine inhibits transmission of pain signals to the spinal cord and brain.

M6-SUZ, a major active metabolite, is a less potent inhibitor of Na V 1.8 than suzetrigine by 3.7-fold.

12.2Pharmacodynamics Cardiac Electrophysiology At 2 times the exposure of the maximum recommended JOURNAVX dose, clinically significant QTc prolongation was not observed.

The median T max of suzetrigine and M6-SUZ in the fasted state was 3 hours and 8 to 10 hours, respectively. When administered in the fed state (high-fat meal or moderate-fat meal) the median T max of suzetrigine was delayed to 5 hours and the median T max of M6-SUZ was delayed to 24 hours. The C max and AUC of suzetrigine and M6-SUZ were not affected by any of the meal conditions, including a high-fat meal consumed one hour after JOURNAVX administration.

Administration of the second JOURNAVX dose of 50 mg with or without regard to meals is predicted to not affect the systemic exposures of suzetrigine and M6-SUZ. Specific Populations No clinically significant differences in pharmacokinetics of suzetrigine and M6-SUZ were observed based on age (18-75 years), sex, body weight (44-126 kg), race, and renal impairment (eGFR ≥ 15 mL/min by CKD-EPI equation with adjustment for the body surface area). The effect of renal impairment with eGFR < 15 mL/min on suzetrigine and M6-SUZ pharmacokinetics is unknown.

Patients with Hepatic Impairment In patients with mild hepatic impairment (Child-Pugh Class A), no clinically significant differences in pharmacokinetics of suzetrigine and M6-SUZ were observed. In patients with moderate hepatic impairment (Child-Pugh Class B), at steady state, suzetrigine AUC 0-12h increased by 1.5-fold (90% CI: 1.1-2.1) and C max increased by 1.3-fold (90% CI: 1.0-1.7) and M6-SUZ AUC 0-1… [Excerpted — this section continues on DailyMed.]

14 CLINICAL STUDIES

14.1Overview of Clinical Studies The efficacy of JOURNAVX in the treatment of moderate to severe acute pain in adults was established in two randomized, double-blind, placebo and active-controlled trials of acute pain, one following full abdominoplasty (Trial 1) [see Clinical Studies (14.2) ] and the other following bunionectomy (Trial 2) [see Clinical Studies (14.3) ] . In each trial, pain intensity was measured using a patient-reported 11-point numeric pain rating scale (NPRS), ranging from 0 to 10, where zero corresponds to no pain and 10 corresponds to the worst pain imaginable.

Patients were eligible for study participation if they had moderate to severe pain on the verbal categorical rating system (VRS) and a pain score of ≥ 4 on the NPRS, within 4 hours of the abdominoplasty completion (Trial 1) or during the 9-hour period after discontinuation of regional anesthesia following bunionectomy (Trial 2). Once eligible, patients were randomized to receive oral JOURNAVX, placebo, or hydrocodone bitartrate/acetaminophen (HB/APAP) for a duration of 48 hours. For the JOURNAVX treatment regimen, patients received an initial loading dose of 100 mg JOURNAVX, followed by 50 mg every 12 hours.

For the HB/APAP-control regimen, patients received 5 mg/325 mg every 6 hours. For both studies, 400 mg of ibuprofen every 6 hours, as needed for pain relief, was permitted as a rescue medication.

14.2Moderate to Severe Acute Pain Following Full Abdominoplasty Trial 1 [NCT05558410] evaluated the efficacy of JOURNAVX over 48 hours in 1,118 adult patients with moderate to severe acute pain following a full abdominoplasty procedure (JOURNAVX n = 447, placebo n = 223, and hydrocodone bitartrate/acetaminophen (HB/APAP) n = 448). The majority of patients were female (98%), and the mean age was 42 years (range: 18 to 69). The study population consisted of 70% White participants, 27% Black or African American participants, 1% Asian participants, 0.8% Native Hawaiian or other Pacific Islander participants, 0.5% American Indian or Alaska Native participants, and 0.9% Other or Multiracial participants, among which 34% identified as Hispanic or Latino.

The mean pain score at baseline was 7.4 (range: 4 to 10). All baseline characteristics, including NPRS, VRS, and BMI were generally balanced across treatment arms. In Trial 1, 89% of patients in the JOURNAVX group completed the treatment period (compared to 75% of patients in the placebo group and 85% of patients in the HB/APAP group), and 9% of patients in the JOURNAVX group discontinued due to lack of efficacy (compared to 22% of patients in the placebo group and 13% of patients in the HB/APAP group).

Efficacy was evaluated by the time-weighted sum of the pain intensity difference from 0 to 48 hours (SPID48) in the JOURNAVX group compared to the placebo group and then to the HB/APAP group. Treatment with JOURNAVX demonstrated statistically significant superior reduction in pain compared to treatment with placebo (see Table 5 ). In an exploratory analysis, the time-weighted sum of the pain intensity difference from 0 to 24 hours (SPID24) reported using the least square mean was 48.0 for the JOURNAVX group and 24.2 for the placebo group.

The mean pain intensities over time are depicted for the JOURNAVX, placebo, and HB/APAP groups in Figure 1.

Mutagenesis Suzetrigine was not mutagenic in the bacterial reverse mutation assay (Ames test), or clastogenic in the in vitro micronucleus assay with a human TK6 lymphoblastoid cell line, or in the in vivo rat bone marrow micronucleus assay. Impairment of Fertility In a female fertility study, female rats were treated orally with suzetrigine at 5, 10, and 15 mg/kg/day for a minimum of 14 days prior to mating, throughout mating, and through Gestation Day 7.

These doses are approximately 0.57, 1.6, and 2.2-times the steady state MRHD exposure based on AUC. Increased pre-implantation loss was observed at 15 mg/kg (approximately 2.2-times the MRHD based on AUC). The finding in rats may be explained by the effect of suzetrigine on the rat progesterone receptor, which was more sensitive to suzetrigine than the human progesterone receptor based on in vitro studies.

Following 4-week withdrawal of treatment, there were no effects on female fertility and early embryonic development. The finding in the rat study is of uncertain relevance to humans. In a male fertility study, male rats were treated orally with suzetrigine at 200, 600, and 1000 mg/kg/day for a minimum of 28 days prior to mating and through mating.

These doses are 3.6, 9.7, and 13.8-times the steady state MRHD exposure based on AUC, respectively. Suzetrigine had no effects on sperm parameters (motility, concentration, or morphology), reproductive performance or uterine parameters (number of implants, viable implants, pre-implantation loss, early resorptions, and post-implantation loss) at any dose.

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

Medicare Part D (outpatient prescription) spending for Journavx — 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 Journavx. 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.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

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 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.
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 Sportpharm LLC. 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 3 other package presentations of this same product, including 20 tablets (85766-0243-20), 30 tablets (85766-0243-30), 100 tablets (85766-0243-01). 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?
Sportpharm 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.
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.
