Why two NDCs? The FDA registers this code as 81968-350-01 — 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 → 81968-0350-01. Same drug, same package — only the format differs.

📖 What it is MedlinePlus · NLM

Solriamfetol is used to treat excessive daytime sleepiness caused by narcolepsy (a condition that causes excessive daytime sleepiness). Solriamfetol is also used along with breathing devices or other treatments to prevent excessive daytime sleepiness caused by obstructive sleep apnea/hypopnea syndrome (OSAHS; a sleep disorder in which the patient briefly stops breathing or breathes shallowly many times during sleep and therefore doesn't get enough restful sleep). Solriamfetol is in a class of medications called wakefulness promoting agents. It works by increasing the amounts of certain natural...

  • 0.23 mg UNII EX438O2MRT
    Ferric oxide yellow is a naturally occurring iron compound used as a colorant in medications. It gives tablets, capsules, and other forms a yellow or golden hue for identification and appearance.
  • 2.75 mg UNII UKE75GEA7F
    Hydroxypropyl cellulose is a plant-based polymer used as a binder and thickener. It helps hold tablet ingredients together, controls how fast the medicine dissolves, and improves the texture of liquid formulations.
  • 0.5 mg UNII 70097M6I30
    Magnesium stearate is a salt made from magnesium and stearic acid, a fatty substance. It's used in tablets and capsules as a lubricant and glidant to help ingredients flow smoothly during manufacturing and prevent sticking.
  • 0.65 mg UNII G2M7P15E5P
    Polyethylene glycol 3350 is a synthetic polymer used as a solvent, humectant, and thickening agent in medicines. It helps dissolve other ingredients, retain moisture in the product, and achieve the desired consistency.
  • 1.3 mg UNII 532B59J990

7 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.

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.

🔒Generic approved by FDA, but pharmacy availability is not confirmed

The FDA lists approved generic versions of this medicine, but that does not always mean a pharmacy can get one today. Patent rules, launch agreements, supply and pricing can affect when generics actually arrive.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through Dec 2042. This may affect when a full generic version becomes widely available, but it is not a guaranteed launch date.
📅 FDA approved Jun 17, 2019 AB TE-rated RLD RS ⏳ ~16.3 yr to latest listed protection

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 SUNOSI 75 MG TABLET?
Yes — an FDA-approved generic equivalent is listed in the FDA Orange Book for SUNOSI 75 MG TABLET. See the alternatives section for substitutable, lower-cost products.
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 & 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 81968-0350-01, 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 – Q1 2026 · 5 quarters of data
ⓘ The newest quarter is usually incomplete when first published; states restate recent quarters in later CMS releases, so the latest figures typically revise upward. State coverage-policy changes can also shift quarter-to-quarter totals.

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

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

1 INDICATIONS AND USAGE SUNOSI is indicated to improve wakefulness in adult patients with excessive daytime sleepiness associated with narcolepsy or obstructive sleep apnea (OSA) [see Clinical Studies ( 14 )] . Limitations of Use SUNOSI is not indicated to treat the underlying airway obstruction in OSA. Ensure that the underlying airway obstruction is treated (e.g., with continuous positive airway pressure (CPAP)) for at least one month prior to initiating SUNOSI for excessive daytime sleepiness.

Modalities to treat the underlying airway obstruction should be continued during treatment with SUNOSI. SUNOSI is not a substitute for these modalities. SUNOSI is a dopamine and norepinephrine reuptake inhibitor (DNRI) indicated to improve wakefulness in adult patients with excessive daytime sleepiness associated with narcolepsy or obstructive sleep apnea (OSA).

Concurrent treatment with a monoamine oxidase inhibitor (MAOI) or use of an MAOI within the preceding 14 days. ( 4 )

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS Blood Pressure and Heart Rate Increases : Measure heart rate and blood pressure prior to initiating and periodically throughout treatment. Control hypertension before and during therapy. Avoid use in patients with unstable cardiovascular disease, serious heart arrhythmias, or other serious heart problems.

( 5.1 ) Psychiatric Symptoms : Use caution in treating patients with a history of psychosis or bipolar disorders. Consider dose reduction or discontinuation of SUNOSI if psychiatric symptoms develop. ( 5.2 )

5.1Blood Pressure and Heart Rate Increases SUNOSI increases systolic blood pressure, diastolic blood pressure, and heart rate in a dose-dependent fashion [see Adverse Reactions ( 6.1 )] . Epidemiological data show that chronic elevations in blood pressure increase the risk of major adverse cardiovascular events (MACE), including stroke, heart attack, and cardiovascular death. The magnitude of the increase in absolute risk is dependent on the increase in blood pressure and the underlying risk of MACE in the population being treated.

Many patients with narcolepsy and OSA have multiple risk factors for MACE, including hypertension, diabetes, hyperlipidemia, and high body mass index (BMI). Assess blood pressure and control hypertension before initiating treatment with SUNOSI. Monitor blood pressure regularly during treatment and treat new-onset hypertension and exacerbations of pre-existing hypertension.

Exercise caution when treating patients at higher risk of MACE, particularly patients with known cardiovascular and cerebrovascular disease, pre-existing hypertension, and patients with advanced age. Use caution with other drugs that increase blood pressure and heart rate [see Drug Interactions ( 7.2 )] . Periodically reassess the need for continued treatment with SUNOSI.

If a patient experiences increases in blood pressure or heart rate that cannot be managed with dose reduction of SUNOSI or other appropriate medical intervention, consider discontinuation of SUNOSI. Patients with moderate or severe renal impairment may be at a higher risk of increases in blood pressure and heart rate because of the prolonged half-life of SUNOSI [see Dosage and Administration ( 2.5 ), Clinical Pharmacology ( 12.3 )] .

5.2Psychiatric Symptoms Psychiatric adverse reactions have been observed in clinical trials with SUNOSI, including anxiety, insomnia, and irritability [see Adverse Reactions ( 6.1 )] . SUNOSI has not been evaluated in patients with psychosis or bipolar disorders. Exercise caution when treating patients with SUNOSI who have a history of psychosis or bipolar disorders.

Patients with moderate or severe renal impairment may be at a higher risk of psychiatric symptoms because of the prolonged half-life of SUNOSI [see Dosage and Administration ( 2.5 ), Clinical Pharmacology ( 12.3 )] . Patients treated with SUNOSI should be observed for the possible emergence or exacerbation of psychiatric symptoms. If psychiatric symptoms develop in association with the administration of SUNOSI, consider dose reduction or discontinuation of SUNOSI.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in 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 of SUNOSI has been evaluated in 930 patients (ages 18 to 75 years) with narcolepsy or OSA. Among these patients, 396 were treated with SUNOSI in the 12-week placebo-controlled trials at doses of 37.5 mg (OSA only), 75 mg, and 150 mg once daily.

Information provided below is based on the pooled 12-week placebo-controlled studies in patients with narcolepsy or OSA. Most Common Adverse Reactions The most common adverse reactions (incidence ≥ 5% and greater than placebo) reported more frequently with the use of SUNOSI than placebo in either the narcolepsy or OSA populations were headache, nausea, decreased appetite, anxiety, and insomnia. Table 1 presents the adverse reactions that occurred at a rate of ≥ 2% and more frequently in SUNOSI-treated patients than in placebo-treated patients in the narcolepsy population.

7 DRUG INTERACTIONS Drugs that Increase Blood Pressure and/or Heart Rate and Dopaminergic Drugs : Use caution when co-administering with SUNOSI. ( 7.2 , 7.3 )

7.1Monoamine Oxidase (MAO) Inhibitors Do not administer SUNOSI concomitantly with MAOIs or within 14 days after discontinuing MAOI treatment. Concomitant use of MAO inhibitors and noradrenergic drugs may increase the risk of a hypertensive reaction. Potential outcomes include death, stroke, myocardial infarction, aortic dissection, ophthalmological complications, eclampsia, pulmonary edema, and renal failure [see Contraindications ( 4 )].

7.2Drugs that Increase Blood Pressure and/or Heart Rate Concomitant use of SUNOSI with other drugs that increase blood pressure and/or heart rate has not been evaluated, and such combinations should be used with caution [see Warnings and Precautions ( 5.1 )].

7.3Dopaminergic Drugs Dopaminergic drugs that increase levels of dopamine or that bind directly to dopamine receptors might result in pharmacodynamic interactions with SUNOSI. Interactions with dopaminergic drugs have not been evaluated with SUNOSI. Use caution when concomitantly administering dopaminergic drugs with SUNOSI.

Healthcare providers are encouraged to register pregnant patients, or pregnant women may enroll themselves in the registry by calling 1-877-283-6220 or contacting the company at www.SunosiPregnancyRegistry.com . Risk Summary Available data from case reports are not sufficient to determine drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes.

In animal reproductive studies, oral administration of solriamfetol during organogenesis caused maternal and fetal toxicities in rats and rabbits at doses ≥ 4 and 5 times and was teratogenic at doses 19 and ≥ 5 times, respectively, the maximum recommended human dose (MRHD) of 150 mg based on mg/m 2 body surface area. Oral administration of solriamfetol to pregnant rats during pregnancy and lactation at doses ≥ 7 times the MRHD based on mg/m 2 body surface area resulted in maternal toxicity and adverse effects on fertility, growth, and development in offspring (see Data ).

The estimated background risk of major birth defects and miscarriage for 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 risks of major birth defects and miscarriage in clinically recognized pregnancies are 2% to 4% and 15% to 20%, respectively.

Data Animal Data Solriamfetol was administered orally to pregnant rats during the period of organogenesis at 15, 67, and 295 mg/kg/day, which are approximately 1, 4, and 19 times the MRHD based on mg/m 2 body surface area. Solriamfetol at ≥ 4 times the MRHD caused maternal toxicity that included hyperactivity, significant decreases in body weight, weight gain, and food consumption. Fetal toxicity at these maternally toxic doses included increased incidence of early resorption and post-implantation loss, and decreased fetal weight.

Solriamfetol was teratogenic at 19 times the MRHD; it increased the incidence of fetal malformations that included severe sternebrae mal-alignment, hindlimb rotation, bent limb bones, and situs inversus. This dose was also maternally toxic. The no-adverse-effect level for malformation is 4 times and for maternal and embryofetal toxicity is approximately 1 times the MRHD based on mg/m 2 body surface area.

Solriamfetol was administered orally to pregnant rabbits during the period of organogenesis at 17, 38, and 76 mg/kg/day, which are approximately 2, 5, and 10 times the MRHD based on mg/m 2 body surface area. Solriamfetol at 10 times the MRHD caused maternal toxicity of body weight loss and decreased food consumption. Solriamfetol was teratogenic at ≥ 5 times the MRHD, it caused fetal skeletal malformation (slight-to-moderate sternebrae mal-alignment) and decreased fetal weight.

The no-adverse-effect level for malformation and fetal toxicity is approximately 2 times and for maternal toxicity is approximately 5 times the MRHD based on mg/m 2 body surface area. Solriamfetol was administered orally to pregnant rats during the period of organogenesis from gestation day 7 through lactation day 20 post-partum, at 35, 110, and 350 mg/kg/day, which are approximately 2, 7, and 22 times the MRHD based on mg/m 2 body surface area. At ≥ 7 times the MRHD, solriamfetol caused maternal toxicity that included decreased body weight gain, decreased food consumption, and hyperpnea.

At these maternally toxic doses, fetal toxicity included increased incidence of stillbirth, postnatal pup mortality, and decreased pup weight. Developmental toxicity in offspring after lactation day 20 included decreased body weight, decreased weight gain, and delayed sexual maturation. Mating and fertility of offspring were decreased at maternal doses 22 times the MRHD without affecting learning and memory.

🧒 Pediatric Use 24 words ▾

8.4Pediatric Use Safety and effectiveness in pediatric patients have not been established. Clinical studies of SUNOSI in pediatric patients have not been conducted.

🧓 Geriatric Use 96 words ▾

8.5Geriatric Use Of the total number of patients in the narcolepsy and OSA clinical studies treated with SUNOSI, 13% (123/930) were 65 years of age or over. No clinically meaningful differences in safety or effectiveness were observed between elderly and younger patients. Solriamfetol is predominantly eliminated by the kidney.

Because elderly patients are more likely to have decreased renal function, dosing may need to be adjusted based on eGFR in these patients. Consideration should be given to the use of lower doses and close monitoring in this population [see Dosage and Administration ( 2.5 )].

🆘 Overdosage 49 words ▾

10 OVERDOSAGE A specific reversal agent for SUNOSI is not available. Hemodialysis removed approximately 21% of a 75 mg dose in end stage renal disease patients. Overdoses should be managed with primarily supportive care, including cardiovascular monitoring. Consult with a Certified Poison Control Center at 1-800-222-1222 for latest recommendations.

🧬 Clinical Pharmacology ~3 min read ▾

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The mechanism of action of solriamfetol to improve wakefulness in patients with excessive daytime sleepiness associated with narcolepsy or obstructive sleep apnea is unclear. However, its efficacy could be mediated through its activity as a dopamine and norepinephrine reuptake inhibitor (DNRI).

12.2Pharmacodynamics Solriamfetol binds to the dopamine transporter and norepinephrine transporter with low affinity (Ki=14.2 µM and 3.7 µM, respectively), and inhibits the reuptake of dopamine and norepinephrine with low potency (IC 50 =2.9 μM and 4.4 μM, respectively). Solriamfetol has no appreciable binding affinity for the serotonin transporter (Ki=81.5 µM) and does not inhibit serotonin reuptake (IC 50 > 100 μM). Solriamfetol has no appreciable binding affinity to dopamine, serotonin, norepinephrine, GABA, adenosine, histamine, orexin, benzodiazepine, muscarinic acetylcholine, or nicotinic acetylcholine receptors.

Cardiac Electrophysiology The effect of solriamfetol 300 mg and 900 mg (twice and six times the maximum recommended dose, respectively) on the QTc interval was evaluated in a randomized, double-blind, placebo-, and positive-controlled (moxifloxacin 400 mg), 4-period, crossover study in 60 healthy subjects. A large increase in heart rate was observed in both solriamfetol treatment groups (mean change from baseline in HR of 21 and 27 bpm in the 300 and 900 mg groups, respectively, compared with 8 bpm in the placebo group).

These heart rate effects impact the interpretability of the QTc effects, particularly in the 900 mg group. In this study, solriamfetol 300 mg did not prolong the QTcF interval to a clinically relevant extent.

12.3Pharmacokinetics Solriamfetol exhibits linear kinetics over the dose range of 42 to 1008 mg (approximately 0.28 to 6.7 times the maximum recommended dosage). Steady state is reached in 3 days, and once‑daily administration is expected to result in minimal accumulation (1.06 times single‑dose exposure). Absorption The oral bioavailability of solriamfetol is approximately 95%.

Peak plasma concentration of solriamfetol occurs at a median T max of 2 hours (range 1.25 to 3.0 hours) post-dose under fasted conditions. Effect of Food Ingestion of solriamfetol with a high-fat meal resulted in minimal change in C max and AUC inf ; however, a delay of approximately 1 hour in T max was observed. Distribution The apparent volume of distribution of solriamfetol is approximately 199 L.

Plasma protein binding ranged from 13.3% to 19.4% over solriamfetol concentration range of 0.059 to 10.1 mcg/mL in human plasma. The mean blood‑to‑plasma concentration ratio ranged from 1.16 to 1.29. Elimination Solriamfetol exhibits first‑order elimination after oral administration.

The apparent mean elimination half‑life is about 7.1 hours. Metabolism Solriamfetol is minimally metabolized in humans. Excretion Approximately 95% of the dose was recovered in urine as unchanged solriamfetol, and 1% or less of the dose was recovered as the minor inactive metabolite N‑acetyl solriamfetol in a mass balance study.

Renal clearance (18.2 L/h) represented the majority of apparent total clearance (19.5 L/h). Active tubular secretion is likely involved in the renal elimination of the parent drug. Specific Populations Population PK analysis indicated that age, gender, and race do not have clinically relevant effects on the pharmacokinetics of solriamfetol.

No dose adjustments were made in clinical studies that enrolled patients ages 65 and above. Patients with Renal Impairment Exposures to solriamfetol in patients with renal impairment compared to subjects with normal renal function (eGFR ≥ 90 mL/min/1.73 m 2 ) are summarized in Figure 1. The half‑life of solriamfetol was increased approximately 1.2‑, 1.9‑, and 3.9‑fold in patients with mild (eGFR 60‑89 mL/min/1.73 m 2 ), moderate (eGFR 30–59 mL/min/1.73 m 2 ), or severe (eGFR <30 mL/min/1.73 m 2 ) renal impairment, respectively.

This Medication Guide has been approved by the U.S. Food and Drug Administration. SUN-USMG-003.000-20230630 Revised: 06/2023 MEDICATION GUIDE SUNOSI ® (suh-NOH-see) (solriamfetol) tablets, for oral use, CIV What is SUNOSI?

SUNOSI is a prescription medicine used to improve wakefulness in adults with excessive daytime sleepiness that is associated with narcolepsy or obstructive sleep apnea (OSA). It is not known if SUNOSI is safe and effective in children. SUNOSI is not for use to treat the underlying cause of airway obstruction in people with OSA.

SUNOSI does not take the place of using your continuous positive airway pressure (CPAP) machine or other devices that your healthcare provider has prescribed for the treatment of OSA. It is important that you continue to use these treatments as prescribed by your healthcare provider. SUNOSI is a federally controlled substance (CIV) because it contains solriamfetol that can be a target for people who abuse prescription medicines or street drugs.

Keep SUNOSI in a safe place to protect it from theft. Never give your SUNOSI to anyone else, because it may cause death or harm them. Selling or giving away SUNOSI may harm others and is against the law.

Tell your healthcare provider if you have ever abused or been dependent on alcohol, prescription medicines or street drugs. Do not take SUNOSI if you are taking or have stopped taking within the past 14 days a medicine used to treat depression called a monoamine oxidase inhibitor (MAOI). Before taking SUNOSI, tell your healthcare provider about all your medical conditions, including if you: have heart problems or have had a heart attack have had a stroke have high blood pressure have kidney problems or diabetes have high cholesterol in your blood have a history of mental health problems, including psychosis and bipolar disorders have a history of drug or alcohol abuse or addiction are pregnant or planning to become pregnant.

It is not known if SUNOSI will harm your unborn baby. Pregnancy Registry: There is a pregnancy registry for women who take SUNOSI during pregnancy. The purpose of this registry is to collect information about the health of you and your baby.

Talk to your healthcare provider about how you can take part in this registry. For more information or to participate in the registry, call 1-877-283-6220 or go to www.SunosiPregnancyRegistry.com are breastfeeding or plan to breastfeed. SUNOSI passes into your breastmilk.

Talk to your healthcare provider about the best way to feed your baby if you take SUNOSI. Tell your healthcare provider about all the medicines you take, including prescription or over-the-counter medicines, vitamins, or herbal supplements. SUNOSI and some other medicines may affect each other causing possible serious side effects.

SUNOSI may affect the way other medicines work and other medicines may affect the way SUNOSI works. Especially tell your healthcare provider if you take a medicine used to treat depression called a monoamine oxidase inhibitor (MAOI). Know the medicines you take.

Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine. How should I take SUNOSI? Take SUNOSI exactly as your healthcare provider tells you to.

Do not change your dose of SUNOSI without talking to your healthcare provider. Your healthcare provider may need to change the dose of SUNOSI until it is the right dose for you. Take SUNOSI by mouth 1 time each day when you first wake up.

Avoid taking SUNOSI within 9 hours of your planned bedtime. If you take SUNOSI too close to your bedtime, you may find it harder to go to sleep. SUNOSI can be taken with or without food.

Depending on your prescribed dose, your healthcare provider may tell you to swallow your SUNOSI tablet whole or split the SUNOSI tablet in half at the score line in the middle of the tablet. Ask your healthcare provider if you have questions about how to split the SUNOSI tablet in half the right way. If you take too much SUNOSI, call…
