📖 What it is MedlinePlus · NLM

Baclofen is used to treat pain and certain types of spasticity (muscle stiffness and tightness) from multiple sclerosis, spinal cord injuries, or other spinal cord diseases. Baclofen is in a class of medications called skeletal muscle relaxants. Baclofen acts on the spinal cord nerves and decreases the number and severity of muscle spasms caused by multiple sclerosis or spinal cord conditions. It also relieves pain and improves muscle movement.

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 systemPer mLPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.

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.

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 OZOBAX DS 10 MG/5 ML SOLUTION?
Yes — an FDA-approved generic equivalent is listed in the FDA Orange Book for OZOBAX DS 10 MG/5 ML SOLUTION. 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.

2 DOSAGE AND ADMINISTRATION Baclofen oral solution is available in multiple concentrations; include both the total dose in mg and the total dose in volume on prescriptions ( 2.1 ) Initiate OZOBAX DS with a low dosage, preferably in divided doses, administered orally. Increase gradually based on clinical response and tolerability. ( 2.2 ) The maximum dosage is 80 mg daily (20 mg four times a day).

( 2.2 ) When discontinuing, reduce the dosage slowly. ( 2.3 )

2.1Important Dosage Information Baclofen oral solution is available in multiple concentrations; ensure accuracy when prescribing, dispensing and administering baclofen oral solution to avoid dosing errors due to confusion between mg and mL, and with other baclofen oral solutions of different concentrations. When writing prescriptions, include both the total dose in mg and the total dose in volume.

2.2Recommended Dosage Initiate OZOBAX DS with a low dosage, preferably in divided doses, administered orally. The following gradually increasing dosage regimen is suggested, but should be adjusted based on clinical response and tolerability: 5 mg (2.5 mL) three times a day for three days 10 mg (5 mL) three times a day for three days 15 mg (7.5 mL) three times a day for three days 20 mg (10 mL) three times a day for three days Additional increases may be necessary up to the maximum recommended dosage of 80 mg daily (20 mg four times a day).

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS Abrupt discontinuation of baclofen has resulted in serious adverse reactions including death; therefore, reduce the dosage slowly when OZOBAX DS is discontinued. ( 5.1 ) Neonatal withdrawal symptoms can occur; gradually reduce the dosage and discontinue OZOBAX DS before delivery. ( 5.2 ) OZOBAX DS can cause drowsiness and sedation.

Patients should avoid the operation of automobiles or other dangerous machinery until they know how the drug affects them. Advise patients that the central nervous system effects of OZOBAX DS may be additive to those of alcohol and other CNS depressants. ( 5.3 ) OZOBAX DS can cause exacerbation of the following: psychotic disorders, schizophrenia, or confusional states; autonomic dysreflexia; epilepsy.

Use with caution in patients with these conditions ( 5.5 , 5.6 , 5.7 )

5.1Adverse Reactions from Abrupt Withdrawal of OZOBAX DS Abrupt discontinuation of baclofen, regardless of the cause, has resulted in adverse reactions that include hallucinations, seizures, high fever, altered mental status, exaggerated rebound spasticity, and muscle rigidity, that in rare cases has advanced to rhabdomyolysis, multiple organ-system failure, and death. Therefore, reduce the dosage slowly when OZOBAX DS is discontinued, unless the clinical situation justifies a rapid withdrawal.

5.2Neonatal Withdrawal Symptoms Withdrawal symptoms in neonates whose mothers were treated with oral baclofen throughout pregnancy have been reported starting hours to days after delivery. The symptoms of withdrawal in these infants have included increased muscle tone, tremor, jitteriness, and seizure. If the potential benefit justifies the potential risk to the fetus and OZOBAX DS is continued during pregnancy, gradually reduce the dosage and discontinue OZOBAX DS before delivery.

If slow withdrawal is not feasible, advise the parents or caregivers of the exposed neonate of the potential for neonatal withdrawal.

5.3Drowsiness and Sedation Drowsiness and sedation have been reported in up to 63% of patients taking baclofen, the active ingredient in OZOBAX DS [see Adverse Reactions ( 6.1 )] . Patients should avoid operation of automobiles or other dangerous machinery and activities made hazardous by decreased alertness when starting OZOBAX DS or increasing the dose until they know how the drug affects them. Advise patients that the central nervous system depressant effects of OZOBAX DS may be additive to those of alcohol and other CNS depressants.

5.4Poor Tolerability in Stroke Patients OZOBAX DS should be used with caution in patients who have had a stroke. Baclofen has not significantly benefited patients with stroke. These patients have also shown poor tolerability to the drug.

5.5Exacerbation of Psychotic Disorders, Schizophrenia, or Confusional States OZOBAX DS should be used with caution in patients suffering from psychotic disorders, schizophrenia, or confusional states. If treated with OZOBAX DS, these patients should be kept under careful surveillance because exacerbations of these conditions have been observed with oral baclofen administration.

5.6Exacerbation of Autonomic Dysreflexia OZOBAX DS should be used with caution in patients with a history of autonomic dysreflexia. The presence of nociceptive stimuli or abrupt withdrawal of OZOBAX DS may cause an autonomic dysreflexic episode.

5.7Exacerbation of Epilepsy OZOBAX DS should be used with caution in patients with epilepsy. Deterioration in seizure control has been reported in patients taking baclofen.

5.8Posture and Balance Effects OZOBAX DS should be used with caution in patients where spasticity is utilized to sustain upright posture and balance in locomotion or whenever spasticity is utilized to obtain increased function.

5.9Ovarian Cysts A dose-related increase in incidence of ovarian cysts was observed in female rats treated chronically with oral baclofen. Ovarian cysts have been found by palpation in about 4% of the multiple sclerosis pat… [Excerpted — this section continues on DailyMed.]

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Adverse Reactions from Abrupt Withdrawal of OZOBAX DS [see Warnings and Precautions ( 5.1 )] Neonatal Withdrawal Symptoms [see Warnings and Precautions ( 5.2 )] Drowsiness and Sedation [see Warnings and Precautions ( 5.3 )] Poor Tolerability in Stroke Patients [see Warnings and Precautions ( 5.4 )] Exacerbation of Psychotic Disorders, Schizophrenia, or Confusional States [see Warnings and Precautions ( 5.5 )] Exacerbation of Autonomic Dysreflexia [see Warnings and Precautions ( 5.6 )] Exacerbation of Epilepsy [see Warnings and Precautions ( 5.7 )] Posture and Balance Effects [see Warnings and Precautions ( 5.8 )] Ovarian Cysts [see Warnings and Precautions ( 5.9 )] The most common (up to 15% or more) adverse reactions in patients were drowsiness, dizziness, and weakness.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Metacel Pharmaceuticals, LLC at 1-833-469-6229 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 most common adverse reaction is transient drowsiness.

7 DRUG INTERACTIONS

7.1CNS Depressants and Alcohol OZOBAX DS can cause CNS depression, including drowsiness and sedation, which may be additive when used concomitantly with other CNS depressants or alcohol [see Warnings and Precautions ( 5.3 )].

👥 Use in Specific Populations ~2 min read ▾

8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm ( 8.1 ) Because baclofen is excreted unchanged through the kidneys it may be necessary to reduce the dosage in patients with impaired renal function. ( 8.6 )

8.1Pregnancy Risk Summary There are no adequate data on the developmental risk associated with the use of OZOBAX DS in pregnant women. Oral administration of baclofen to pregnant rats resulted in an increased incidence of fetal structural abnormalities at a dose which was also associated with maternal toxicity. The background risk of major birth defects and miscarriage for the indicated population is unknown.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Fetal/Neonatal adverse reactions Ozobax DS may increase the risk of late-onset neonatal withdrawal symptoms [see Warnings and Precautions ( 5.2 )] . Data Animal Data Baclofen given orally has been shown to increase the incidence of omphaloceles (ventral hernias) in fetuses of rats given approximately 13 times on a mg/kg basis, or 3 times on a mg/m 2 basis, the maximum oral dose recommended for human use; this dose also caused reductions in food intake and weight gain in the dams.

This abnormality was not seen in mice or rabbits.

8.2Lactation Risk Summary At recommended oral doses, baclofen is present in human milk. There are no human data on the effects of baclofen on milk production. There are no adequate data on the effects of baclofen on the breastfed infant.

Withdrawal symptoms can occur in breastfed infants when maternal administration of OZOBAX DS is stopped, or when breastfeeding is stopped [see Warnings and Precautions ( 5.2 )] . The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for OZOBAX DS and any potential adverse effects on the breastfed infant from OZOBAX DS or from the underlying maternal condition.

8.4Pediatric Use Safety and effectiveness in pediatric patients below the age of 12 have not been established.

8.5Geriatric Use In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

8.6Renal Impairment Because baclofen is primarily excreted unchanged through the kidneys, OZOBAX DS should be given with caution to patients with renal impairment, and it may be necessary to reduce the dosage.

🆘 Overdosage 49 words ▾

10 OVERDOSAGE

10.1Symptoms of Baclofen Overdose Patients may present in coma or with progressive drowsiness, lightheadedness, dizziness, somnolence, accommodation disorders, respiratory depression, seizures, or hypotonia progressing to loss of consciousness.

10.2Treatment for Overdose The treatment of baclofen overdose includes gastric decontamination, maintaining an adequate airway and respirations.

🧬 Clinical Pharmacology 197 words ▾

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The precise mechanism of action of baclofen is not fully understood. Baclofen inhibits both monosynaptic and polysynaptic reflexes at the spinal level, possibly by decreasing excitatory neurotransmitter release from afferent terminals, although actions at supraspinal sites may also occur and contribute to its clinical effect. Baclofen is a structural analog of the inhibitory neurotransmitter gamma- aminobutyric acid (GABA), and may exert its effects by stimulation of the GABA B receptor subtype.

12.2Pharmacodynamics Baclofen has been shown to have general CNS depressant properties, as indicated by the production of sedation with tolerance, somnolence, ataxia, and respiratory and cardiovascular depression [see Warnings and Precautions ( 5.3 ), Adverse Reactions ( 6.1 ), and Overdosage ( 10.1 )].

12.3Pharmacokinetics A pharmacokinetic study in heathy adult male subjects under fasting conditions at 20 mg dose level demonstrated similar bioavailability for baclofen oral solution (5 mg/5 mL) and oral tablets. The peak plasma concentrations were achieved in about 0.75 hours from oral solution and the apparent elimination half-life is about 5.7 hours. Baclofen is excreted primarily by the kidney in unchanged form, and there is relatively large intersubject variation in absorption and/or elimination.

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

Medicare Part D (outpatient prescription) spending for Ozobax Ds — 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 Ozobax Ds. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The 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 Rosemont Pharmaceuticals 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 1 other package presentation of this same product, including 473 ml (69528-0302-16). 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?
Rosemont Pharmaceuticals 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.
