Fleqsuvy (Baclofen Oral Suspension 5 mg/mL, 200 mL): Comprehensive Patient Information for Canada

Basic Product Information

Mechanism of Action

In simple terms: Baclofen is a muscle relaxant that works in the spinal cord to reduce muscle stiffness and spasms. It helps relax tight, overactive muscles caused by conditions like multiple sclerosis or spinal cord injury, which can improve your ability to move and make daily activities and physiotherapy easier. The oral suspension form is designed for patients who have difficulty swallowing tablets or need precise, flexible dosing.

For specialists: Baclofen is a derivative of gamma-aminobutyric acid (GABA) and a selective agonist at GABAB receptors. The precise mechanism of action has not been fully determined. It acts mainly at the spinal cord level to inhibit the transmission of both monosynaptic and polysynaptic reflexes, possibly by hyperpolarization of primary afferent fiber terminals resulting in antagonism of the release of putative excitatory transmitters (i.e., glutamic and aspartic acids). Actions at supraspinal sites may also be involved. Baclofen has general central nervous system (CNS)-depressant actions. Fleqsuvy oral suspension is a concentrated formulation (5 mg/mL), and the dose should be verified prior to dispensing.

Pharmacokinetics

• Absorption: Baclofen is rapidly and almost completely absorbed from the gastrointestinal tract after an oral dose. Peak plasma concentrations occur about 0.5 to 3 hours after ingestion, but the rate and extent of absorption vary between patients and may vary inversely with the dose.
• Metabolism: About 15% is metabolized in the liver. The main metabolite is β-(p-chlorophenyl)-γ-hydroxybutyric acid, which is pharmacologically inactive.
• Distribution: The distribution volume of baclofen amounts to 0.7 L/kg. Baclofen crosses the placenta and is distributed into breast milk. About 30% of baclofen is bound to plasma proteins.
• Elimination: The elimination half-life of baclofen is about 3 to 4 hours in plasma. Baclofen is eliminated largely in unchanged form. Within 72 hours approximately 75% of the dose is excreted via the kidneys, approximately 5% of this quantity being in the form of metabolites. The remainder of the dose, 5% of which is in metabolite form, is excreted in the faeces.
• Onset of Action: Following oral administration, symptomatic relief typically begins within hours.
• Duration of Action: The therapeutic effect is maintained with continued dosing. The half-life of 3 to 4 hours supports multiple daily dosing.

Uses in Daily Life and Best Practice Advice

Baclofen oral suspension is prescribed for the treatment of spasticity. Your physician will determine the appropriate use and dose based on your specific medical situation.

• Typical Uses: Treatment of spasticity resulting from multiple sclerosis, particularly for the relief of flexor spasms and concomitant pain, clonus, and muscular rigidity. It may also be of some value in patients with spinal cord injuries and other spinal cord diseases. Baclofen is not indicated for the treatment of skeletal muscle spasm resulting from rheumatic disorders.
• Administration: Fleqsuvy is a concentrated formulation (5 mg/mL). The dose should be measured accurately using the provided oral dosing syringe or a calibrated measuring device. The suspension should be shaken well before each use. It can be administered orally or via a nasogastric (NG) feeding tube.
• Monitoring: Your physician will monitor your response to treatment and adjust the dose as needed. Regular follow-up is important to assess effectiveness and manage side effects.
• Do Not Stop Without Medical Advice: Do not stop taking baclofen abruptly. Abrupt discontinuation can cause withdrawal symptoms including high fever, altered mental status, exaggerated rebound spasticity, and muscle rigidity, and can be life-threatening.

Morning vs. Evening Dosing

Baclofen oral suspension is typically taken three times daily. There is no specific clinical recommendation for morning versus evening dosing. However, because drowsiness is a common side effect, your physician may suggest adjusting the timing to minimize daytime sedation. Always follow the schedule recommended by your physician.

• Divided Dosing: The daily dose is usually divided into three doses taken throughout the day.
• Consistency: Take baclofen at the same times each day to ensure consistent effects.
• Missed Dose: If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time.
• Professional Guidance: Your healthcare provider may adjust the frequency and timing based on your response to treatment.

Administration With or Without Food

Baclofen oral suspension can be taken with or without food. Food does not significantly affect the absorption of baclofen. This flexibility makes it convenient to take at any time of day.

• Shake the bottle well before measuring each dose.
• Use the oral dosing syringe provided with the product or a calibrated measuring device to ensure accurate dosing.
• Baclofen oral suspension can be taken with or without food.
• Avoid drinking alcohol while taking baclofen, as it can increase drowsiness and the risk of serious side effects.
• If administering via a nasogastric feeding tube, flush the tube with 15 to 30 mL of purified water before administration, draw the required dose into an appropriate syringe, administer the dose, and flush the tube with at least 25 mL of purified water afterward.

Interaction Warnings

Indications for Baclofen Oral Suspension

"Off-label" means use outside the official approved indication, usually based on current medical guidelines and scientific evidence.

Dosing According to Clinical Indication

Doses should always be adjusted according to the advice of your physician and depending on your health condition. Fleqsuvy is a concentrated formulation; verify the dose of the product prior to dispensing. Do not stop abruptly; gradual dose reduction is required to prevent withdrawal syndrome.

Comparison: Baclofen oral suspension (Fleqsuvy) is a concentrated liquid formulation designed for patients who have difficulty swallowing tablets or require flexible dosing. It offers the same therapeutic benefits as oral baclofen tablets. In Canada, where Fleqsuvy is not commercially available, baclofen oral suspension can be prepared by compounding pharmacies at various concentrations (commonly 1 mg/mL, 5 mg/mL, or 10 mg/mL). The choice between tablets and suspension depends on patient preference, swallowing ability, and the need for precise dose titration. Your physician will determine the best option for your specific condition.

Recent Research and Clinical Guidelines (2022–2026)

• Fleqsuvy was approved by the FDA as a concentrated oral suspension formulation of baclofen (5 mg/mL) for the treatment of spasticity resulting from multiple sclerosis, spinal cord injuries, and other spinal cord diseases.
• A 2026 systematic review characterized the clinical presentations and management of oral baclofen toxicity and withdrawal. Baclofen toxicity commonly presented with central nervous system depression, seizures, and respiratory depression, particularly at high doses. Baclofen withdrawal commonly manifested with severe psychiatric disturbances, delirium, agitation, and autonomic instability, typically emerging within 1–4 days after abrupt discontinuation. Clinicians should exercise caution when prescribing baclofen, particularly at higher doses.
• Research continues to explore the role of baclofen in various clinical settings, including its use as a muscle relaxant in patients with cirrhosis (Child A and B: safe; Child C: use with caution, initiate at low dose and titrate slowly).
• Compounded baclofen oral suspensions remain an important option in Canada for patients who cannot swallow tablets, particularly in pediatric and geriatric populations. Canadian hospitals, including SickKids and CHEO, have established standardized compounding formulas for baclofen oral suspension at 5 mg/mL.
