Count on FLEQSUVY®:
An oral suspension for treating spasticity

Baclofen is a proven therapy for the treatment of spasticity

  • Healthcare professionals have been prescribing baclofen to treat spasticity for more than 40 years1
  • Baclofen is a commonly prescribed medication to treat spasticity in multiple sclerosis2
  • A phase 1 bioequivalence study was performed between FLEQSUVY® and baclofen oral tablets that demonstrated bioequivalence. The bioequivalence study established a scientific bridge for safety and efficacy between FLEQSUVY® and baclofen oral tablets1
  • While clinical trials with FLEQSUVY® have not been performed, previous studies with baclofen have demonstrated efficacy and safety for the indicated use of FLEQSUVY®3

FLEQSUVY® is a liquid formulation of baclofen1

  • Pharmacokinetic Summary:
  • Absorption: Peak plasma concentrations were achieved in about 1 hour from administration of FLEQSUVY® in the fasted state. The apparent elimination half-life is about 5.6 hours
  • Effect of Food: Administration of FLEQSUVY® with a high-fat meal resulted in a 9% decrease in the AUC and a 33% decrease in Cmax compared to the fasted state
  • Elimination: Baclofen is excreted primarily by the kidneys in unchanged form, and there is relatively large intersubject variation in absorption and/or elimination

AUC=area under the curve; Cmax=maximum plasma concentration.

A well-documented safety profile1

  • Clinical trials are conducted under widely varying conditions; therefore adverse reaction rates may vary in different trials
  • In the bioavailability study for FLEQSUVY®, no deaths occurred and all treatment-associated adverse events were assessed as mild in intensity. One subject discontinued due to increased blood creatinine phosphokinase and increased blood creatinine
  • In clinical trials for baclofen, the most common adverse reactions* were transient drowsiness (10% to 63%) and dizziness and weakness (5% to 15%)
  • Other adverse reactions (≥1%) were nausea, confusion, hypotension, headache, insomnia, constipation, urinary frequency, and fatigue
  • The following laboratory tests have been found to be abnormal in patients receiving baclofen: increased SGOT (serum glutamic oxaloacetic transaminase), elevated alkaline phosphatase, and elevation of blood sugar

Important Safety Information for FLEQSUVY® (baclofen oral suspension)

  • FLEQSUVY is indicated for the treatment of spasticity resulting from multiple sclerosis, particularly for the relief of flexor spasms and concomitant pain, clonus, and muscular rigidity.
  • FLEQSUVY may also be of some value in patients with spinal cord injuries and other spinal cord diseases.

Limitations of Use: FLEQSUVY is not indicated in the treatment of skeletal muscle spasm resulting from rheumatic disorders.

FLEQSUVY is a concentrated formulation. Verify the strength and the dose of the product prior to prescribing, dispensing, and administering.

Important Safety Information


FLEQSUVY is contraindicated in patients with hypersensitivity to baclofen.


Adverse Reactions from Abrupt Withdrawal of FLEQSUVY: 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 FLEQSUVY is discontinued, unless the clinical situation justifies a rapid withdrawal.

Neonatal 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 FLEQSUVY is continued during pregnancy, gradually reduce the dosage and discontinue FLEQSUVY before delivery. If slow withdrawal is not feasible, advise the parents or caregivers of the exposed neonate of the potential for neonatal withdrawal.

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

Poor Tolerability in Stroke Patients: FLEQSUVY 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.

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

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

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

Posture and Balance Effects: FLEQSUVY 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.

Ovarian 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 patients who were treated with oral baclofen for up to one year. In most cases, these cysts disappeared spontaneously while patients continued to receive the drug. Ovarian cysts are estimated to occur spontaneously in approximately 1% to 5% of the normal female population.


The most common (up to 15% or more) adverse reactions in patients were drowsiness, dizziness, and weakness.


CNS Depressants and Alcohol: FLEQSUVY can cause CNS depression, including drowsiness and sedation, which may be additive when used concomitantly with other CNS depressants or alcohol.


Pregnancy: Based on animal data, may cause fetal harm.

Because baclofen is excreted unchanged through the kidneys it may be necessary to reduce the dosage in patients with impaired renal function.
