How to use

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 baclofen oral solution 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 ) 2.1 Important 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. 2.2 Recommended Dosage Initiate baclofen oral solution 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…

Warnings

Important safety information

Abrupt discontinuation of baclofen has resulted in serious adverse reactions including death; therefore, reduce the dosage slowly when baclofen oral solution is discontinued. ( 5.1 ) Neonatal withdrawal symptoms can occur; gradually reduce the dosage and discontinue baclofen oral solution before delivery. ( 5.2 ) Baclofen oral solution 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 baclofen oral solution may be additive to those of alcohol and other CNS depressants. ( 5.3 ) Baclofen oral solution 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 ) 5.1 Adverse Reactions from Abrupt Withdrawal of Baclofen Oral Solution 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 baclofen oral solution is discontinued, unless the clinical situation justifies a rapid withdrawal. 5.2 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 baclofen oral solution is continued during pregnancy, gradually reduce the dosage and discontinue baclofen oral solution before delivery. If slow withdrawal is not feasible, advise the parents or caregivers of the exposed neonate of the potential for neonatal withdrawal. 5.3 Drowsiness and Sedation Drowsiness and sedation have been reported in up to 63% of patients taking baclofen, the active ingredient in baclofen oral solution [see Adverse Reactions ( 6.1 )] . Patients should avoid operation of automobiles or other dangerous machinery and activities made hazardous by decreased alertness when starting baclofen oral solution or increasing the dose until they know how the drug affects them. Advise patients that the central nervous system depressant effects of baclofen oral solution may be additive to those of alcohol and other CNS depressants. 5.4 Poor Tolerability in Stroke Patients Baclofen oral solution 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. 5.5 Exacerbation of Psychotic Disorders, Schizophrenia, or Confusional States Baclofen oral solution should be used with caution in patients suffering from psychotic disorders, schizophrenia, or confusional states. If treated with baclofen oral solution, these patients should be kept under careful surveillance because exacerbations of these conditions have been observed with oral baclofen administration. 5.6 Exacerbation of Autonomic Dysreflexia Baclofen oral solution should be used with caution in patients with a history of autonomic dysreflexia. The presence of nociceptive stimuli or abrupt withdrawal of baclofen oral solution may cause an autonomic dysreflexic episode. 5.7 Exacerbation of Epilepsy Baclofen oral solution should be used with caution in patients with epilepsy. Deterioration in seizure control has been reported in patients taking baclofen. 5.8 Posture and Balance Effects Baclofen oral solution 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. 5.9 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.

Interactions

How long does Baclofen stay in your body?

The elimination half-life of baclofen is about 5.7 hours — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. This is the apparent elimination half-life of the parent drug. Baclofen is not a prodrug and has no active metabolite that outlasts it — the label states it is excreted primarily by the kidney in unchanged form, so the half-life reflects renal clearance directly. Because of that, elimination is slower in people with reduced kidney function (renal impairment) and in older adults, in whom the drug can accumulate and the dose may need to be reduced. The label also notes large intersubject variation in absorption and/or elimination, so individual half-life can differ. Half-life is not the same as a drug-test detection window: baclofen is essentially cleared within about 72 hours of a dose, but detectability depends on the test.

It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.

Frequently asked questions

What does Ozobax treat?

Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
