Gablofen Overview

Updated: 

Gablofen is a prescription medication used to relieve spasms and increased muscle tone caused by multiple sclerosis or spinal injury. This medication belongs to a group of drugs called muscle relaxants. Although the way it works is not fully understood, Gablofen may decrease the number and severity of muscle spasms by inhibiting nerve signals.

This medication comes as an injectable liquid to be given directly into the spinal fluid by a healthcare professional.

Common side effects include weakness, drowsiness, and dizziness. Do not drive or operate machinery until you know how this medication affects you.

Gablofen and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Gablofen falls into category C. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

 

Gablofen and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

Gablofen, when taken orally, has been detected in human breast milk. It is not known whether detectable levels of drug are present in milk of nursing mothers receiving Gablofen. Because of the potential for serious adverse reactions in nursing infants from Gablofen, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. 

Gablofen Usage

Gablofen is also available in an injectable form to be used in more severe cases. It is given through a pump into the spinal fluid.

Gablofen Dosage

Gablofen for injection

A doctor will surgically place the pump that will deliver the dose of the medication. The dose of intrathecal Gablofen will be different for different patients and will depend on the type of muscle tightness that you have.

 

Gablofen Overdose

Since this medication is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.

Gablofen FDA Warning

Injectable:

Abrupt discontinuation of intrathecal (into the spine) Gablofen, regardless of the cause, has resulted in sequelae that include 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.  

Prevention of abrupt discontinuation of intrathecal Gablofen requires careful attention to programming and monitoring of the infusion system, refill scheduling and procedures, and pump alarms. Patients and caregivers should be advised of the importance of keeping scheduled refill visits and should be educated on the early symptoms of Gablofen withdrawal.  Special attention should be given to patients at apparent risk (e.g. spinal cord injuries at T-6 or above, communication difficulties, history of withdrawal symptoms from oral or intrathecal Gablofen). Consult the technical manual of the implantable infusion system for additional postimplant clinician and patient information.
