Updated: Dec 21, 2015

Medication Summary

Medical therapy is only for symptomatic control. Definitive treatment to date is surgical in nature.


Centrally acting antispasticity agents

Class Summary

Antispasticity agents are indicated when spasticity interferes with function, causes pain, or interferes with sleep.

Baclofen (Lioresal)


May induce the hyperpolarization of afferent terminals and inhibit both monosynaptic and polysynaptic reflexes at the spinal level.


Tricyclic antidepressants

Class Summary

Although not an FDA-labeled use, TCAs are considered first-line treatment by specialists to treat many types of neuropathic pain. Doses used generally are less than those required to treat depression.

Amitriptyline (Elavil)


Analgesic for certain chronic and neuropathic pain.



Class Summary

Although not an FDA-labeled use, anticonvulsants are used commonly by specialists to treat neuropathic pain. Gabapentin has the advantage of reduced toxicity and side effects.

Gabapentin (Neurontin)


Has anticonvulsant properties and antineuralgic effects; however, the exact mechanism of action is unknown. Structurally related to GABA but does not interact with GABA receptors. Titration to effect can take place over several days (300 mg on day 1, 300 mg bid on day 2, and 300 mg tid on day 3).



Class Summary

Reduce gastrointestinal, salivary, and sudomotor (sweat gland) activity and can alleviate excess sweating in patients with PTS.

Scopolamine (Transderm Scop)


Blocks action of acetylcholine at parasympathetic sites in smooth muscle, secretory glands, and the CNS. Antagonizes histamine and serotonin action.

Transdermal scopolamine may be the most effective agent for motion sickness. Its use in vestibular neuronitis is limited by its slow onset of action.

Anticholinergic activity used in the treatment of nausea but also can inhibit the secretion of saliva and sweat.


Narcotic analgesics

Class Summary

May be necessary in patients whose pain is not controlled with other agents. Long-acting agents are preferred for chronic use.

Oxycodone SA (OxyContin)


Indicated for the relief of moderate to severe pain.

This illustration shows a T1-weighted, cervical magnetic resonance imaging (MRI) scan of multiple syrinx cavities (arrows). Note the lowest thin cavity extending into the thoracic spinal cord.
This T2-weighted magnetic resonance imaging (MRI) scan (same patient as above) delineates the syrinx cavity. Note the spinal cord edema extending rostrally from the upper limit of the cavity.
T2-weighted magnetic resonance imaging (MRI) scan (same patient as above) after patient underwent expansile duraplasty. Note dramatic reduction in size of the main syrinx cavity (white).
T2-weighted sagittal image of large, multiloculated cervical syrinx extending into brainstem. Patient had preserved functional status.
T1-weighted magnetic resonance imaging (MRI) scan of a slender syrinx (arrow) extending from the C5 vertebral level. This syrinx extends beyond the image to an area of spinal cord disruption at the T3 vertebral level.
Same patient as in image above, with the magnetic resonance imaging (MRI) scan slightly farther down the cervicothoracic region of the spine
T2 proton density magnetic resonance imaging (MRI) scan demonstrating syrinx cavity (arrow) extending from approximately C6-C7 to T2. The syrinx cavity is 9 mm at its widest dimension. The spinal cord is reduced to a thin membrane at this level and is atrophic below.
T1-weighted image demonstrating a large, multiloculated cervical syrinx cavity. This is a recurrent syrinx, having come back despite an attempt at drainage utilizing expansile duraplasty.
