Anticonvulsants (pregabalin [Lyrica],
gabapentin [Neurontin]) have been shown to
lessen the pain of PHN probably by stabilizing abnormal electrical activity in
your nervous system.
Antidepressants (venlafaxine [Effexor],
duloxetine [Cymbalta]) are often prescribed in lower doses than for depression.
Because some drugs (opioids) can be addictive
and because some patients may need long-term treatments (over one year),
consultation with a pain-management specialist may be advised. Some individuals
claim tamanu oil rubbed into the affected may reduce the symptoms of PHN. One
small study and a few case reports indicate that acupuncture can be helpful in
relieving the pain of PHN. Infrequently, other methods are used. TENS
(transcutaneous electrical nerve stimulation) devices are designed to interrupt
the body's pain sensations while nerve blocks (short-term chemical nerve
sensation blockade) and nerve ablation (surgically cutting a nerve) are also
used. Results vary but the methods often do not give lasting pain relief.
