Controlling the pain of postherpetic neuralgiaPostherpetic neuralgia is ongoing pain that develops
in some people who have
shingles. Postherpetic neuralgia causes facial nerve
problems, headaches, and persistent pain that last for at least 30 days and may
continue for months to years. However, most cases of postherpetic neuralgia end
within the first year. Talk with your health professional about the following methods that
may relieve your pain. Over-the-counter medications - Pain medications (analgesics), such as
acetaminophen, aspirin, or ibuprofen, may be enough to help control
pain.
- Anesthetics (such as benzocaine) are available in forms that
you can apply directly to the skin for pain relief. Anesthetics cause partial
or complete loss of feeling when applied to a particular area of skin around
the area of pain.
- Capsaicin is a naturally occurring
substance found in hot chili peppers. Medications containing capsaicin, such as
Zostrix, may relieve the pain of postherpetic neuralgia. When applied to the
skin, capsaicin blocks the skin's nerve impulses, stopping pain without
interfering with other sensations. Do not apply capsaicin to the skin during
the active rash stage; this could cause extreme aggravation of the rash.
Capsaicin sometimes causes burning, stinging, or redness of the skin.
Prescription medications - The Lidoderm patch contains lidocaine anesthetic.
You apply it directly to the painful skin area. The lidocaine patch numbs the
area, is simple to use, and causes no known serious side effects.
- Corticosteroid injections, sometimes used in
combination with other medications, reduce the pain and area of skin affected
by postherpetic neuralgia.
- Tricyclic antidepressants (such as
amitriptyline) interfere with the chemical substances that send pain
messages.
- Anticonvulsants (such as gabapentin) can relieve pain by
calming the nerve pathways that send pain signals.
- Nerve block
injections (anesthetic shots around the infected nerve) temporarily relieve
pain.
- Opioids (such as codeine) suppress the
feeling of pain.
