- Subject is in generally good health other than a history of postherpetic neuralgia, determined by pre-study medical evaluation (medical history, physical examination including examination of the treatment area, and vital signs) and without evidence of underlying unstable acute or chronic systemic disease, e.g. diabetes.
- Subject has experienced on average, moderate to severe chronic postherpetic neuralgia restricted to the distribution of the affected trigeminal nerve or its divisions for at least 12 months after healing of a herpes zoster skin rash.

- Males or females between 21 to 80 years of age, inclusive.
- Non-pregnant, non-lactating females of childbearing potential who agree to use medically acceptable forms of birth control (abstinence, hormonal contraceptives, diaphragm with spermicide, condom with spermicide, or intrauterine device) throughout the study or females of non-childbearing potential (surgically sterile \[hysterectomy or bilateral tubal ligation\] or post-menopausal ≥ 1 year).

Concurrent medications and stable dose requirements are listed in Table 3.
- Clinical, historical or previous laboratory evidence of significant cardiovascular, renal, gastrointestinal, pulmonary, hepatic, endocrine, neurological, psychological, or other systemic disease that, in the opinion of the Investigator, might confound the results of the study or pose an additional risk to the subject.

- Subject received neurolytic or neurosurgical therapy for this or previous episodes of postherpetic neuralgia.
- Use of any restricted medication within the given time period prior to the Baseline Period and throughout the study (see Table 1).
- Subject has a history of alcohol and/or drug abuse within the past year.
- Subject has previously participated in a Civamide study.
- Subject has participated in another investigational study or taken another investigational drug within the past 30 days.
