Postherpetic neuralgia (PHN) is a common complication of herpes zoster (shingles) characterized by persistent nerve pain following the resolution of the rash. The recommended treatment for PHN often includes medications that target neuropathic pain.

Tricyclic antidepressants (TCAs) are particularly effective in managing neuropathic pain conditions, including postherpetic neuralgia. This effectiveness is attributed to their ability to modulate neurotransmitter levels, particularly norepinephrine and serotonin, which play a role in pain pathways. By enhancing the descending inhibitory control of pain, TCAs can help reduce the unpleasant sensation of pain in individuals with PHN.

In addition to their analgesic properties, TCAs also have sedative effects that can benefit patients who struggle with sleep disturbances related to chronic pain. The typical dosing for TCAs, like amitriptyline or nortriptyline, starts low and is gradually increased based on the individual's response, balancing efficacy with potential side effects.

Other drug classes, while potentially useful in certain contexts, do not have the same level of evidence supporting their use specifically for postherpetic neuralgia. SSRIs, atypical antidepressants, and benzodiazepines may help with anxiety or mood disorders
