Is this trial a fit for you?

Likely a good fit

Adults over 18 with shingles rash onset under 90 days, average pain score of at least 4 on an NRS, acceptable liver and kidney tests, and ability to consent are the intended participants.

Probably not a fit

Patients with disseminated or ocular shingles, prior desvenlafaxine use, known intolerance to the drug, or significant organ dysfunction are unlikely to benefit from joining this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with shingles that began within the past 90 days and who report moderate to severe pain will receive either desvenlafaxine plus conventional therapy or conventional therapy alone. Liver and kidney function limits are applied and prior use of desvenlafaxine or hypersensitivity excludes participation. Pain severity is measured using a numeric rating scale, and safety events will be monitored during the treatment period. The goal is to see if increasing serotonin and norepinephrine availability with desvenlafaxine provides better pain relief without substantially more adverse events.

Why it matters

Potential benefit: If successful, this could provide better pain relief for acute shingles and might reduce the chance of developing long-term postherpetic neuralgia.

How similar studies have gone: Other SNRIs have shown benefit for some types of neuropathic pain, but desvenlafaxine specifically for herpes zoster pain is relatively untested.
