Summary
Intravenous Immunoglobulin (IVIG) is tracked by OSMF as an investigational option for Lyme / PTLDS; no regulator has approved it for this indication, and most post-viral conditions have no approved disease-modifying therapy at all. No registered clinical trial in this database tests Intravenous Immunoglobulin (IVIG) specifically in Lyme / PTLDS. The evidence below comes from published literature only, so any clinical signal has not yet been tested prospectively against this condition in a registered study. The literature layer holds 8 publications for this pair: 8 curated references. The dated items are from 2026. Items here are search-derived or curated references rather than classified trial reports; treat them as leads to read, not as graded evidence.
Lyme Disease and Post-Treatment Lyme Disease Syndrome is tracked on the OSMF post-viral programme alongside ME/CFS, Long COVID, POTS and MCAS. Across the programme, 4 candidate agents are logged for Lyme / PTLDS, most of them preliminary; this page isolates the record for one of them.

How the evidence score is calculated
- Each registered trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5). The trial component is capped at 30.
- Each literature item scores by design (Cochrane review 5, meta-analysis 4, systematic review 3, RCT 3, clinical trial publication 2, curated reference 1.5, other PubMed record 1). The literature component is capped at 30.
- The existing evidence tier adds 15 (A / Strong), 10 (B / Moderate), 5 (C / Preliminary) or 0 (D / Anecdotal).
- Agents approved for any indication (max clinical phase 4) add 5, because an approved agent has an established safety profile that lowers the barrier to repurposing trials.
- The score ranks what has been studied, not what works. It does not read effect sizes or directions of effect.

Frequently asked questions
Is Intravenous Immunoglobulin (IVIG) approved for Lyme / PTLDS?
Intravenous Immunoglobulin (IVIG) is tracked by OSMF as an investigational option for Lyme / PTLDS; no regulator has approved it for this indication, and most post-viral conditions have no approved disease-modifying therapy at all. Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Intravenous Immunoglobulin (IVIG) in clinical trials for Lyme / PTLDS?
No registered clinical trial in this database tests Intravenous Immunoglobulin (IVIG) specifically in Lyme / PTLDS. The evidence below comes from published literature only, so any clinical signal has not yet been tested prospectively against this condition in a registered study.
What does the evidence show for Intravenous Immunoglobulin (IVIG) in Lyme / PTLDS?
The record for Intravenous Immunoglobulin (IVIG) in Lyme / PTLDS rests on 8 publications without a registered trial. This is a lead for hypothesis generation, not evidence of efficacy. OSMF's existing evidence tier for this pair is B (Moderate), taken from the OSMF therapeutic agent database, which grades agents by the volume and design of condition-specific evidence rather than by effect size.
