Encouraging direction, but not yet definitive.
This retrospective cohort study using propensity score matching found that tirzepatide use was associated with reduced incidence of carpal tunnel syndrome compared to GLP-1RA and other anti-obesity medications, with hazard ratios of 0.82 and 0.75 respectively. While the design is observational with inherent confounding risk and sample size is unreported, the findings across multiple comparisons and sensitivity analyses suggest a potential protective association that warrants prospective validation.
Multicenter retrospective cohort study with propensity score matching and target trial emulation. Adults aged ≥18 years who are overweight or obese initiating tirzepatide, GLP-1RAs (glucagon-like peptide-1 receptor agonists), or other anti-obesity medications (orlistat or phentermine) between January 2022 and December 2024. Intervention: Tirzepatide initiation. Compared with: GLP-1 receptor agonists and other anti-obesity medications (orlistat or phentermine). TriNetX US Collaborative Network; specific number of centres not stated.
Tirzepatide versus GLP-1RAs: HR 0.82 (95% CI 0.71–0.95) for incident CTS; no significant difference in CTS surgery Tirzepatide versus other anti-obesity medications: HR 0.75 (95% CI 0.65–0.85) for incident CTS and HR 0.64 (95% CI 0.44–0.94) for CTS surgery Propensity score matching (1:1) achieved well-balanced cohorts across comparisons
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
If confirmed in prospective studies, reduced CTS risk with tirzepatide could represent an additional benefit in weight management and metabolic disease. Clinicians should interpret this as hypothesis-generating pending prospective data, as observational design cannot rule out confounding by indication or unmeasured factors.
Retrospective cohort study with propensity score matching showing reduced CTS risk with tirzepatide versus comparators, but observational design, potential residual confounding, and surrogate clinical outcomes limit strength.

This study aimed to evaluate the association between tirzepatide use and the risk of carpal tunnel syndrome (CTS) and CTS surgery compared with both glucagon-like peptide-1 receptor agonists (GLP-1RAs) and other anti-obesity medications in individuals who are overweight or obese. We conducted a multicenter retrospective cohort study using the TriNetX US Collaborative Network with a target trial emulation design. Adults aged ≥ 18 years who are overweight or obese and initiated tirzepatide, GLP-1RAs, or other anti-obesity medications (including orlistat or phentermine) between January 2022 and December 2024 were included. Propensity score matching (1:1) was applied to balance demographics, BMI, comorbidities, and socioeconomic variables. Primary outcomes were incident CTS and CTS surgery, with hazard ratios (HRs) and 95% confidence intervals (CIs) estimated. Sensitivity analyses varied lag periods, follow-up durations, analytical frameworks, and matching strategies, while subgroup analyses examined age, sex, race, BMI, and diabetes status. The study complied with the Declaration of Helsinki and received IRB exemption (#11312-E01 and #11212-E02). After matching, well-balanced cohorts were achieved across comparisons. Tirzepatide use was associated with a significantly lower risk of CTS compared with GLP-1RAs (HR 0.82; 95% CI 0.71-0.95), with no significant difference in CTS surgery. In comparison with other anti-obesity medications, tirzepatide was associated with reduced risks of both CTS (HR 0.75; 95% CI 0.65-0.85) and CTS surgery (HR 0.64; 95% CI 0.44-0.94). In conclusion, Tirzepatide use was associated with reduced risks of CTS, particularly when compared with non-GLP-1RA therapies, suggesting potential metabolic and neuroprotective benefits.
