Idiopathic Intracranial Hypertension Prevalence and Hormonal Contraception

The meta-analysis found no significant association between HC use and IIH prevalence, with consistent results across various HC modalities. This evidence provides confidence to reassure patients with IIH and clinicians that the directed use of HC should be continued as appropriate. The limited quality of available evidence and considerable heterogeneity highlights the necessity for large-scale, well-designed studies, particularly in diverse patient populations, to validate these findings.
