Nearly three million prescriptions for hydroxychloroquine and ivermectin were issued during the pandemic, despite strong evidence against their efficacy. This UCLA-led study delves into the implications of this trend, highlighting the urgent need for policy reforms to curb misinformation and protect vulnerable communities.

Addressing Misinformation and Protecting Public Health

The Pandemic's Impact on Prescription Trends

During the tumultuous period from January 2020 to June 2023, outpatient prescriptions for hydroxychloroquine and ivermectin saw a dramatic surge, increasing by factors of two to ten compared to pre-pandemic levels. These medications were prescribed primarily as treatments for COVID-19, even though robust scientific evidence refuted their effectiveness. The research, conducted by UCLA, examined insurance claims data from over 8.1 million patients across all 50 states, revealing a staggering $272 million spent on these drugs.The spike in prescriptions was particularly pronounced among older adults, with those aged 65 and above receiving three times more prescriptions than their younger counterparts. Additionally, ivermectin use was notably higher in socially vulnerable neighborhoods, especially in the Southern United States. This geographic variation suggests that factors beyond mere availability influenced prescribing patterns, pointing to deeper societal issues at play.

Economic and Demographic Insights

The economic impact of these prescriptions is significant. Approximately $272 million was allocated to hydroxychloroquine and ivermectin during the study period. Notably, $18 million of this amount was spent after March 2022, when FDA-approved treatments like Paxlovid became available. This expenditure underscores the persistence of non-evidence-based treatments even when effective alternatives existed.Demographically, the study found that prescription rates varied widely. For instance, hydroxychloroquine peaked at 133% of pre-pandemic levels in March 2020, while ivermectin usage surged throughout 2020 and 2021, peaking at over ten times pre-pandemic levels by August 2021. After FDA-approved medications became accessible, the use of these unproven treatments dropped by 93%, indicating a shift towards evidence-based care once viable options were available.

Policy Implications and Future Directions

The findings of this study have profound implications for public health policy. Dr. John Mafi, senior author of the study, emphasized the need for policy reforms to combat misinformation and mistrust in scientific institutions. He proposed eliminating undue industry influence in government, enhancing transparency around scientific uncertainty, and increasing public funding for clinical trials of new drugs as critical steps.Moreover, the study highlights the importance of addressing the root causes of non-evidence-based care, particularly in times of uncertainty and distress. Multilevel efforts are necessary to promote equitable, high-value care while minimizing reliance on ineffective treatments. By understanding the complex drivers behind these trends, policymakers can better protect vulnerable populations and ensure that healthcare resources are used efficiently and effectively.

Challenges and Limitations

While the study provides valuable insights, it also acknowledges certain limitations. The data used came from a "convenience sample," which may not be entirely representative of the broader population. Additionally, medications obtained without insurance or prescriptions were not included in the analysis, potentially underestimating the true scope of the issue. Despite these constraints, the research offers a comprehensive overview of the utilization and spending trends for hydroxychloroquine and ivermectin during the pandemic.
