The use of injected medications in the United States has significantly increased over the past five years. In the 1990s, the number of adults taking five or more prescription drugs doubled, and now, in the 2020s, injections have become more common. As of 2025, approximately 12% of U.S. adults were using injected medications, with GLP-1 shots accounting for about 7% of all prescriptions. The rise in usage includes treatments for diabetes, weight loss, and cosmetic procedures such as Botox and fillers, with millions of injections administered annually.
The trend towards injections began gaining momentum with the FDA's approval of semaglutide, the active ingredient in Ozempic, for obesity treatment in 2021. This led to increased interest in various peptide injections, which have been promoted by public figures and health officials. Despite a natural fear of needles, a large number of Americans have participated in the largest mass injection effort in history, particularly during the COVID-19 vaccination campaign, where over half a billion doses were administered by the end of 2021.
Concerns about vaccine hesitancy related to needle fear persist, but the cultural acceptance of injections has grown. Some individuals express a preference for injections over oral medications, viewing them as more effective. This shift reflects a broader trend towards personal responsibility in health care, with individuals increasingly seeking to optimize their health through various injection-based treatments.
