Segmentation Analysis – Breaking Down the Market Dynamics

By Type

In 2024, disposable autoinjectors dominated the market, valued at nearly US$ 6.8 billion. Their widespread acceptance is driven by affordability, convenience, and regulatory preference for single-use devices to reduce contamination risks. Reusable autoinjectors, valued at around US$ 3.6 billion, are gaining momentum with eco-conscious consumers and biologic therapies requiring frequent dosing. The growth of reusable models is bolstered by digital health integration, allowing dose tracking and patient monitoring.

By Technology

Manual autoinjectors retained the largest share in 2024, generating revenues of US$ 6.1 billion, thanks to their cost-effectiveness and wide availability. However, automated autoinjectors are expanding rapidly, valued at US$ 4.2 billion, and projected to grow at the fastest CAGR. These devices, equipped with sensors, spring mechanisms, and smart connectivity, reduce injection errors and improve patient adherence. Their adoption is particularly strong in developed markets where technology integration in healthcare is advancing quickly.

By Route of Administration

Subcutaneous injections represented the largest market in 2024, accounting for nearly 60% of total revenues (US$ 6.2 billion), as most biologics for autoimmune diseases and diabetes are administered through this route. Intramuscular injections contributed around US$ 2.8 billion, primarily driven by vaccines and emergency treatments. Intravenous autoinjectors remain a smaller but emerging category, valued at approximately US$ 1.3 billion, with growing R&D interest in advanced drug formulations that could expand this route.

By Therapy

Therapies for rheumatoid arthritis and other autoimmune conditions dominated the autoinjectors market in 2024, valued at over US$ 3.7 billion, fueled by biologic therapies like TNF inhibitors. Diabetes care accounted for US$ 2.6 billion, with strong adoption of insulin autoinjectors. Multiple sclerosis treatments contributed around US$ 1.9 billion, supported by expanding biologic pipelines. Anaphylaxis management held a steady share of US$ 1.2 billion, anchored by the widespread use of epinephrine autoinjectors. Other therapeutic areas, including oncology and rare diseases, added nearly US$ 1 billion, reflecting the diversification of autoinjector applications.
