What is driving the growth of the United States Generic Injectables Market?

The United States generic injectables market reached a value of approximately USD 15.07 billion in 2024 and is projected to grow at a compound annual growth rate (CAGR) of 7.00% from 2025 to 2034, potentially reaching around USD 29.64 billion by 2034.
