Intravenous (IV) solution manufacturers have a critical role in healthcare delivery, supplying essential fluids like saline and dextrose used in virtually every care setting, from hospitals and surgical centers to outpatient infusion clinics. Historically, demand has remained stable and predictable, linked closely to procedure volumes and inpatient utilization. However, over the past five years, demand has accelerated because of a shift toward outpatient care, the rise of home infusions and growth in chronic disease management. The expansion of ambulatory surgery centers (ASCs) and non-hospital care sites has also created new, decentralized demand for IV fluids, increasing the number of delivery points. Despite being a commoditized product, IV solutions are volume-driven and critical to day-to-day patient care, which places pressure on manufacturers to deliver a consistent supply at a low price. The rising purchasing power of group purchasing organizations (GPOs) has intensified price competition among manufacturers, pushing prices lower and making it challenging for suppliers to invest in new capacity or product innovation. In all, revenue has risen at a CAGR of 0.2% to an estimated $3.4 billion over the past five years, including expected growth of 3.2% in 2025. In 2024, the industry’s vulnerability was exposed when Hurricane Helene severely disrupted Baxter’s North Cove facility in North Carolina, the single largest US producer, with this single facility accounting for roughly 60% of the national IV fluid supply. The flooding led to an immediate nationwide shortage, forcing hospitals to ration fluids and scramble for backup suppliers. The event highlighted the pitfalls of a highly concentrated industry where a handful of facilities produce nearly all the domestic supply. While competitors like B. Braun ramped up output and FEMA authorized emergency imports, the shortage underscored how disruptions have system-wide effects. The disruption at Baxter’s North Cove facility caused its market share to drop as hospitals and GPOs shifted orders to competitors like B. Braun and imports. This event pushed health systems and buyers to diversify their supplier base, weakening reliance on any single manufacturer and potentially prompting a long-term shift in market dynamics. IV solution manufacturing is expected to grow moderately, driven by outpatient expansion, aging demographics and increased chronic care treatment. However, growth will be uneven across settings: while hospitals remain the largest customers, infusion clinics and home care are driving new demand that requires more nimble packaging and distribution models. Manufacturers will be under pressure to modernize facilities, diversify geographic production and improve risk management capabilities. Long-term, demand will continue rising, but aggressive GPO pricing, high regulatory costs and the commoditized nature of the product will constrain profit. New competitors, including a Saudi-based IV production facility (announced in May 2025 in Trump’s Saudi-US economic partnership), could introduce headwinds too. Investments in automation and efficiency will be essential for manufacturers to remain competitive, control costs and maintain reliability. Revenue will expand moving forward, increasing at a CAGR of 2.3% to an estimated $3.9 billion over the next five years.
