The landscape of medication availability in the United States is frequently disrupted by persistent shortages. While the number of active drug shortages saw a slight decrease toward the end of 2024 from a record high earlier in the year, the problem remains significant and poses ongoing challenges to patient care. These shortages affect a wide array of treatments, from lifesaving oncology drugs to everyday antibiotics, requiring careful management by healthcare professionals and constant vigilance from patients.
Specific Drug Categories Facing Shortages
Shortages are not limited to one type of medication but rather impact diverse therapeutic areas. The following categories represent some of the most consistently affected drug classes, based on reports from the FDA and ASHP.
Oncology Medications
Generic injectable chemotherapy drugs have been a source of significant concern for years. The impact on cancer patients is particularly severe, as these shortages can force treatment delays or the use of less effective alternatives, with potentially devastating consequences.
- Methotrexate Sodium Injection: An essential chemotherapy agent, this remains on the shortage list, with availability affected by high demand and manufacturing issues.
- Carboplatin Injection: While supply has reportedly improved at some health systems since extreme shortages in 2023, the drug is still listed in shortage and manufacturing delays persist.
- Cisplatin Injection: Similar to carboplatin, the shortage of this crucial drug has caused widespread issues but has seen recent improvements in supply.
Sterile Injectables and Hospital Supplies
Many of the most critical shortages involve sterile injectable medications, which are essential for hospital emergency rooms, surgeries, and intensive care units. The complex, low-margin manufacturing process for these generics makes them especially vulnerable to disruptions.
- IV Fluids (e.g., Sodium Chloride, Dextrose): Shortages of these fundamental hospital supplies have been a recurring issue, exacerbated by natural disasters like Hurricane Helene in late 2024, which impacted manufacturing plants.
- Pain Treatments (e.g., Morphine, Fentanyl): Injectable opioids used for pain management continue to face limited availability or high demand from manufacturers.
- Epinephrine Injections: Both auto-injectors and injections have been listed as being in limited supply.
Antibiotics and Antimicrobials
Shortages in this category can lead to treatment delays or the use of broader-spectrum antibiotics, contributing to the growing problem of antibiotic resistance.
- Antimicrobials: A wide range of antimicrobials, including antibiotics, are regularly featured on shortage lists, requiring clinicians to find alternative therapies.
- Fluconazole Injection: This antifungal medication is among those with limited availability.
- Acetazolamide Injection: This medication was recently added to the ASHP shortage list in September 2025.
Central Nervous System (CNS) Drugs
This category includes medications for conditions like ADHD and anxiety, where demand has often outpaced supply due to various factors, including manufacturing delays and increased use.
- ADHD Medications: The long-standing shortage affecting amphetamine mixed salts (e.g., Adderall) and lisdexamfetamine (Vyvanse) continues, with some manufacturers reporting delays and others facing intermittent supply issues as of late 2025.
- Clonazepam Oral Tablets: Used for anxiety and seizures, this medication has also been reported as being in shortage.
Diabetes Medications
While some high-profile diabetes drug shortages have recently been resolved, it is important to note the fluctuating availability that has defined this category.
- GLP-1 Agonists (e.g., Ozempic, Wegovy): Following an extended period of high demand-driven shortages, the FDA declared this shortage resolved in early 2025. As a result, compounded versions are no longer permitted, requiring patients to transition back to the brand-name products.
- Insulin: Recent shortages have affected products like insulin lispro (Humalog) and insulin aspart (Fiasp, NovoLog), though manufacturers like Lilly and Novo Nordisk have made efforts to improve supply.
Root Causes Behind the Shortage Crisis
The pharmaceutical supply chain is a complex global network, and its fragility contributes to chronic and acute drug shortages. Multiple factors, often interacting, are at the root of the problem.
- Manufacturing and Quality Issues: The primary cause of shortages is often linked to production problems at manufacturing facilities, particularly for sterile injectable generics. FDA inspections can uncover quality lapses, leading to shutdowns that disrupt the entire supply chain.
- Raw Material and Supply Chain Problems: The global nature of drug manufacturing means that issues with raw material sourcing, often concentrated in a few countries, can have widespread ripple effects. Geopolitical events, natural disasters, and distribution delays can all disrupt the flow of ingredients and finished products.
- Economic Incentives and Business Decisions: Many generic sterile injectable drugs are low-margin products. Some manufacturers may choose to discontinue these products to focus on more profitable ones, or they may operate production lines at full capacity with little to no redundancy, increasing vulnerability.
- Regulatory and Demand Factors: High demand, such as seen with GLP-1 agonists and ADHD medications, can outpace manufacturing capacity, triggering shortages. In some cases, regulatory quotas, such as those set by the DEA for controlled substances like ADHD drugs, can also constrain supply.
The Fallout: How Shortages Affect Care
The ripple effects of drug shortages extend far beyond a pharmacy's inventory count, significantly compromising patient care and increasing costs across the healthcare system.
- Delayed or Canceled Treatment: For life-threatening conditions like cancer, delays in receiving crucial chemotherapy can be a matter of life or death, as highlighted by stories shared with Congress. For other conditions, delays can lead to disease progression and increased suffering.
- Medication Errors and Adverse Events: When standard medications are unavailable, healthcare providers must use alternative therapies that may be less familiar. This can lead to dosing errors, unexpected side effects, and suboptimal patient outcomes, sometimes with increased toxicity.
- Increased Costs: Shortages increase institutional costs, as health systems must spend more on expensive alternatives or dedicate staff time to managing the crisis. Patients can also face higher out-of-pocket expenses.
- Increased Patient Burden and Anxiety: Patients are often left scrambling to find their prescriptions by calling multiple pharmacies or traveling longer distances. The uncertainty surrounding their treatment can cause significant stress and anxiety.

- Implement Clinical Guidelines: Create and communicate clear guidelines for therapeutic interchanges (switching to a different drug in the same class) or alternative routes of administration when a shortage occurs.
What Patients Can Do
- Communicate with Your Provider: Discuss potential treatment changes or alternatives with your doctor, especially if your current medication is listed in shortage.
- Contact Your Pharmacist: Pharmacists are often the first to know about local availability issues and can provide guidance on finding a pharmacy with stock or coordinating a therapeutic substitution.
- Refill Early (When Possible): Where appropriate and allowed, getting refills slightly earlier can help manage supply, but avoid stockpiling, which can worsen shortages for others.
- Check Official Resources: Patients can also use the FDA and ASHP websites to stay informed about the status of their medications.
Conclusion
The ongoing crisis of drug shortages in the USA is a multifaceted problem with deep roots in manufacturing, supply chain, and economic factors. While official sources track the situation and specific shortages may resolve, the underlying vulnerabilities in the system persist. From critical sterile injectables and chemotherapy to common CNS drugs and fluids, the list of affected medications changes constantly, forcing both patients and healthcare providers to remain adaptable and proactive. Addressing this systemic challenge requires continued attention from policymakers, manufacturers, and the healthcare community to build a more resilient and transparent supply chain for essential medicines.
