What is specialty pharmacy?

Specialty pharmacies dispense high-cost and high-touch prescription drugs, which often require special handling. These types of medications include oral drugs, injectables and biologics that treat chronic or complex disease states such as cancer, multiple sclerosis (MS) and rare diseases. Specialty pharmacies may specialize in treating one therapy area or a variety of therapy areas.

Definitive Healthcare tracks more than 3,800 active specialty pharmacies across the U.S. from hundreds of different pharmacy and health system networks. Using data from our SpecialtyRxView product, we share some key insights about the specialty pharmacy market below, including the top therapy areas and how facilities are distributed across the country.

Definitive Healthcare assigns a Primary Therapy Area to a specialty pharmacy based on the therapy area with the highest prescription volume. Specialty pharmacies may serve multiple therapy areas.

What are the most common specialty pharmacy therapy areas?

The bar chart illustrates how specialty pharmacy participation is most concentrated in therapy areas where treatment is both clinically complex and long-term. Oncology leads by a wide margin with 393 specialty pharmacies.

Several chronic, lifelong conditions follow oncology. HIV/AIDS (343), bleeding and blood disorders (322), arthritis (302), and multiple sclerosis (271) are all supported by hundreds of specialty pharmacies, likely indicating sustained demand for treatment. In these therapy areas, success hinges on adherence, persistence, and patient education, which explains why so many specialty pharmacies have invested in supporting ongoing therapy.

Why these therapy areas dominate specialty pharmacy

Generally speaking, the reason why therapy areas such as oncology, HIV/AIDS, and bleeding and blood disorders are the most common therapy areas is because they sit at the intersection of clinical complexity, high cost, and long-term care needs, which are essentially the exact conditions specialty pharmacy was built to support.

Oncology leads in part because modern cancer care is in high demand, high cost, and involves complex therapies. Many oncology therapies are biologics or infusions that require specific handling, dosing, and coordination.

HIV/AIDS dominates because it is a lifelong condition where successful treatment depends strongly on adherence. Some antiretroviral therapies can be expensive, chronic, and sensitive to missed doses or disruptions in access. Specialty pharmacies can add value here by providing ongoing adherence assistance programs, financial support, patient education, and more services.

Finally, bleeding and blood disorders round out the top of the list. These therapies often involve self-administered injectables, individualized dosing, and extremely high per-patient spend. Errors in access, handling, or adherence can have immediate and severe consequences. As a result, specialty pharmacies are critical in patient training, inventory management, payor coordination, and emergency access planning, making them indispensable partners in care delivery.

Where are most specialty pharmacies located in the U.S.?

Distribution of specialty pharmacies

The heatmap shows that specialty pharmacies are highly concentrated in large, populous, and healthcare-dense states, rather than evenly spread across the country. Texas (391), California (370), New York (300), and Florida (302) clearly dominate.

At the other end of the spectrum, rural and low-population states like Wyoming, Alaska, Vermont, the Dakotas, and Montana have very limited specialty pharmacy presence. This doesn’t necessarily indicate lower specialty drug need, but rather that access in these areas is often centralized, regionalized, or mail-based, with patients served by out-of-state specialty pharmacies.

Implications for life sciences and healthcare strategy

Insights into the distribution of specialty pharmacies and which therapy areas are most common can give life sciences companies and healthcare strategists a clearer blueprint for where and how to focus their commercial, access, and engagement efforts.

First, these insights help teams prioritize markets and accounts with the greatest strategic impact. Therapy areas like oncology, HIV/AIDS, and bleeding and blood disorders support large, mature specialty pharmacy networks, signaling where competition, infrastructure, and opportunities already exist. Companies can use this intelligence to identify and prioritize key accounts to engage and to best allocate resources.

Secondly, data on specialty pharmacy concentration helps strategists develop more effective campaigns. For example, in therapy areas with broad participation, success could potentially hinge on differentiation, such as through service models, outcomes data, patient support, and more. In narrower markets, strategy instead shifts toward securing access within those limited networks and building deeper relationships with a smaller pool of specialized partners. These distinctions can result in better planned distribution models and more beneficial contracts.
