A provider-focused briefing on adalimumab availability, biosimilar landscape, formulary shifts, and practical tools for ensuring patient access in 2026.
Adalimumab remains one of the most frequently prescribed biologic medications in the United States, with indications spanning rheumatology, gastroenterology, dermatology, and ophthalmology. While the entry of more than 10 biosimilars since 2023 has expanded the supply landscape, it has also introduced new complexities for prescribers navigating formulary changes, interchangeability designations, and patient access barriers.
This briefing covers the current state of adalimumab availability, what's changed, and practical steps your practice can take to minimize treatment disruptions for your patients.
Understanding the current landscape requires context:
The biosimilar transition has meaningful implications for how you prescribe and manage adalimumab therapy:
As of 2026, seven adalimumab biosimilars have FDA interchangeable designations: Amjevita, Cyltezo, Hadlima, Hyrimoz, Hulio, Simlandi, and Yuflyma. In most states, pharmacists can substitute an interchangeable biosimilar for the prescribed product without prescriber notification — similar to generic substitution. State laws vary on notification requirements.
Clinical implication: Your patients may receive a different adalimumab product than what you prescribed. Consider discussing this possibility proactively with patients to avoid confusion and ensure adherence.
Insurance-driven formulary changes may require stable patients to switch from one adalimumab product to another mid-treatment. While clinical data supports the safety of switching between biosimilars, the administrative burden falls on your practice when new prior authorizations are needed.
When writing prescriptions, consider whether to specify a product name or write for "adalimumab" generically. Specifying a product may help ensure your patient gets the version you intend, but may create access issues if that product isn't on formulary. Writing generically allows pharmacy flexibility but less prescriber control. There is no single right answer — it depends on your patient's insurance and clinical situation.
Adalimumab is not on the FDA or ASHP drug shortage lists as of early 2026. Supply is robust across multiple manufacturers. However, localized access issues persist due to:
The biosimilar wave has begun to move the needle on pricing:
Net costs to payers are significantly lower due to rebates, but patient out-of-pocket costs depend heavily on plan design. Patients on high-deductible plans or without insurance may face the full list price.
Key development: Some payers (e.g., Blue Shield of California) have partnered with biosimilar manufacturers to offer $0 out-of-pocket costs for members, a model that may expand in 2026.

The adalimumab biosimilar market is maturing. Key trends to watch in 2026 and beyond:
Adalimumab availability in 2026 is fundamentally a navigation problem, not a supply problem. The medication exists in abundance across multiple manufacturers. The challenge lies in matching patients to the right product, at the right price, through the right pharmacy channel, with the right insurance authorization.
Your practice can reduce patient disruptions by staying current on formulary preferences, proactively discussing biosimilar switching with patients, and leveraging tools like Medfinder for providers to support real-time decision-making.
