Is Amjevita interchangeable with Humira?

Some strengths and dosage forms of Amjevita are interchangeable with Humira, and the pharmacist will not need to get approval from your doctor before they can substitute it for Humira. The Amjevita 10 mg/0.2 mL, 20 mg/0.2 mL and 40 mg/0.2 mL prefilled syringes, and the 40 mg/0.8 mL autoinjector are all interchangeable with Humira.

As of March 2025, approved interchangeable biosimilars for Humira include:

• Abrilada (adalimumab-afzb)
• Amjevita (adalimumab-atto)
• Cyltezo (adalimumab-adbm)
• Hadlima (adalimumab-bwwd)
• Hulio (adalimumab-fkjp)
• Hyrimoz (adalimumab-adaz)
• Simlandi (adalimumab-ryvk)

Additional interchangeable biosimilars for Humira may be approved once reviewed by the FDA.

What is an interchangeable biosimilar?

An interchangeable biosimilar is a biologic product that can automatically be substituted for the reference product (in this case, Humira) by a pharmacist, depending upon state laws. Your pharmacist will not need to contact the doctor to get an approval.

It also means the reference biologic and the new biosimilar can be switched back and forth in a patient without a risk of changes in safety or effectiveness.

This is similar to how generic drugs are routinely substituted for brand-name drugs at the pharmacy. The manufacturer of a biosimilar must submit an application to the Food and Drug Administration (FDA) with enough required information comparing it to the reference product to support an interchangeability status.

Interchangeable products may make it easier for you to access a biologic medicine, because they should be more affordable and more likely to be covered by your insurance. However, these products overall can still be very expensive.

Not all biosimilars are interchangeable. If interchangeable status has not been approved by the FDA for a particular biologic, biosimilars can be dispensed in place of another biological product if the healthcare provider specifically prescribes the biosimilar product by name (and based on state laws).

How do I find out which biosimilars are interchangeable?

FDA-approved biological products that are designated as interchangeable can be found in The Purple Book. Your pharmacist can also tell you which biological products are interchangeable.

The Purple Book is the FDA resource for pharmacists and other health care providers interested in making an interchange between a reference biologic and a biosimilar.

As of March 2025, there are 53 biosimilars approved by the U.S. Food and Drug Administration (FDA), and at least 11 of these are interchangeable.

A proposed biosimilar or interchangeable product is compared to and evaluated against a reference product to ensure that the proposed product is highly similar to, and has no clinically meaningful differences from, its reference product, according to the FDA.

Automatic substitution by a pharmacist can occur once a product is deemed as interchangeable by the FDA. If the product is listed as interchangeable, then it is biosimilar to the reference product and will produce the same clinical result.
