What is Hyrimoz?
Hyrimoz is an FDA-approved medication used to treat various inflammatory conditions. It is specifically designed to reduce the signs and symptoms of several autoimmune diseases by inhibiting the action of TNF, a substance in the body that causes inflammation. The drug is administered subcutaneously and is available in two forms: a Sensoready® pen autoinjector and a prefilled syringe.
Chemical Composition and Formulation
The active ingredient in Hyrimoz is adalimumab-adaz, a monoclonal antibody that binds to TNF-alpha, inhibiting its interaction with the TNF receptor. This mechanism helps in reducing inflammatory responses. The formulation is designed for subcutaneous administration and is intended to be used at regular intervals as prescribed by a healthcare provider.
Hyrimoz is manufactured by Sandoz Inc., a global leader in generic pharmaceuticals and biosimilars. Sandoz is known for its commitment to increasing access to high-quality, affordable biologics.
Primary Indications for Hyrimoz
Hyrimoz is primarily indicated for the treatment of several chronic inflammatory conditions, including:
- Moderate to severe rheumatoid arthritis in adults
- Psoriatic arthritis
- Ankylosing spondylitis
- Moderate to severe Crohn’s disease in adults and children 6 years of age and older
- Moderate to severe ulcerative colitis in adults
- Moderate to severe chronic plaque psoriasis in adults
- Moderate to severe hidradenitis suppurativa in adults
- Non-infectious intermediate, posterior, and panuveitis
Diseases and Conditions it is Prescribed for
In addition to the primary indications, Hyrimoz is also used in children 2 years of age and older for juvenile idiopathic arthritis. It can be used alone or in combination with other medicines like methotrexate, depending on the specific condition being treated.
Off-label Uses (if any)
Currently, there are no widely recognized off-label uses for Hyrimoz. However, as with any medication, it may be prescribed for conditions not listed in the official indications based on the discretion of the healthcare provider.

Mechanism of Action
How Hyrimoz Works in the Body
Hyrimoz, containing the active ingredient adalimumab, is classified as a biological response modifier and a TNF (tumor necrosis factor) blocker. It is specifically designed to target and neutralize TNF-alpha, an inflammatory protein produced in excess in various autoimmune conditions. By blocking TNF-alpha, Hyrimoz effectively reduces inflammation, pain, and cellular damage in affected areas. The time it takes to notice an improvement in symptoms can range from 4 to 12 weeks, depending on the condition being treated.
Its Effect on the Immune System
As a TNF blocker, Hyrimoz plays a significant role in modulating the immune system. TNF-alpha is a key cytokine in the inflammatory process, and its overproduction can lead to the symptoms associated with autoimmune diseases. By inhibiting TNF-alpha, Hyrimoz helps to dampen the overactive immune response, thereby reducing inflammation and its associated symptoms.
Comparison with Similar Drugs
Hyrimoz is a biosimilar to Humira®, another adalimumab product. Biosimilars are highly similar to their reference products in terms of safety, purity, and potency. While Hyrimoz and Humira® share the same mechanism of action, Hyrimoz may be available at a lower cost, offering an alternative for patients seeking treatment with TNF blockers.
Dosage and Administration
Standard Dosing Information
The dosage of Hyrimoz varies depending on the condition being treated. For adults with conditions like rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis, the recommended dose is typically 40 mg administered every other week.
Different Dosages for Specific Conditions
- For Crohn’s disease or ulcerative colitis in adults: An initial dose of 160 mg, followed by 80 mg two weeks later, and then 40 mg every second week starting from the fourth week.
- For psoriasis or uveitis in adults: An initial dose of 80 mg, followed by 40 mg every other week starting one week after the first dose.
- For children over 2 years old with uveitis: The dose is based on body weight, with 20 mg every other week for children under 30 kg and 40 mg for those weighing more or equal to 30 kg.
Administration Methods and Guidelines
Hyrimoz is administered via subcutaneous injection, typically in the front of the thigh or abdomen. The medication comes in prefilled syringes or a SensoReady® Pen for ease of use. Patients are usually instructed by a healthcare professional on how to prepare and inject the first dose. It’s crucial to follow the prescribed dosing schedule and not to miss doses for optimal effectiveness.
Common Side Effects
The most common side effects of Hyrimoz include:
- Injection site reactions (redness, itching, pain, or swelling)
- Skin rash
- Upper respiratory infections (like colds or sinus infections)
Rare but Serious Side Effects
Some rare but serious side effects include:
- Abdominal pain
- Breathing difficulty
- Chest pain
- Signs of serious infections (fever, chills, severe diarrhea)
- Signs of liver problems (yellowing of the skin or eyes, dark urine)
- Symptoms of pneumonia (fever, shortness of breath, fatigue)
Long-term Side Effects
Long-term use of Hyrimoz may increase the risk of certain conditions such as lymphoma or other cancers, particularly in children and adolescents. It’s important to discuss the potential risks and benefits of long-term treatment with Hyrimoz with a healthcare provider.
