How to Use This Medicine

Proper Use of This Medication

To use this medication correctly, follow your doctor's instructions and read all the information provided. This medication is administered via injection into the fatty tissue of the skin, typically on the top of the thigh or in the belly area. If you will be self-administering the injection, your doctor or nurse will provide guidance on the proper technique.

Before and after handling the medication, wash your hands thoroughly. Do not shake the solution, and inspect it for any signs of cloudiness, leakage, or particles. The solution should be colorless to faintly yellow; do not use it if the color has changed.

When administering the injection, avoid areas within 2 inches (5 cm) of the belly button and do not inject into skin that is irritated, tender, bruised, red, scaly, hard, scarred, or has stretch marks. Rotate the injection site with each use to minimize discomfort and reduce the risk of skin reactions.

To make the injection more comfortable, remove the medication from the refrigerator and let it sit at room temperature for up to 30 minutes before use. Do not remove the cap or cover, and do not heat the medication. After use, dispose of the device properly and do not reuse it. Discard needles in a designated needle/sharp disposal box, and follow local regulations for disposing of the box when it is full.

If you have any questions or concerns, consult your doctor or pharmacist. If you accidentally drop the device, check the package insert to determine if it can still be used or if you need to replace it.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Adalimumab is a recombinant human IgG1 monoclonal antibody that specifically binds to human tumor necrosis factor (TNF) alpha and neutralizes its biological function by blocking its interaction with the p55 and p75 cell surface TNF receptors. TNF is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Elevated levels of TNF are found in the synovial fluid of patients with rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis, and in the lesions of patients with plaque psoriasis and hidradenitis suppurativa. Adalimumab also lyses surface TNF-expressing cells in vitro in the presence of complement.

Safety & Warnings

âš ī¸

BLACK BOX WARNING

SERIOUS INFECTIONS: Patients treated with adalimumab are at increased risk for developing serious infections that may lead to hospitalization or death. These infections include tuberculosis (TB), bacterial sepsis, invasive fungal infections (e.g., histoplasmosis, coccidioidomycosis, candidiasis), and other opportunistic infections. Evaluate patients for TB risk factors and test for latent infection prior to and during therapy. Discontinue adalimumab if a serious infection or sepsis develops. MALIGNANCY: Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, including adalimumab. Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare, aggressive, and fatal form of lymphoma, have been reported in adolescents and young adults treated with TNF blockers, including adalimumab, for Crohn's disease or ulcerative colitis. The majority of reported cases occurred in patients treated with azathioprine or 6-mercaptopurine concomitantly with a TNF blocker.

Special Patient Groups

🤰

Pregnancy

Adalimumab is an IgG1 antibody and is known to cross the placenta, especially during the third trimester. Available data from clinical trials and postmarketing experience with adalimumab use in pregnant women have not established an association between adalimumab and major birth defects, miscarriage, or adverse maternal or fetal outcomes. However, live vaccines should be avoided in infants exposed to adalimumab in utero for at least 6 months following the mother's last dose during pregnancy.

Trimester-Specific Risks:

First Trimester: Limited data, but no clear evidence of increased risk of major birth defects.
Second Trimester: Limited data, but no clear evidence of increased risk of major birth defects.
Third Trimester: Significant placental transfer occurs, leading to detectable levels in the infant. Avoid live vaccines in exposed infants for at least 6 months.
🤱

Lactation

Adalimumab is present in human milk. Published data suggest that infant exposure to adalimumab through breast milk is low. The effects of local gastrointestinal exposure and systemic exposure in the breastfed infant are unknown. Consider the benefits of breastfeeding along with the mother's clinical need for Amjevita and any potential adverse effects on the breastfed infant from Amjevita or from the underlying maternal condition.

Infant Risk: Low systemic exposure in infant due to degradation in GI tract; generally considered compatible with breastfeeding, but monitor infant for signs of infection.
đŸ‘ļ

Pediatric Use

Approved for various pediatric indications including Juvenile Idiopathic Arthritis (JIA), Crohn's Disease, Ulcerative Colitis, Plaque Psoriasis, Hidradenitis Suppurativa, and Uveitis. Dosing is weight-based. Increased risk of malignancy (lymphoma, including hepatosplenic T-cell lymphoma) has been reported in children and adolescents treated with TNF blockers.

👴

Geriatric Use

No overall differences in effectiveness or safety were observed between elderly and younger patients, but a higher incidence of serious infections has been observed in patients 65 years of age and older. Use with caution and monitor closely for infections.

Clinical Information

💎

Clinical Pearls

  • Amjevita is a biosimilar to Humira (adalimumab). Biosimilars are highly similar to the reference product with no clinically meaningful differences in terms of safety, purity, and potency.
  • Patients should be thoroughly screened for tuberculosis (latent and active) and hepatitis B virus prior to initiating therapy due to the risk of reactivation.
  • Patients should be educated on the signs and symptoms of serious infections and instructed to seek immediate medical attention if they occur.
  • Injection site reactions (pain, redness, swelling, itching) are common but usually mild and transient. Proper injection technique can help minimize these.
  • Adalimumab can be used as monotherapy or in combination with methotrexate or other non-biologic DMARDs, depending on the indication.
  • Due to its immunosuppressive effects, patients should avoid live vaccines during treatment and for a period after discontinuation.
🔄

Alternative Therapies

  • Other TNF-alpha inhibitors (e.g., etanercept, infliximab, golimumab, certolizumab pegol)
  • Other biologic DMARDs with different mechanisms of action (e.g., abatacept, rituximab, tocilizumab, ustekinumab, secukinumab, ixekizumab, guselkumab, risankizumab, tildrakizumab)
  • Janus Kinase (JAK) inhibitors (e.g., tofacitinib, baricitinib, upadacitinib)
  • Conventional synthetic DMARDs (e.g., methotrexate, sulfasalazine, hydroxychloroquine, leflunomide)
  • Corticosteroids (for acute flares, not long-term maintenance)
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) (for symptomatic relief)
