Overview
What is this medicine?
How to Use This Medicine
To ensure safe and effective use, follow your doctor's instructions and read all accompanying information carefully. 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 particulate matter. The solution should be colorless to faintly yellow; do not use it if the color has changed.
When selecting an injection site, avoid areas within 2 inches (5 cm) of the belly button, as well as skin that is irritated, tender, bruised, red, scaly, hard, scarred, or has stretch marks. Rotate the injection site with each use to minimize the risk of skin reactions.
To reduce discomfort during injection, 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 avoid heating the medication. After use, discard the device and do not reuse it. Dispose of needles and other sharp objects in a designated container, and follow local regulations for disposing of full containers.
If you accidentally drop the device, consult the package insert or speak with your doctor or pharmacist to determine whether it can still be used. If you have any questions or concerns, do not hesitate to reach out to your healthcare provider.

If you used this medication during pregnancy, inform your baby's doctor to discuss the safety and timing of certain vaccines.
Overdose Information
Overdose Symptoms:
- No specific symptoms of overdose have been identified in clinical trials. Doses up to 10 mg/kg (approximately 700 mg) have been administered intravenously without dose-limiting toxicity.
What to Do:
In case of overdose, it is recommended that the patient be monitored for any signs or symptoms of adverse reactions or effects and appropriate symptomatic treatment instituted immediately. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Contraindicated Interactions
- Live vaccines (concurrent administration)
Major Interactions
- Anakinra (increased risk of serious infection and neutropenia)
- Abatacept (increased risk of serious infection)
- Other TNF blockers (e.g., etanercept, infliximab, certolizumab, golimumab) (increased risk of serious infection)
- Immunosuppressants (e.g., azathioprine, 6-mercaptopurine, methotrexate) (increased risk of myelosuppression and serious infection when used concurrently, especially in Crohn's disease)
Moderate Interactions
- Vaccines (may reduce immune response to inactivated vaccines)
Monitoring
Baseline Monitoring
Rationale: To rule out latent or active TB infection before initiating therapy, as TNF blockers can reactivate latent TB.
Timing: Prior to initiation of therapy
Rationale: To rule out active or latent HBV infection, as TNF blockers can reactivate HBV.
Timing: Prior to initiation of therapy
Rationale: To assess baseline hematologic parameters, as cytopenias can occur.
Timing: Prior to initiation of therapy
Rationale: To assess baseline liver function, as liver enzyme elevations can occur.
Timing: Prior to initiation of therapy
Rationale: To establish a baseline for monitoring therapeutic response.
Timing: Prior to initiation of therapy
Routine Monitoring
Frequency: At each visit and ongoing patient self-monitoring
Target: Absence of infection
Action Threshold: Prompt evaluation and treatment if infection suspected; consider temporary discontinuation of adalimumab.
Frequency: At each visit and ongoing patient self-monitoring
Target: Absence of malignancy
Action Threshold: Prompt evaluation if malignancy suspected.
Frequency: Periodically (e.g., every 3-6 months or as clinically indicated)

Frequency: Periodically (e.g., every 3-6 months or as clinically indicated)
Target: Within normal limits or stable
Action Threshold: Investigate persistent elevations; consider discontinuation if clinically significant.
Frequency: Every 3-6 months or as clinically indicated

Symptom Monitoring
- Signs of serious infection (e.g., persistent fever, chills, cough, shortness of breath, skin lesions, diarrhea, dysuria)
- Signs of allergic reaction (e.g., rash, hives, swelling of face/lips/tongue, difficulty breathing)
- Signs of new or worsening heart failure (e.g., shortness of breath, swelling of ankles/feet)
- Signs of demyelinating disease (e.g., numbness, tingling, weakness, vision changes)
- Signs of lupus-like syndrome (e.g., joint pain, rash on cheeks/arms, fever)

- Signs of liver injury (e.g., jaundice, dark urine, abdominal pain, fatigue)
Special Patient Groups
Pregnancy
Adalimumab is an IgG1 antibody and is known to cross the placenta, especially during the third trimester. While human data suggest that adalimumab does not increase the risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes, exposure during the third trimester may lead to detectable serum concentrations in the infant for several months after birth. Live vaccines should not be administered to infants exposed to adalimumab in utero until their serum adalimumab levels are undetectable or for at least 6 months after birth.
Trimester-Specific Risks:
Lactation
Adalimumab is present in human milk at low levels. The effects of local gastrointestinal exposure and systemic exposure in the breastfed infant are unknown. However, due to the large molecular weight, absorption by the infant is likely to be minimal. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for adalimumab and any potential adverse effects on the breastfed infant from adalimumab or from the underlying maternal condition. Generally considered compatible with breastfeeding.
Pediatric Use
Approved for various pediatric indications including Juvenile Idiopathic Arthritis (JIA) in patients 2 years and older, Crohn's Disease in patients 6 years and older, Plaque Psoriasis in patients 4 years and older, and Uveitis in patients 2 years and older. Dosing is weight-based for many indications. Increased risk of malignancy (lymphoma) has been reported in children and adolescents treated with TNF blockers.
Geriatric Use
No overall differences in safety or effectiveness were observed between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Use with caution due to the generally higher incidence of infections in the elderly population.
Clinical Information
Clinical Pearls
- Amjevita is a biosimilar to Humira. Ensure patients understand it is a different product but with the same active ingredient and mechanism of action.
- Always screen for latent TB and HBV before initiating therapy and monitor for reactivation during treatment.
- Educate patients on proper subcutaneous injection technique and storage (refrigeration, protect from light).
- Emphasize the importance of reporting any signs of infection immediately.
- Patients should carry an alert card indicating they are on a TNF blocker.
- Consider temporary discontinuation of adalimumab if a patient develops a serious infection.
- Monitor for new or worsening symptoms of heart failure, demyelinating disease, or lupus-like syndrome.
- Live vaccines are contraindicated; inactivated vaccines may be given but may have a reduced response.
Alternative Therapies
- Other TNF-alpha inhibitors (e.g., infliximab, etanercept, golimumab, certolizumab pegol)
- Other biologics with different mechanisms of action (e.g., abatacept, rituximab, tocilizumab, ustekinumab, secukinumab, ixekizumab, guselkumab, risankizumab, upadacitinib, tofacitinib)
- Conventional DMARDs (e.g., methotrexate, sulfasalazine, hydroxychloroquine, leflunomide)
- Corticosteroids
- NSAIDs
