Overview
What is this medicine?
How to Use This Medicine
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 selecting an injection site, avoid areas within 2 inches (5 cm) of the belly button and 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.

Precautions & Cautions
As this drug may increase your risk of developing an infection, it is crucial to practice good hygiene by washing your hands frequently and avoiding close contact with individuals who have infections, colds, or flu.
If you have a history of hepatitis B or are a carrier of the virus, consult your doctor, as medications like this one can cause the virus to reactivate, potentially leading to severe and life-threatening liver problems. Your doctor will likely recommend hepatitis B testing, and it is vital to follow their instructions.
Before starting treatment with this medication, ensure you are up to date with all recommended vaccinations. However, consult your doctor before receiving any vaccines, as some may not be effective or may increase the risk of infection when used in conjunction with this drug.
Avoid receiving live or weakened bacteria vaccines, such as BCG for bladder cancer, while taking this medication, and discuss any concerns with your doctor.
Regular blood tests and other laboratory evaluations are necessary to monitor your health while taking this medication. Adhere to the schedule recommended by your doctor.
Be aware that this drug may cause high cholesterol levels. If you have concerns or questions, discuss them with your doctor.
If you have a latex allergy, inform your doctor, as some products may contain latex.
In the event of sunburn or other skin problems, consult your doctor. Additionally, schedule regular skin checks and report any changes, such as new warts, skin sores, or reddish bumps that bleed or do not heal, or changes in the color or size of moles, to your doctor.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects.
If you are pregnant, plan to become pregnant, or are breastfeeding, discuss the potential benefits and risks of this medication with your doctor. If you used this drug during pregnancy, inform your baby's doctor, as you will need to discuss the safety and timing of certain vaccinations.
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 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. Call 1-800-222-1222 (Poison Control Center) for further guidance.
Drug Interactions
Contraindicated Interactions
- Live vaccines (during adalimumab treatment)
Major Interactions
- Other TNF blockers (e.g., etanercept, infliximab, golimumab, certolizumab pegol) - increased risk of serious infection.
- Anakinra - increased risk of serious infection and neutropenia.
- Abatacept - increased risk of serious infection.
Moderate Interactions
- Immunosuppressants (e.g., methotrexate, corticosteroids, azathioprine, 6-mercaptopurine) - increased risk of infection (often used concomitantly, but requires careful monitoring).
- Vaccines (non-live) - may result in a diminished immune response.
Monitoring
Baseline Monitoring
Rationale: To rule out active or latent TB infection before initiating treatment, as TNF blockers can reactivate latent TB.
Timing: Before initiating therapy.
Rationale: To rule out active or latent HBV infection, as TNF blockers can reactivate HBV.
Timing: Before initiating therapy.
Rationale: To establish baseline hematologic parameters and monitor for cytopenias.
Timing: Before initiating therapy.
Rationale: To establish baseline liver function and monitor for drug-induced liver injury.
Timing: Before initiating therapy.
Routine Monitoring
Frequency: Regularly throughout therapy and for several months after discontinuation.
Target: Absence of new or worsening signs/symptoms of infection.
Action Threshold: Prompt evaluation and potential discontinuation of adalimumab if serious infection develops.
Frequency: Periodically, or as clinically indicated.
Target: Within normal limits.
Action Threshold: Investigate persistent cytopenias; consider discontinuation if clinically significant.
Frequency: Periodically, or as clinically indicated.
Target: Within normal limits.
Action Threshold: Investigate persistent elevations; consider discontinuation if clinically significant.
Frequency: Regularly throughout therapy.
Target: Absence of new or worsening signs/symptoms of malignancy.
Action Threshold: Prompt evaluation and appropriate management.

Special Patient Groups
Pregnancy
Adalimumab crosses the placenta, particularly during the third trimester. Use during pregnancy only if clearly needed and the potential benefit justifies the potential risk to the fetus. Infants exposed to adalimumab in utero may be at increased risk of infection; avoid administration of live vaccines to these infants for 6 months after the mother's last dose during pregnancy.
Trimester-Specific Risks:
Lactation
Adalimumab is present in human milk at low concentrations. The amount ingested by a breastfed infant is very low. Given the large molecular weight, absorption by the infant is unlikely. Generally considered compatible with breastfeeding.
Pediatric Use
Approved for several pediatric indications including Juvenile Idiopathic Arthritis (JIA), Crohn's Disease, Plaque Psoriasis, and Uveitis. Dosing is weight-based. Increased risk of malignancies (e.g., lymphoma) has been reported in children and adolescents treated with TNF blockers.
Geriatric Use
Increased incidence of serious infections and malignancies has been observed in patients 65 years of age and older treated with TNF blockers. Use with caution and monitor closely for infections and malignancies.
Clinical Information
Clinical Pearls
- Amjevita is a biosimilar to Humira, offering a similar efficacy and safety profile.
- Patients must be screened for active and latent tuberculosis (TB) and hepatitis B virus (HBV) infection prior to initiating therapy.
- Live vaccines should not be administered concurrently with adalimumab. Patients should be up-to-date on all immunizations prior to starting therapy.
- Monitor patients closely for signs and symptoms of serious infections, including opportunistic infections, during and after treatment.
- Rare cases of new or worsening heart failure, demyelinating disease (e.g., multiple sclerosis), and lupus-like syndrome have been reported.
- Patients should be educated on proper subcutaneous injection technique and rotation of injection sites.
Alternative Therapies
- Other TNF-alpha inhibitors (e.g., etanercept, infliximab, golimumab, certolizumab pegol)
- Other biologics with different mechanisms of action (e.g., ustekinumab, secukinumab, ixekizumab, risankizumab, guselkumab, tofacitinib, upadacitinib, baricitinib, abatacept, rituximab, vedolizumab, natalizumab)
- Conventional synthetic DMARDs (e.g., methotrexate, sulfasalazine, hydroxychloroquine, leflunomide)
- Corticosteroids
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
