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. Avoid injecting into skin within 2 inches (5 cm) of the belly button or into 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, dispose of the device properly and do not reuse it. Discard needles in a designated sharps disposal container, and follow local regulations for disposing of full containers. If you have any questions or concerns, consult your doctor or pharmacist.

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 instruct you on the necessary hepatitis B testing.
Before starting treatment with this medication, ensure you are up to date with all recommended vaccinations. However, it is vital to discuss your vaccination schedule with your doctor, as some vaccines may not be effective or may increase the risk of infection when used concurrently with this drug.
Do not receive live or weakened bacteria vaccines, such as BCG for bladder cancer, while taking this medication. Consult your doctor for guidance.
Regularly undergo blood tests and other laboratory evaluations as directed by your doctor.
Be aware that this medication may cause high cholesterol levels. If you have concerns or questions, consult 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 examinations and report any new or changing skin lesions, such as warts, sores, or 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, planning to become pregnant, or breastfeeding, discuss the potential benefits and risks of this medication with your doctor. If you used this medication during pregnancy, inform your baby's doctor 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 toxicities.
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 (during treatment)
- Anakinra (Kineret) - increased risk of serious infection and neutropenia
- Abatacept (Orencia) - increased risk of serious infection
Major Interactions
- Other TNF blockers (e.g., etanercept, infliximab, golimumab, certolizumab) - increased risk of serious infection

Moderate Interactions
- Corticosteroids - may increase risk of infection when used concurrently, but often used in combination for disease control
- Warfarin - potential for altered INR (monitor INR)

Special Patient Groups
Pregnancy
Adalimumab is an IgG1 antibody and is known to cross the placenta, especially during the third trimester. Limited data from observational studies and registries suggest no increased risk of major birth defects or miscarriage. However, live vaccines should not be administered to infants exposed to adalimumab in utero for at least 5 months after the mother's last dose during pregnancy.
Trimester-Specific Risks:
Lactation
Adalimumab is present in human milk at low concentrations. Systemic exposure in a breastfed infant is expected to be low because adalimumab is a large protein and is likely to be degraded in the infant's gastrointestinal tract. No adverse effects on breastfed infants have been reported. Considered compatible with breastfeeding by many experts.
Pediatric Use
Safety and efficacy established for specific indications in pediatric patients (e.g., JIA, Crohn's, UC, Plaque Psoriasis, Uveitis). Dosing is weight-based. Increased risk of malignancy (lymphoma, HSTCL) reported in children and adolescents treated with TNF blockers, especially with concomitant immunosuppressants.
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. Increased incidence of serious infections and malignancies in the elderly population in general, so caution is advised.
Clinical Information
Clinical Pearls
- Amjevita is a biosimilar to Humira. Ensure patients understand this and are comfortable with the switch if applicable.
- Patients should be thoroughly screened for latent TB and HBV prior to initiation and monitored during therapy.
- Educate patients on the importance of reporting any signs of infection immediately.
- Advise patients to avoid live vaccines during treatment and for several months after stopping therapy.
- Monitor for signs of new or worsening heart failure, demyelinating disease, and hematologic reactions.
- Consider the increased risk of malignancy, particularly non-melanoma skin cancer and lymphoma, with long-term use.
- Injection site reactions are common but usually mild and transient. Proper injection technique can minimize these.
Alternative Therapies
- Other TNF-alpha inhibitors (e.g., etanercept, infliximab, golimumab, certolizumab pegol)
- Other biologics with different mechanisms of action (e.g., abatacept, rituximab, tocilizumab, ustekinumab, secukinumab, ixekizumab, guselkumab, risankizumab, upadacitinib, tofacitinib)
- Conventional synthetic DMARDs (e.g., methotrexate, sulfasalazine, hydroxychloroquine, leflunomide)
- Corticosteroids
- NSAIDs
