Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the symptoms you experienced.
If you are currently taking abatacept or anakinra, as these medications may interact with this drug.
If you are using another medication similar to this one. If you are unsure, consult your doctor or pharmacist to determine the best course of action.
Please note that this is not an exhaustive list of all potential interactions. To ensure your safety, it is crucial to disclose all of your medications, including:
Prescription and over-the-counter (OTC) medications
Natural products
Vitamins
Additionally, inform your doctor about any existing health problems. This information will help your doctor determine whether it is safe for you to take this medication in conjunction with your other medications and health conditions.
Remember, do not start, stop, or change the dosage of any medication without first consulting your doctor. This will help prevent potential interactions and ensure your safety while taking this medication.
Precautions & Cautions
While taking this drug, you may be more susceptible to infections. To minimize this risk, practice good hygiene by washing your hands frequently and avoid 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. Medications like this one can cause the hepatitis B virus to reactivate, potentially leading to severe and life-threatening liver problems. As directed by your doctor, undergo hepatitis B testing and discuss any concerns with your healthcare provider.
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 vaccines 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. Discuss any vaccine-related concerns with your doctor.
Regularly undergo blood tests and other laboratory evaluations as instructed by your doctor.
Be aware that this medication may cause high cholesterol. 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. Regularly inspect your skin and report any changes, such as new warts, skin sores, 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, exercise caution when taking this medication, as you may be more prone to side effects.
If you are pregnant, plan to become pregnant, or are breastfeeding, discuss the benefits and risks of this medication with your doctor. Additionally, if you took 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 due to the nature of the drug. Doses up to 10 mg/kg have been administered without dose-limiting toxicity.
What to Do:
In case of suspected overdose, contact a poison control center or emergency medical services immediately. Provide supportive care and monitor for any adverse reactions. Call 1-800-222-1222 for poison control.
Drug Interactions
Contraindicated Interactions
- Live vaccines (e.g., MMR, varicella, rotavirus, yellow fever, live attenuated influenza vaccine) - due to risk of infection.
Major Interactions
- Anakinra (Kineret) - increased risk of serious infection and neutropenia.
- Abatacept (Orencia) - increased risk of serious infection.
- Other TNF blockers (e.g., etanercept, infliximab) - increased risk of serious infection and no added benefit.
- Immunosuppressants (e.g., azathioprine, 6-mercaptopurine, methotrexate) - increased risk of serious infection when used concomitantly, especially in certain populations (e.g., pediatric CD).
Moderate Interactions
- Warfarin - potential for altered INR; monitor closely.
- Cyclosporine - potential for altered levels; monitor closely.
- Theophylline - potential for altered levels; monitor closely.
Monitoring
Baseline Monitoring
Rationale: To rule out latent or active TB infection, which can be reactivated by TNF blockers.
Timing: Prior to initiation of therapy
Rationale: To rule out active or latent HBV infection, which can be reactivated by TNF blockers.
Timing: Prior to initiation of therapy
Rationale: To assess baseline hematologic status and identify pre-existing cytopenias.
Timing: Prior to initiation of therapy
Rationale: To assess baseline hepatic function.
Timing: Prior to initiation of therapy
Rationale: To ensure patient is free of active infection before starting immunosuppressive therapy.
Timing: Prior to initiation of therapy
Routine Monitoring

Action Threshold: Prompt evaluation and potential discontinuation if serious infection suspected.
Frequency: Periodically (e.g., every 3-6 months or as clinically indicated)

Action Threshold: Significant decrease in cell counts (e.g., persistent neutropenia, thrombocytopenia) may warrant dose reduction or discontinuation.
Frequency: Periodically (e.g., every 3-6 months or as clinically indicated)
Target: Within normal limits
Action Threshold: Significant elevation (e.g., >3x ULN) may warrant further investigation and potential discontinuation.
Frequency: Regularly throughout therapy

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 with adalimumab use during pregnancy. However, due to its immunosuppressive effects, infants exposed to adalimumab in utero may have an increased risk of infection, particularly if live vaccines are administered within 6 months of birth. Discuss risks and benefits with a healthcare provider.
Trimester-Specific Risks:
Lactation
Adalimumab is present in human milk at low levels. Systemic exposure in a breastfed infant is expected to be low because adalimumab is a large protein that is largely degraded in the infant's gastrointestinal tract. No adverse effects on breastfed infants have been reported. Considered compatible with breastfeeding, but monitor infant for signs of infection.
Pediatric Use
Approved for various indications including JIA, CD, UC, PsO, HS, and Uveitis in specific age groups. Increased risk of malignancies, including lymphoma, has been reported in children and adolescents treated with TNF blockers. Careful risk-benefit assessment is crucial.
Geriatric Use
Increased incidence of serious infections (including fatal infections) has been observed in patients 65 years of age and older treated with adalimumab. Use with caution and monitor closely for infections.
Clinical Information
Clinical Pearls
- Prior to initiating Amjevita, thoroughly screen patients for latent or active tuberculosis (TB) and hepatitis B virus (HBV) infection. Treatment for latent TB should be initiated before starting Amjevita.
- Counsel patients extensively on the risk of serious infections and malignancies, and instruct them to report any signs or symptoms of infection immediately.
- Amjevita is a biosimilar to Humira. Ensure patients understand that it is a highly similar and interchangeable product (if designated as such by FDA) with no clinically meaningful differences.
- Patients should avoid live vaccines while on Amjevita and for a period after discontinuation. Consult current guidelines for specific vaccine recommendations.
- Monitor patients for new or worsening symptoms of heart failure or demyelinating disorders, and discontinue Amjevita if these conditions develop.
- The 80mg/0.8ml strength is often used for specific loading doses or maintenance regimens, particularly in conditions like psoriasis or certain phases of Crohn's/ulcerative colitis treatment.
Alternative Therapies
- Other TNF-alpha inhibitors (e.g., Etanercept, Infliximab, Golimumab, Certolizumab pegol)
- Interleukin (IL) inhibitors (e.g., Ustekinumab, Secukinumab, Ixekizumab, Guselkumab, Risankizumab, Tildrakizumab)
- Janus Kinase (JAK) inhibitors (e.g., Tofacitinib, Upadacitinib, Filgotinib)
- Selective T-cell co-stimulation modulators (e.g., Abatacept)
- Selective adhesion molecule inhibitors (e.g., Vedolizumab, Natalizumab)
- Phosphodiesterase 4 (PDE4) inhibitors (e.g., Apremilast)
- Conventional synthetic DMARDs (e.g., Methotrexate, Sulfasalazine, Hydroxychloroquine, Leflunomide)
- Corticosteroids (e.g., Prednisone)
