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 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.
Storage and Disposal

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 allergic reaction and its symptoms.
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 precaution 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, prior to receiving any vaccines during treatment, consult your doctor. The use of certain vaccines in conjunction with this drug may increase the risk of infection or reduce the vaccine's effectiveness.
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 instructed by your doctor.
Be aware that high cholesterol has been reported in patients taking this medication. If you have concerns, 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 examine 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 vaccinations.

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:
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.
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)
