ImmunologyBiologicsRheumatology

Drug Class

Anti-TNF-alpha (Tumor Necrosis Factor) Monoclonal Antibody

Pregnancy

Category B — Animal reproduction studies have not demonstrated fetal harm. Adalimumab crosses the placenta, particularly in the third trimester, and may persist in infant serum for months after birth. Live vaccines should be avoided in exposed infants for at least 6 months. Decisions about continuation during pregnancy should weigh disease control against neonatal immunosuppression risk.

Available Forms

Subcutaneous injection prefilled syringe (10 mg/0.1 mL, 20 mg/0.2 mL, 40 mg/0.4 mL, 80 mg/0.8 mL), Subcutaneous injection prefilled pen (40 mg/0.4 mL, 80 mg/0.8 mL), Subcutaneous injection single-dose vial (40 mg/0.8 mL — institutional use)

What It's Used For

Adalimumab is prescribed to treat:

• Rheumatoid arthritis, psoriasis, crohn's disease, and other inflammatory conditions • Various related conditions in the immunology category • Associated symptoms and complications

It is an important medication that helps manage these conditions effectively.

Dosage Quick Reference

These are general dosage guidelines. Your doctor will determine the appropriate dose for your specific situation.

Side Effects

Common side effects may include:

Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Adalimumab is a biologic that suppresses TNF-alpha-mediated immune signaling, so most clinically important interactions are immunological rather than pharmacokinetic.

  • Live or live-attenuated vaccines (e.g., MMR, varicella, yellow fever, intranasal influenza, BCG): Risk of disseminated vaccine infection. Avoid during therapy and bring vaccinations up to date before initiating treatment.
  • Other biologic DMARDs (e.g., etanercept, abatacept, anakinra, rituximab): Combining biologics produces no added benefit and substantially increases the risk of serious infection. Do not co-administer.
  • Methotrexate: Frequently combined with adalimumab in rheumatoid arthritis to reduce immunogenicity (anti-drug antibody formation) and improve sustained response. This is a beneficial interaction, not a contraindication.
  • CYP450 substrates with narrow therapeutic indices (e.g., warfarin, cyclosporine, theophylline): Chronic inflammation suppresses CYP450 enzyme activity. As adalimumab reduces inflammatory cytokines, CYP450 activity may normalize, potentially altering metabolism of these drugs. Monitor levels when starting or stopping adalimumab.
  • Abatacept: Concurrent use markedly increased the rate of serious infection in clinical trials without improved efficacy. Avoid combination.

Frequently Asked Questions

Some patients notice improvement within 2 to 4 weeks, but the full therapeutic effect typically develops over 12 to 24 weeks. For inflammatory bowel disease, the induction phase aims for response by week 8. If you have not seen meaningful benefit by 12 to 16 weeks at the recommended dose, discuss alternatives with your physician.
TNF inhibitors increase the risk of serious bacterial infections, reactivation of latent tuberculosis, hepatitis B reactivation, and invasive fungal infections such as histoplasmosis (notable in the southeastern US). Before starting therapy you will be screened for TB and hepatitis B. During treatment, report any persistent fever, cough, night sweats, or unexplained weight loss promptly.
Store prefilled syringes and pens in the refrigerator at 36–46 degrees F (2–8 degrees C). Do not freeze. Allow the device to reach room temperature for 15 to 30 minutes before injecting to reduce sting. Rotate injection sites between the front of the thighs and the abdomen (avoiding the area within 2 inches of the navel), and never inject into bruised, red, or hardened skin.
Inactivated vaccines — including the seasonal flu shot (injectable), pneumococcal vaccines, COVID-19 vaccines, recombinant zoster (Shingrix), and Tdap — are safe and recommended. Live vaccines such as MMR, varicella, yellow fever, and the nasal spray flu vaccine should be avoided. Ideally, complete needed live vaccines at least 4 weeks before starting adalimumab.
Inject the missed dose as soon as you remember, then resume your regular every-other-week schedule based on the new injection date. Do not give two doses on the same day to make up for a missed one. If more than a week has passed and you are unsure, contact your prescriber for guidance.

Questions to Ask Your Doctor

Consider discussing these topics at your next appointment:

  • What screening tests do I need before starting adalimumab, and how often will they be repeated?
  • Which of my current medications, supplements, or vaccines should I adjust around adalimumab?
  • What infection symptoms should prompt me to call you immediately versus wait until business hours?
  • How will we measure whether adalimumab is working, and at what point would we consider switching?
  • Are biosimilar versions of adalimumab appropriate for me, and could they reduce my out-of-pocket cost?
