Hyrimoz Drug Interactions: What to Avoid and What to Tell Your Doctor

Because Hyrimoz (adalimumab-adaz) works by modifying your immune system, it can interact with other medications in important ways — increasing your risk of serious infections or reducing the effectiveness of certain treatments. Here's a complete guide to the most clinically significant drug interactions with Hyrimoz, plus what to tell your doctor before you start.

Most Important: Tell Your Doctor About ALL Your Medications

Before starting Hyrimoz, make sure your doctor and pharmacist know about every medication, supplement, vitamin, and herbal product you take — even if it's over-the-counter. This includes medications you take occasionally (like ibuprofen or acetaminophen), supplements like fish oil or turmeric, and any biologics or immunosuppressants you take or recently stopped.

Major Interactions: Do Not Use Together

1. Abatacept (Orencia) — Major Interaction

Combining Hyrimoz with abatacept (a T-cell costimulation blocker used in RA) significantly increases the risk of serious infections with no demonstrated added clinical benefit. In clinical trials, the combination produced a higher proportion of serious infections and no improvement in disease control compared to either drug alone. The combination is not recommended.

2. Anakinra (Kineret) — Major Interaction

Anakinra is an interleukin-1 (IL-1) receptor antagonist. When combined with a TNF blocker like Hyrimoz, clinical data showed a significantly greater proportion of serious infections and neutropenia (dangerously low white blood cell counts), with no added benefit for RA. The combination is not recommended.

3. Other TNF Blockers — Major Interaction

Combining Hyrimoz with other TNF inhibitors — such as etanercept (Enbrel), infliximab (Remicade), certolizumab (Cimzia), or golimumab (Simponi) — is not recommended. The combination provides no additional therapeutic benefit and substantially increases the risk of life-threatening infections.

4. Live Vaccines — Major Interaction

You should NOT receive live or live-attenuated vaccines while taking Hyrimoz. This includes:

Live attenuated influenza vaccine (nasal spray flu vaccine — FluMist; injectable flu vaccine is fine)

MMR vaccine (measles, mumps, rubella)

Varicella (chickenpox) vaccine

Yellow fever vaccine

BCG (tuberculosis) vaccine

There is also concern about the safety of live vaccines in infants exposed to adalimumab products in utero (during pregnancy), as the drug can cross the placenta and be present in the infant's system for months after birth. Talk to your pediatrician if you were on Hyrimoz during pregnancy.

Inactivated (killed) vaccines — including the standard flu shot, Shingrix (shingles), Pneumovax (pneumococcal), Tdap, and COVID-19 vaccines — are safe to receive while on Hyrimoz, though immune response may be blunted. Talk to your doctor about the optimal timing.

Moderate Interactions: Use With Caution

5. Other Biologic DMARDs — Moderate Interaction

Combining Hyrimoz with other biologic disease-modifying antirheumatic drugs — such as rituximab (Rituxan), secukinumab (Cosentyx), ustekinumab (Stelara), or tocilizumab (Actemra) — has not been well studied and is generally not recommended due to the potential for additive immunosuppression and increased infection risk. A higher rate of serious infections was observed when patients previously treated with rituximab received a TNF blocker.

6. Corticosteroids (Prednisone, etc.) — Moderate Interaction

Corticosteroids (like prednisone or methylprednisolone) are often used alongside Hyrimoz, particularly during Crohn's disease induction or RA flares. However, combining immunosuppressants increases overall infection risk — especially in older patients (65+) and those with other medical conditions. If you're on both, close monitoring for infections is essential.

Minor Interactions: Generally Safe, but Monitor

7. Methotrexate — Minor Interaction (Often Intentional)

Hyrimoz is commonly prescribed in combination with methotrexate in RA and other conditions. This is intentional — methotrexate reduces the formation of anti-drug antibodies (ADA) against adalimumab, which can preserve Hyrimoz's effectiveness over time. The combination is generally well tolerated, but both drugs carry infection and liver toxicity risks, so regular monitoring (CBC, liver function tests) is essential.

8. NSAIDs (Ibuprofen, Naproxen, etc.) — Minor Interaction

Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen are often continued during Hyrimoz treatment for symptom management, particularly in RA, PsA, and AS. There is no major pharmacokinetic interaction, but both NSAIDs and Hyrimoz can affect kidney function with long-term use. Inform your doctor if you take NSAIDs regularly.

Special Considerations: Alcohol and Supplements

Moderate alcohol consumption is generally not contraindicated with Hyrimoz, but if you are also on methotrexate, alcohol significantly increases liver toxicity risk and should be avoided entirely. Herbal supplements with immune-stimulating properties (like echinacea) may theoretically counteract Hyrimoz's immunosuppressive effects, while those with immune-suppressing properties add to the infection risk. Discuss all supplements with your doctor.
