COVID-19 Risk After Golimumab (Symponi) Injection

Yes, your immune system is likely still somewhat weakened 11 weeks after a golimumab injection, potentially increasing your susceptibility to COVID-19 infection. This risk is based on golimumab's mechanism as a TNF inhibitor that causes immunosuppression, which continues for several months after administration.

Understanding Golimumab's Immunosuppressive Effects

Golimumab (Symponi) is a TNF inhibitor that works by suppressing parts of your immune system. According to the FDA label, TNF inhibitors like golimumab can "lower the ability of your immune system to fight infections" 1. While the specific risk for COVID-19 is not explicitly stated in the drug label, the general immunosuppressive effects are well-documented.

The immunosuppressive effects of golimumab typically persist for several months after injection, though they gradually diminish over time. At 11 weeks post-injection, you are still within the window of immunosuppressive effects, though they may be somewhat reduced compared to immediately after injection 2.

COVID-19 Risk Assessment

Several factors influence your specific COVID-19 risk:

  • Time since injection: At 11 weeks, you're still experiencing immunosuppressive effects, though they may be diminishing
  • Underlying condition: The condition being treated with golimumab affects your baseline risk
  • Age and comorbidities: Older age (>60 years) and pre-existing conditions increase COVID-19 risk in immunosuppressed patients 2
  • Vaccination status: COVID-19 vaccination significantly reduces risk even in immunosuppressed individuals

Recommended Precautions

Given your potentially increased susceptibility to COVID-19, consider these precautions:

  1. Maintain COVID-19 prevention measures:

    • Wear masks in high-risk settings
    • Practice good hand hygiene
    • Avoid crowded indoor spaces when possible
  2. Ensure vaccination status is current:

    • COVID-19 vaccination is strongly recommended for patients on immunosuppressive therapies 3
    • Consider booster doses if eligible, as immune response may be diminished in immunosuppressed individuals
  3. Monitor for symptoms:

    • Be vigilant for any signs of infection
    • Seek prompt medical attention if symptoms develop

Balancing Benefits and Risks

It's important to note that while golimumab does increase infection risk, the medication provides important benefits for your underlying condition. The British Society of Gastroenterology notes there is "no current evidence of increased risk of COVID-19 infection" specifically from anti-TNF therapy compared to other immunosuppressants 2.

Interestingly, some evidence suggests TNF inhibitors like golimumab may potentially have beneficial effects in severe COVID-19 by dampening the hyperinflammatory response ("cytokine storm") that can occur in severe cases 2.

When to Seek Medical Advice

Contact your healthcare provider if:

  • You develop any symptoms of COVID-19
  • You have specific concerns about your medication regimen
  • You need guidance on vaccination timing in relation to your golimumab schedule

Remember that while your immune system is somewhat compromised, maintaining your prescribed treatment regimen is generally recommended unless your healthcare provider advises otherwise.
