What side effects can happen during an infliximab (Remicade) infusion?
Remicade (infliximab) is given by IV infusion, and some patients can have reactions while the drug is running or shortly after. Common infusion-related effects include headache, flushing, itching/rash, dizziness, nausea, and changes in blood pressure during the infusion. Serious infusion reactions are possible as well, and clinicians monitor closely during administration.
What side effects can happen after Remicade infusions?
After treatment, Remicade can cause side effects beyond the infusion window. Patients commonly report fatigue and flu-like symptoms after dosing. Some people develop rashes or experience worsening of certain infections. Because infliximab suppresses parts of the immune system, infections are a central risk—especially respiratory infections and other infections that could become severe.
What serious risks do patients worry about most (infections, allergic reactions, and more)?
The main serious concerns with Remicade are infections and immune-related complications. Infliximab can make it harder for the body to fight infections, so conditions that are mild for others can become dangerous in people on therapy. Serious allergic-type reactions can also occur.
There are also longer-term safety considerations with tumor necrosis factor (TNF) inhibitors, including risk for certain malignancies and rare immune-mediated issues. Whether these risks apply to an individual depends on dose, other medications, and overall health.
Who should be extra cautious before starting Remicade?
Risk can rise with factors such as a history of recurrent infections, active or latent infections (like tuberculosis or certain viral infections), chronic lung disease, and use of other immunosuppressing medicines (for example, corticosteroids or other biologics). Clinicians typically screen for infections before starting and may recommend vaccines and monitoring during treatment.
What should patients report right away after a Remicade infusion?
Patients should contact their clinician urgently for signs of a serious allergic or infusion reaction (such as trouble breathing, swelling of the face or throat, or severe hives). They should also report symptoms that could suggest infection—fever, chills, persistent cough, shortness of breath, burning with urination, or unusual severe fatigue.
How do Remicade side effects compare with other TNF blockers?
Remicade (infliximab) shares many class risks with other TNF inhibitors, especially infection risk and infusion/administration-related reactions (though the reaction profile can differ by drug and route). Choice among TNF inhibitors often comes down to efficacy for the specific condition, dosing schedule, prior response, and patient tolerance.
When do side effects tend to show up, and do they improve?
Infusion reactions most often occur during or soon after the infusion. Other effects (especially infection-related problems) can occur at any time during treatment and may increase the longer therapy continues, depending on overall immune status and other risk factors. If reactions occur, clinicians may adjust the infusion rate, use premedications, or reassess ongoing dosing.

If you tell me which side effects you’re experiencing (and when they started relative to the infusion), plus your condition (Crohn’s, ulcerative colitis, rheumatoid arthritis, etc.) and any other meds, I can help you sort what’s more likely infusion-related versus longer-term risks and what typically warrants urgent care.
