What side effects does Remicade (infliximab) most often cause?
Remicade’s most commonly reported side effects are typical of medicines that suppress or modulate the immune system. The most frequent include:
- Upper respiratory infections (like colds, sinus infections, or bronchitis)
- Headache
- Nausea
- Stomach pain or abdominal discomfort
- Fever
What infections should patients watch for on Remicade?
Because Remicade affects tumor necrosis factor (TNF), it can make infections more likely. Patients are generally advised to watch for signs of infection, including:
- Persistent or worsening cough or shortness of breath
- Fever, chills, or flu-like symptoms
- Burning or pain with urination
- Unusual fatigue or weakness that comes with other infection symptoms
If an infection develops, clinicians may delay dosing or evaluate promptly, especially for serious infections.
Is nausea, headache, or stomach pain common?
Yes. Nausea, headache, and abdominal/stomach discomfort are among the more common non-infectious side effects reported with Remicade.
When should someone call a doctor urgently?
Seek urgent medical attention if side effects suggest a serious infection or another urgent complication—for example:
- High fever or fever that doesn’t go away
- Severe shortness of breath, chest pain, or confusion
- Symptoms that rapidly worsen
- Signs of a serious allergic reaction (such as hives, facial swelling, or trouble breathing)
Are infusion reactions common?
Remicade is given by IV infusion, and infusion-related reactions can occur. Symptoms can include headache, fever, chills, rash, itching, or feeling unwell during or shortly after an infusion. Clinicians monitor closely during administration.
