What side effects are most common with Simponi Aria (golimumab)?
Simponi Aria (golimumab) can cause side effects, including reactions related to the infusion and effects seen across TNF-inhibitor medicines. Commonly reported issues include infusion-site reactions (such as pain, swelling, or rash where the IV medication goes in), headaches, nausea, and upper respiratory-type symptoms like cough or sore throat.
Because golimumab suppresses parts of the immune system, patients are also watched for signs of infection. Any infection symptoms (fever, chills, worsening cough, burning with urination, or unexplained fatigue) need prompt medical attention.
What serious side effects should you watch for?
The most important serious risks with Simponi Aria involve infections and immune-system effects. Patients are typically counseled to seek urgent care if they develop signs of serious infection, such as:
- Fever or chills
- Shortness of breath
- Severe weakness or feeling very ill
- Symptoms that worsen quickly
TNF blockers can also increase risk of certain immune-related conditions. Clinicians generally screen for tuberculosis and hepatitis B before starting, because these infections can reactivate with TNF inhibitors.
What infusion reactions can happen during or after treatment?
Since Simponi Aria is given as an IV infusion, some people experience infusion-related reactions. Symptoms can include rash, itching, dizziness, low blood pressure, or trouble breathing during the infusion or shortly after. The infusion center monitors patients during administration, and your prescribing team may adjust premedication or the infusion plan if reactions occur.
How do side effects compare with other TNF inhibitors (like Humira or Remicade)?
Simponi Aria is in the same drug class as other TNF inhibitors, so the overall side-effect pattern is similar: infection risk and immune-related concerns are shared across the class. The biggest practical differences usually come from dosing schedule and the route of administration (IV for Simponi Aria vs. injections for some others), which can affect the type of administration-related reactions people notice.
When do side effects tend to appear?
Milder infusion-related effects can show up during the infusion or within a short time after. Some adverse effects related to immune suppression, especially infections, can develop any time during treatment. If symptoms start after a dose, the timing still matters less than the severity and whether you have fever or signs of infection.
What should you do if you get a side effect?
- Mild symptoms (like mild headache or nausea) can often be managed while on treatment, but you should still report them to your clinician.
- Stop and get medical advice urgently for symptoms that could signal serious infection, allergic reaction, or breathing problems.
- Do not delay care if you have fever, shortness of breath, or rapidly worsening symptoms.
Who is at higher risk for serious side effects?
Risk is generally higher for people with:
- A history of recurrent or chronic infections
- Prior tuberculosis exposure or untreated TB
- Past or current hepatitis B infection
- Conditions or medications that further suppress the immune system
Are there warnings about vaccinations or pregnancy?
TNF inhibitors are commonly associated with guidance around vaccines (especially avoiding live vaccines while on treatment). Pregnancy and breastfeeding decisions also require clinician guidance because risks and benefits need to be weighed for each patient.
If you tell me what symptoms you’re experiencing (and when they started), I can help you narrow down which side effect category it most resembles and what level of urgency is typical to discuss with your prescriber.

I don’t have the provided Simponi Aria prescribing information or a side-effect reference in the chat, so I can’t cite specific incidence rates or exact wording from authoritative labeling here. If you paste the “Warnings and Precautions” / “Adverse Reactions” sections from your Simponi Aria leaflet or share the link you’re using, I can summarize the side effects from that document accurately.
