What side effects can Simponi (golimumab) cause?
Simponi (golimumab) is a TNF-alpha inhibitor. Its side effects largely come from two areas: increased infection risk and immune-related reactions.
Commonly reported side effects include:
- Upper respiratory infections (such as colds)
- Headache
- Nausea
What serious side effects should patients watch for?
Patients taking Simponi should seek medical care right away if they develop signs of a serious infection or other urgent complications, such as:
- Fever, chills, or persistent flu-like symptoms
- Shortness of breath, chest pain, or coughing that doesn’t go away
- Severe skin infections or rapidly worsening redness/pain
- Unusual fatigue, weight loss, or night sweats
Because TNF inhibitors can affect the immune system, they can also increase the risk of reactivation of infections in some people (for example, tuberculosis and certain viral infections), so clinicians typically screen for these before starting treatment.
Simponi can also cause or worsen other immune-related problems, including:
- Allergic reactions (for example, rash, swelling of the face, or trouble breathing)
- Liver problems (yellowing of skin/eyes, dark urine, severe nausea/vomiting)
- Blood count changes (unusual bruising, bleeding, or frequent infections)
How do side effects differ by condition (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, ulcerative colitis)?
Simponi is used for different conditions depending on the formulation and prescribing indication. The types of side effects are generally similar across TNF inhibitors because the mechanism is the same, but the exact risk balance can vary based on:
- The underlying disease being treated
- Other medicines taken at the same time (especially other immune suppressants)
- Personal infection risk (history of tuberculosis, chronic infections, older age, etc.)
What side effects might look like infections?
On Simponi, infections can range from mild to severe. Symptoms that should not be ignored include:
- Persistent fever or fever that returns after improving
- A worsening cough or shortness of breath
- Painful urination, flank pain, or recurrent urinary infections
- New skin sores, boils, or wound infections
If an infection is suspected, clinicians often hold the medication and evaluate the cause.
When should someone stop Simponi or call a doctor urgently?
Call a clinician urgently or seek emergency care for:
- Signs of serious infection (high fever, severe shortness of breath, severe or rapidly worsening symptoms)
- Allergic reaction symptoms (hives, facial swelling, trouble breathing)
- Signs of liver injury (yellow skin/eyes, dark urine)
- Severe or unusual neurologic symptoms (for example, new weakness or vision changes)
