What side effects can Simponi (golimumab) cause?
Simponi (golimumab) is a tumor necrosis factor (TNF) blocker. Common side effects reported with golimumab include infections and reactions related to the medication’s immune effects. Reported side effects can include upper respiratory infections and symptoms such as cough or sore throat, as well as injection-site reactions (for people who self-inject) like redness, itching, or pain.
What are the most serious side effects people worry about?
The main serious risk with TNF blockers like Simponi is infection. Because the drug changes immune responses, it can make some infections more likely or more severe, including infections that may need urgent treatment.
Serious events that patients are typically advised to seek prompt medical care for include signs of a serious infection, such as:
- Fever, chills, or feeling very unwell
- Persistent cough or shortness of breath
- Burning pain with urination or other symptoms of worsening infection
Other serious concerns with TNF blockers can include immune-related reactions (such as new or worsening autoimmune symptoms), and changes that may require medical evaluation if symptoms appear.
How soon after starting Simponi can side effects show up?
Side effects can show up at different times:
- Injection-site reactions generally occur soon after a dose.
- Infection-related symptoms can occur at any time during treatment, especially when immune function is suppressed.
- Some immune or other adverse reactions may appear after several doses.
If symptoms develop, the key point is that new or worsening signs—especially possible infection symptoms—should be assessed promptly rather than waiting for the next dose.
What’s the difference between injection-site reactions and infections?
Injection-site reactions are usually localized and limited to the area where the medication is given, such as redness or discomfort. Infections are systemic or persistent symptoms (fever, worsening cough, shortness of breath, or other clear infection signs) and require medical attention.
When should you stop Simponi and call a doctor?
You should contact a clinician urgently if you develop symptoms that could indicate a serious infection (fever, severe illness, trouble breathing, or persistent/worsening symptoms). Do not take the next dose until a clinician advises whether to continue, especially if you’re being evaluated for infection.
Are there warning signs for people who are at higher risk of side effects?
People who are more likely to get infections (for example, those with other immunosuppressing conditions or therapies) may have greater risk while on Simponi. The prescribing information and your clinician’s guidance typically emphasize screening and monitoring before and during treatment.
Does Simponi have side effects with other medicines?
Simponi can interact with other immune-modifying treatments. Using it alongside other immunosuppressants can increase infection risk, so clinicians generally review current medications before starting and during treatment.
What should patients tell their doctor before taking Simponi?
Before starting, clinicians usually ask about:
- Current or recent infections
- Past tuberculosis exposure or history of TB
- Hepatitis B status
- Current medications that affect the immune system
These factors influence both the risk of side effects and the monitoring plan.
