Simponi (golimumab) is a tumor necrosis factor (TNF) blocker (or inhibitor). It's used to treat many types of inflammatory conditions in adults, such as rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), and ulcerative colitis (UC). Simponi (golimumab) is given as an injection under the skin, typically once per month. Side effects of this medication include upper respiratory tract infections, injection-site reactions, and high blood pressure.
Simponi (golimumab) is a type of biologic disease-modifying antirheumatic drug (DMARD) that's classified as a tumor necrosis factor (TNF) blocker (or inhibitor). TNF is a protein in the body that plays a key role in inflammation. By blocking TNF, Simponi (golimumab) lowers inflammation in your body to treat pain and swelling in your joints and gut caused by autoimmune conditions.

Tips for under-the-skin injections of Simponi (golimumab):
Both Simponi and Simponi Aria are medications that contain golimumab as the active ingredient. Both medications are used for rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS). One difference is that only Simponi is approved for ulcerative colitis (UC), while only Simponi Aria is approved for polyarticular juvenile idiopathic arthritis (PJIA). Another difference is that Simponi is only approved for adults, but Simponi Aria can be used in children as young as 2 years old for PsA and PJIA. Lastly, Simponi is given as an injection under the skin, whereas Simponi Aria is given as an infusion into the veins over 30 minutes. Talk to your healthcare professional (HCP) if you have specific questions about either brand name.
In general, it takes about 10 weeks for most of Simponi (golimumab) to leave your body after you've been taking this medication for a while. This timeframe is estimated based on the half-life of Simponi (golimumab) and can differ from person to person. Talk with your prescriber if you have more questions about how long this medication stays in your body.
People who took Simponi (golimumab) in clinical studies didn't report weight gain as a side effect. But taking Simponi (golimumab) can cause or worsen symptoms of heart failure, including weight gain due to fluid build-up. Speak with your prescriber right away if you experience unusual weight gain after starting Simponi (golimumab).
Simponi (golimumab) can cause certain side effects that lead to fatigue. For example, Simponi (golimumab) can raise the risk for infections (e.g., cold, flu), heart failure symptoms, and lupus-like symptoms. All of these conditions can cause you to feel tired or fatigued. Let your healthcare team know if you feel a noticeable drop in your energy level after starting Simponi (golimumab). They can examine you to better understand what might be causing your symptoms. If needed, they might ask you to pause Simponi (golimumab) treatment.
Simponi (golimumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Simponi (golimumab) can affect your body's ability to fight off infections. This raises your risk of serious or life-threatening bacterial, viral, or fungal infections. Serious infections are more likely to happen if you’re older than 65 or if you have other long-term conditions. Your risk is higher if you’re already taking other medications that weaken your immune system (e.g., steroids, methotrexate). Before starting Simponi (golimumab), tell your prescriber about your medical conditions and medications so they can make sure Simponi (golimumab) is appropriate for you.
Treatment with Simponi (golimumab) can also cause new or old tuberculosis (TB) infections to come back. Similarly, the medication can reactivate the hepatitis B virus (HBV) if you're a carrier of the virus. For these reasons, you'll need to get tested for both TB and HBV before starting Simponi (golimumab) and get treatment if you test positive (meaning you're infected with TB or HBV).
If you develop symptoms of an infection (e.g., fever, cough, difficulty breathing, diarrhea, weakness, sweating, chills) while taking Simponi (golimumab), get medical help right away. Your healthcare team might ask you to stop taking Simponi (golimumab) so your body can fight the infection.
Though rare, people who took other tumor necrosis factor (TNF) blocker have reported developing certain types of cancers, including leukemia, lymphoma, and skin cancer. Because Simponi (golimumab) is a TNF blocker, it might also raise the risk of getting cancers. The risk is higher for people who are younger than 18 years old, taking other medications that weaken your immune system (e.g., mercaptopurine, azathioprine (Imuran)), or have severe inflammatory conditions. Your prescriber will assess your risk before starting Simponi (golimumab) and monitor you while you're taking it. If you experience symptoms, such as swollen lymph nodes in your neck, armpits, or groin, fatigue, weight loss, loss of appetite, frequent nosebleeds, or lumps on your skin, contact your prescriber.
Simponi (golimumab) can cause new or worsening heart failure. Let your prescriber know if you currently have heart failure, since you’ll need to be closely monitored while taking this medication. If you have any new or worsening symptoms of heart failure (e.g., shortness of breath, swelling in your legs, ankles, or feet, irregular heartbeat, unable to exercise, tiredness or weakness) while taking Simponi (golimumab), stop the medication and contact your HCP.
Although rare, TNF blockers like Simponi (golimumab) have been linked to new or worsening nervous system problems. These problems can include nerve damage and multiple sclerosis. Tell your provider if you have any neurological problems before starting Simponi (golimumab). Also let your HCP know if you get dizziness, muscle weakness or spasms, changes in vision, or loss of balance while you're taking Simponi (golimumab).
Simponi (golimumab) can cause a lupus-like syndrome, which is a condition where your body's immune system attacks itself. If this happens, you might experience flu-like symptoms, including fever and pain in your muscles and joints. Stop taking Simponi (golimumab) and contact your prescriber if you have any of these symptoms. Once you stop taking the medication, your symptoms should go away.
Although rare, people taking TNF blockers like Simponi (golimumab) have reported having low blood cell counts. This can raise the risk of serious infections, bleeding, and anemia. If your blood counts drop too low, you'll probably need to stop taking Simponi (golimumab). If you develop any signs of infection (e.g., fever, tiredness, chills, cough, trouble breathing) or signs of blood problems (pale skin, fast heart rate, lightheadedness, blood in your urine or stool), contact your HCP right away.
Your healthcare team shouldn't prescribe Simponi (golimumab) along with Kineret (anakinra) or Orencia (abatacept). Taking these medications together can raise the risk of serious side effects, including severe infections, without any additional benefits. Let your healthcare team know if you're already taking either Kineret (anakinra) or Orencia (abatacept) before starting Simponi (golimumab).
Serious allergic reactions have been reported after using Simponi (golimumab). These reactions can include rash, hives, trouble breathing, swelling of the face or lips, and anaphylaxis. Get medical help right away if you experience an allergic reaction to Simponi (golimumab).
The inside of the removable autoinjector cap and the needle shield of the prefilled syringe contains dry natural rubber, an ingredient that is very similar to latex. Touching the shield or prefilled syringe can cause a severe allergic reaction if you're allergic to latex or rubber. Let your prescriber know if you're allergic to these ingredients.
Simponi (golimumab) is given as an injection under the skin (subcutaneous or SQ) either in the front of the thighs or lower stomach (at least 2 inches from the belly button).
Note: Golimumab is also available as the brand name Simponi Aria, which is given as an infusion into the veins (IV)
