Simponi reduces inflammation and is used to relieve the symptoms of certain autoimmune disorders such as certain kinds of arthritis and ulcerative colitis.

Simponi Overview


Simponi is a prescription medication for the treatment of ulcerative colitis, moderately to severely active rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis.

Simponi belongs to class of medications called DMARDs, or disease modifying antirheumatic drugs. These medications work by blocking tumor necrosis factors (TNFs), factors partly responsible for over-inflammation in certain diseases.

This medication comes in a once-monthly, self-injectable form to be injected under the skin (subcutaneous injection). It also comes as an injection to be given through the vein (IV) by a healthcare provider.

Common side effects include upper respiratory infection and redness at the site of injection.

Simponi Precautions

Serious side effects have been reported with Simponi including:

Simponi is a medicine that affects your immune system. Simponi can lower the ability of your immune system to fight infections. Some people have serious infections while taking Simponi, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses that spread throughout their body. Some people have died from these serious infections.

  • Your doctor should test you for TB and hepatitis B before starting Simponi.
  • Your doctor should monitor you closely for signs and symptoms of TB during treatment with Simponi.

You should not start taking Simponi if you have any kind of infection unless your doctor says it is okay.

    • feel very tired
  • are being treated for an infection
  • get a lot of infections or have infections that keep coming back
  • have diabetes, HIV, or a weak immune system. People with these conditions have a higher chance for infections.
  • have TB, or have been in close contact with someone with TB
  • live, have lived, or traveled to certain parts of the country (such as the Ohio and Mississippi River valleys and the Southwest) where there is an increased chance for getting certain kinds of fungal infections (histoplasmosis, coccidioidomycosis, blastomycosis). These infections may happen or become more severe if you use Simponi. Ask your doctor if you do not know if you have lived in an area where these infections are common.
  • have or have had hepatitis B
  • use the medicine Orencia (abatacept), Kineret (anakinra), Actemra (tocilizumab) or Rituxan (rituximab)

After starting Simponi, call your doctor right away if you have any symptoms of an infection. Simponi can make you more likely to get infections or make worse any infection that you have.


  • For children and adults taking TNF-blocker medicines, including Simponi, the chances of getting cancer may increase.
  • There have been cases of unusual cancers in children and teenage patients taking TNF-blocking agents.

Inform MD

Before taking Simponi, tell your doctor about all of your medical conditions. Especially tell your doctor if you...

  • have a history an infection
  • have a history of any type of cancer
  • have a history of heart failure
  • have or have had a condition that affects your nervous system (e.g., multiple sclerosis or Guillain-Barré syndrome)
  • have recently received or are planning to receive a vaccine
  • have a baby and you were using Simponi during your pregnancy. Let your baby's doctor know before your baby receives any vaccine. Your baby may have an increased chance of getting an infection, particularly within 6 months after birth.
  • are allergic to rubber or latex, as the needle cover on the syringe and autoinjector is made with dry natural rubber
  • are pregnant, planning to become pregnant, or are breastfeeding

Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements.

Simponi and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Simponi falls into category B. There are no well-controlled studies of Simponi in pregnant women, and so it is unknown whether Simponi can cause fetal harm when administered to a pregnant woman. Simponi should be used during pregnancy only if clearly needed.

In addition, you should let your baby's doctor know before your baby is given any vaccine. There may be an increased risk of infection with your newborn, particularly within 6 months after birth.

Simponi and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is unknown whether Simponi can pass into human breast milk. Because many drugs are able to pass into human milk, and because of the potential for adverse effects in nursing infants while using Simponi, a decision should be made whether to stop nursing or the use of Simponi between you and your doctor.

Simponi Usage

Self-Injectable Simponi 

Simponi is meant for use under the supervision of a physician. After proper training in injection technique, a patient may self inject with Simponi if a physician determines that it is appropriate.

Simponi comes in a liquid form meant for injection directly underneath the skin (subcutaneous injection). It is given once per month.

If self-injecting Simponi at home, allow the prefilled syringe or autoinjector to rest at room temperature outside the carton for 30 minutes before injection. Do not warm Simponi in any other way.

Visually inspect the solution for particles and discoloration through the viewing window before use. Simponi should be clear and colorless or light yellow in color. The solution should not be used if discolored, cloudy, or if particles are visible. Any leftover product remaining in the prefilled syringe or prefilled autoinjector should not be used.

Sites for injection should be done at a different spot from the last injection. Injections should never be given into areas where the skin is tender, bruised, red, hard, or damaged in any way.

For a complete list of instructions on how to use Simponi, refer to your doctor or a pharmacist for more information.

Simponi FDA Warning



Patients treated with Simponi are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.

Simponi should be discontinued if a patient develops a serious infection.

Reported infections with TNF-blockers, of which Simponi is a member, include:

  • Active tuberculosis, including reactivation of latent tuberculosis. Patients with tuberculosis have frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent tuberculosis before Simponi use and during therapy. Treatment for latent infection should be initiated prior to Simponi use.
  • Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized, disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness.
  • Bacterial, viral, and other infections due to opportunistic pathogens, including Legionella and Listeria.

The risks and benefits of treatment with Simponi should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection.

Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with Simponi, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy.


Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, of which Simponi is a member.
