For treating rheumatoid arthritis (RA), why is Simponi dosing more frequent than Simponi Aria dosing?
Studies looked at using Simponi in people with RA to find out the best dosage for treating this condition. Other studies looked at Simponi Aria’s dosages for RA.
Based on these studies, Simponi is given as a subcutaneous injection, and Simponi Aria is given as an IV infusion. Because you receive these drugs in different ways, your body breaks them down and absorbs them differently. So to treat RA effectively, Simponi injections need to be given more often than Simponi Aria infusions.
Your doctor will determine the best dose of Simponi or Simponi Aria to treat your condition.
What is a loading dose, and do Simponi and Simponi Aria require one?
A loading dose means that you take a higher dose at the beginning of treatment. This higher dose helps to manage symptoms more quickly.
Simponi and Simponi Aria both use a loading dose. But instead of the dose being higher, you take either drug more often in the beginning to get the same effect.
For more information about Simponi and Simponi Aria loading doses, talk with your doctor.

- other conditions you may have (see “Dosage adjustments” under “What are Simponi’s and Simponi Aria’s dosages?”)

Simponi: You’ll receive this drug as a subcutaneous injection (an injection under your skin). A healthcare professional will show you how to give yourself this injection. If you think an auto-injector might be easier to use than a prefilled syringe, ask your doctor whether SmartJect is a good treatment option for you.
You can inject Simponi in several places on your body: your front thigh, lower belly, or back of your upper arm. (It may be easier for another person to inject the drug into this location on your arm.) Learn more about how to inject Simponi on the manufacturer’s website.
Simponi Aria: You’ll receive this drug as an intravenous (IV) infusion (an injection into a vein given over time). A healthcare professional will give you the infusion in hospital, doctor’s office, or infusion center, and it’ll usually take about 30 minutes.

Your doctor or pharmacist may be able to recommend pharmacies that offer these accessibility features if your current pharmacy doesn’t.
If you miss a dose of Simponi, give yourself an injection of the drug as soon as you remember. You can continue your regular treatment schedule after that.
If you have trouble remembering to take your dose of Simponi, try using a medication reminder. This can include using a timer or setting an alarm.
If you miss an appointment for your dose of Simponi Aria, call your doctor right away to reschedule.

I have a sinus infection. Do I need to stop taking Simponi until I feel better?
Before or during Simponi treatment, tell your doctor about any infection you may have, including a sinus infection. They’ll likely want to work out how serious your infection is and how your body is reacting to it. It’s possible they may order blood tests or imaging tests to do this.
