This site is intended for patients prescribed SIMPONI (golimumab). If you are a Healthcare Professional then go to the HCP site or if you are a member of the public, please visit our public site.


Please continue to take your medication as instructed by your doctor or pharmacist. If you are concerned that you may have symptoms of COVID-19 or you are concerned about having been in contact with someone who has symptoms of COVID-19 then self-isolate, consult NHS 111 ( and also contact your GP or referring centre (consultant or clinical nurse specialist) for further advice.

Getting Started

Healthcare at Home

SIMPONI delivered straight to your door

Delivery van

After your doctor has prescribed SIMPONI, they will sign you up for the Healthcare at Home delivery service if it is appropriate for you. An advisor will phone to organise your delivery, for a time and place that suits you, free of charge.

We can offer advice on any queries you might have, such as:

  • Organising collection of your sharps bin
  • Advice on taking your medication when on holiday
  • If you have trouble with your injection device
  • Taking SIMPONI with other medications
Putting syringe into a sharps bin
Looking after SIMPONI

Keep your SIMPONI in the fridge, between 2°C and 8°C.

30 days

You also have the option to store it at room temperature (below 25°) for a single period of up to 30 days.


Once you choose to do this, make sure you write a new expiry date (30 days time) on the package so you'll know how long you can keep it for.

Do NOT return SIMPONI to the fridge if it has reached room temperature.

DISCARD your SIMPONI if not used by the NEW expiry date you have written on the carton, or the original one printed on the carton - whichever is the easier.

The SmartJect

The SmartJect pen has been designed in collaboration with patients and nurses so that taking your treatment is as easy as possible:

  • Preloaded
  • Disposable
  • Short, thin needle which is hidden from view
  • Inject with the push of a button
  • Available in both 50mg and 100mg doses (your doctor will prescribe the most appropriate dose for you)

SIMPONI is also available in a prefilled, 50mg disposable syringe.

Before you inject


Take your SIMPONI out of the fridge, but keep it in its outer carton, until it reaches room temperature - about 30 minutes.

Injecting it cold can be uncomfortable!

Although your healthcare professional should have taken you through how to self inject, this step-by-step guide is here for you to refer to at any time. If you have not been trained please contact your doctor, nurse or pharmacist.

Where you can inject

Middle Thigh

Front of the middle thigh

Lower Abdomen

Lower abdomen, at least 5cms (2 inches) below the belly button

Upper Arm

Outer area of the upper arm (if you are not administering the injection yourself)

Do not inject

  • Directly below the belly button
  • Tender or bruised areas
  • Red, hard or scaly areas
  • Areas that have scars or stretch marks
  • If you might be pregnant (contact your doctor)
  • If you have any signs of illness or infection such as a sore throat, cough, cold or fever (contact your doctor)

You should avoid injecting into the same place twice in a row. This is especially important if you need more than one injection for each monthly dose.

It may help to note down which area you use each time (e.g. right side of lower abdomen) to help make sure you use a different area the next time you inject. This is especially important if more than one injection is needed for each dose.
