Anti TNF Inhibitor

Understanding TNF inhibitors

Conventional DMARD’s such as Methotrexate and Sulfasalazine were the only treatments available prior to Anti-TNF (or Biologics). These conventional treatments did not always work for everyone either on their own or in combination with other medications. In the 1990’s Versus Arthritis helped to fund research into other treatments. A –TNF medications were designed to treat inflammatory arthritis by acting directly on the disease itself. Biologic therapies are currently given to patients whom have already tried appropriate treatments for their condition and have not responded well to them.

Before starting medication
Please read the written information and watch the video’s on A-TNF before starting this medication. It is important you understand how this medications works and why it is being prescribed; as well as how to take the medication correctly. You can view this information as often as you feel is necessary.

Answering some of your questions about Anti-TNF Inhibitors

Medications and delivery service

  • Etanercept (Benepali); administered once a week. Delivered via Healthnet
  • Adalimumab (Amgevita); administered every 2 weeks. Delivered via Sciensus
  • Certilizumab (Cimzia); administered every 2 weeks ( this has a loading dose of 400mg (2x200mg) week 0, 2 and 4 then 200mg every 2 weeks). Delivered via Sceinsus.
  • Golimumab (Simponi); administered once a month on the same date each month. Delivered via Sciensus
  • Infliximab (Remsema); this is given as an infusion on our day case until every 4 to 8 weeks depending on need. It is now available as an injection but for some conditions it requires a loading dose of a few IV infusions at first, but the nurse will discuss this with you in more detail.

It can take 4-5 weeks for the account to be put in place and for the delivery to arrive. Once the injections have been delivered place them in the fridge. Nurse training is arranged via the delivery company.

  • Medication is issued through rheumatology NOT your GP.
  • The delivery company will contact you to arrange a date & time.
  • A nurse from the same company should offer 2 training visits to teach you how to self-inject.
  • The injections MUST be stored in the fridge.
  • One dose per PEN/Syringe.
  • The delivery company will provide a sharp’s bin once you have injected the PEN/Syringe place it in the bin provided.
Pregnancy and breastfeeding

Seek advice from your consultant or nurse before planning a family.
The recent British Society of Rheumatology (2022) guidelines recommend stopping TNF medication is those with low disease activity or low risk of flaring at:

  • Infliximab at 20 weeks
  • Adalimumab and Golimumab at 28 weeks
  • Etanercept at 32 weeks
  • Certolizumab (Cimzia) is safe throughout pregnancy

Those with active or poorly controlled disease can continue TNF throughout pregnancy but live vaccines have to be avoided in infants until 6 months of age. With the exception of Certolizumab which does not require any alternations to the infant vaccination schedule.

  • Anti-TNFs are compatible with breastfeeding although data is limited
  • Men do not need to stop anti-TNFs when trying for a family, although again data is limited

Your team will advise accordingly-let us know in plenty of time!

General advice
  • Alcohol no more than 14 units a week, limit the amount & avoid binge drinking.  Do you know your safe limits? Found out here
  • Avoid live vaccines.  This includes, but is not limited to, rabies, MMR, yellow fever and some forms of shingles vaccine.  You should advise any travel clinic that you are taking immunosuppression.
  • Flu, Covid and Pneumonia vaccines are inactive vaccines – this means they are not live vaccines.  Your GP will call you for these vaccines and we strongly advise that you have these. More information can be found here
  • Avoid contact with chicken pox. (As adults we tend to develop shingles rather than chicken pox, you may require anti-viral treatment from your GP).
  • Prevent sunburn. (Check for changes in the skin and monitor freckles and moles for such as changes in size, shape, colour and weeping). Have any changes checked with your GP.

Sun burn can lead to skin damage which increases the risk of developing skin cancers.  We recommend “slip, slap, slop” – slip on a shirt to cover up, slap on a hat, slop on the sunscreen. Find out more here
